Automatic Transmission: Other Saab 9-5 II

Shifting

The TCM can determine whether to leave a gear engaged or to change up or down. What it does is determined mainly by the gear that is currently engaged, the speed of the output shaft and the position of the accelerator pedal. The TCM changes gear by applying or releasing a friction element in the transmission. The application is regulated with PWM from the respective solenoid.

The gear can also be changed manually with the selector lever in D position if using the Tap Up/Tap Down switch. The switch is hardwired to the BCM which converts the information into a HSCAN message that is used by the TCM.

The maximum shift speed is at 7000 rpm.

Lock Up

The torque converter clutch is activated at a steady speed when there is no need of torque amplification. If the brakes are applied or acceleration increases, the function will be deactivated.

Safety Features

To protect the transmission there are temperature programs to prevent overheating. The TCM can choose to raise the shift points and activate lock up more often if the oil temperature is too high.

The reverse gear will not be activated if the car is travelling faster than 7 km/h (4 mph). If the power supply to the solenoids fails, it is still possible to drive the car. The gear position D/M gives 2nd gear and P-R-N will work as usual. In case of a major fault in the transmission, mechanical or electrical, the TCM will cut the supply to the solenoids in a controlled manner (limp home).

In case the TCM detects a failure it will go into emergency mode.

Special Gear Change Program

If an uphill gradient is detected, the gears will change at higher engine speeds and each gear will remain engaged for longer periods.

The Sport Mode can be engaged by a switch. Upon detecting the sport mode request TCM adapts the shift lines in order to enable a more progressive driving.

General

The changing duration is calculated in real time by comparing the speeds of the input shaft and output shaft. The control module knows the gear ratio for the current gear and the target gear and can follow the change in gear ratio until the changing process is complete. The time it took to change gear is then compared with the desired value for the gear change and an adaptation is made.

The adaptation is done by correcting the requested pressure for the applied friction element solenoid and the correction is then used the next time a change is made between these gears. The adaptation value is saved in a non-volatile memory and must be zeroed using a scan tool each time the TCM, transmission or valve housing is changed and after SPS programming.

After zeroing with a scan tool, it will usually only require a road test, see below, for the TCM to be able to adapt itself to the new conditions.

Transmission Indicators and Messages

The following transmission-related indicators and messages may be displayed on the Driving Information Center (DIC). For a complete listing and description of all vehicle indicators and messages, refer to INDICATOR/WARNING MESSAGE DESCRIPTION AND OPERATION .

TRANSMISSION HOT IDLE ENGINE: This message is displayed if the temperature exceeds 150°C for longer than 2 seconds.

SERVICE TRANSMISSION: This message displays when there is a problem with the transmission.

CHANGE TRANSMISSION FLUID: This message displays when the transmission oil needs to be changed.

5. Magnetic field

The TCM is mounted directly on top of the transmission. The selector lever is integrated in the control module. The TCM is mounted so that the selector lever shaft goes through the control module. The selector lever position is calibrated with a scan tool, there is no mechanical adjustment.

An exterior 16-pin connector connects to the car's electrical system. Underneath the control module is another connector (22-pin) that connects directly to the transmission. The TCM makes contact with all the transmission solenoids and sensors here.

Note. Magnetic fields from e.g. magnets and from high-current cables, such as starter cables and cables to auxiliary equipment, can interfere with the gear position sensor. A rule of thumb is max 1A per mm in distance from the control module. A starter cable carrying a current of 200A must therefore be kept at least 20 cm away from the control module.

The TCM has a microprocessor with clock, RAM memory and a programmable ROM. An internal bus connects the processor and memory with the I/O unit. The I/O unit reads values from the A/D converter for analogue inputs, digital inputs and bus, as well as activates the transistors' output stages.

Adaptive values are saved in a non-volatile memory (ROM). When changing transmission, these values must be zeroed using scan tool. After changing TCM they will be zeroed automatically after adding the control module using the scan tool.

Scheme 132

The transmission is electronically controlled by a control unit (TCM, Transmission Control Module). The TCM (1) is mounted directly on top of the transmission (2) and has one connector to the car's electrical system and one to the transmission. The gear position sensor is Hall type and integrated in the control module. The TCM is mounted so that the selector lever shaft goes through the control module. The gear lever sensor position is calibrated in position N with a scan tool, there is no mechanical adjustment. TCM controls the solenoids to maintain or change gear. The solenoids are controlled with PWM (Pulse Width Modulation) to achieve a variable flow of oil.

The determining factors for changing gear are two values; current gear and target gear. Current gear is the one engaged at the moment and the target gear is the one TCM wants to change to. As long as these to values are the same there will be no gear change. Gear changing is initiated only when the target gear differs from the current gear. It is mainly the vehicle speed and acceleration that determines the target gear in automatic transmissions. The vehicle speed is taken from a special sensor, output speed, while the acceleration is taken from the engine management system (ECM) via the high speed bus.

Gear changing must also follow a permitted schedule. If a direct change to the target gear is not present in the schedule, there will be an intermediate gear change. For example, if the vehicle is driven in fifth gear and the accelerator pedal suddenly indicates second gear as target gear (kickdown), shifting is from fifth to third and third to second. This is because shifting directly from fifth gear to second gear is not allowed.

When a gear change is carried out, TCM will calculate a requested pressure for each solenoid circuit. The pressure is converted to a requested current that later results in a PWM ratio. The requested pressure is modulated according to a predetermined procedure so that the gear change is made comfortable without unnecessary wear. Current engine torque taken from ECM via the high speed bus is used for this purpose. A higher pressure is required for higher engine torque.

TCM reads the resulting current to each solenoid and can finely adjust the PWM ratio so that the requested pressure (current) agrees with the actual current. The transmission does not have a pressure sensor so current pressure cannot be sent back to the control system. For this reason, the solenoids are calibrated very precisely.

Manual gear changing can be accomplished with the selector lever in position D using the up/down switch in the lever. A manual gear change must be fully completed before TCM will accept a new change command. The current gear is shown in the driver information center (DIC). The highest permitted gear for start is third. For safety's sake, there is an automatic downshift from sixth, fifth and fourth after kickdown if engine speed is below 2000 rpm.

TCM sends continuous information on the high speed bus concerning the engine torque allowed by the transmission. When changing gear this value drops and ECM limits engine torque if it exceeds this value.

The torque converter clutch is activated at steady speed in gears 3-6 when there is no need for any torque amplification. The slipping in procedure is regulated by comparing the speed on the input shaft with the engine speed obtained from ECM via the high speed bus. Lock up will not work at temperatures below 15°C (56°F). If the brake is depressed or acceleration increases, the function will be activated.

A reverse detent function prevents reverse gear being engaged if the car is travelling faster than 7 km/h when the selector lever is moved from N to R. Overrevving in gear position M will be prevented by not allowing changing down to take place if the speed is too high.

For high engine loads without a corresponding increase in speed one of two hill-climbing programs will be chosen. Gear changing is done at higher engine speeds and the gear will remain engaged for longer periods until the extra load ceases. These gearchange programs are used to avoid changing up and down unnecessarily, e.g. when driving up long inclines with trailer and to avoid overheating the transmission oil. The Sport Mode can be engaged by a switch. Upon detecting the sport mode request TCM adapts the shift lines in order to enable a more progressive driving. Special gear change programs are not activated at speeds above 150 km/h (93 mph). If a special gear change program is active when the speed increases to over 150 km/h (93 mph), the program will continue, however, until the load has normalized.

Limp Home

If the power supply to TCM or to the solenoids is cut, the car can still be driven. Gear position D/M will give 2nd gear and P-R-N will work as normal but the gear will be engaged roughly as there is no regulation.

In case of a major fault in the transmission, mechanical or electrical, TCM will cut the supply to the solenoids in a controlled manner. In most cases, the control module will attempt to maintain the current gear until the car has stopped. Subsequently, the control module will attempt to engage 2nd gear if D/M is selected. After this, the supply to the solenoids will be cut and the transmission will lose all electrical control.

If an invalid gear ratio or the wrong gear is detected, the engine torque will be limited to 170 Nm in reverse and 150 Nm forward. For other faults, the torque will be limited to higher values depending on failure.

Towing

The car may only be towed with the front pointing in the direction of travel. The selector lever must be in position N. National regulations concerning towing speeds must be adhered to. If legislation allows, the highest permitted towing speed is 50 km/h (30 mph) with all four wheels on the ground. The longest permitted towing distance is 50 km (30 miles). If the car should require towing for longer distances as 50 km (30 miles), the front wheels must be raised from the ground. If the front wheels has been raised, the highest permitted towing speed is 50 km/h (30 mph).

The engine cannot be started by pushing or towing the car.

The automatic transmission park lock control system is a safety system that prevents accidental shifting from the PARK position. The driver must depress the brake pedal before the park lever can be moved from the PARK position. The system consists of the following components

1. The automatic transmission park lock solenoid (serviced as the automatic transmission shift lock actuator), is located within the floor shift control assembly.
2. The body control module, which controls the voltage supply circuit of the park lock control solenoid.
3. The engine control module.

The body control module controls the voltage to the park lock control solenoid through the park lock control solenoid controlled voltage circuit. The following conditions must be met before the body control module will supply voltage to the park lock solenoid

1. The ignition is in the ON position.
2. The engine control module sends an input via GMLAN serial data to the body control module indicating the transmission is in the PARK position.
3. The body control module determines the brake pedal is applied according the brake pedal position.

Since the park lock control solenoid is permanently grounded, the body control module supplies voltage to the automatic transmission park lock control solenoid, unlocking the park lever allowing the driver to move the park lever out of the PARK position as the solenoid energizes. When the brake pedal is not applied, the body control module turns the control voltage output of the park lock control solenoid OFF, de-energizing the park lock control solenoid. The de-energized solenoid mechanically locks the park lever in the PARK position.

Electrical Function Check

Perform this procedure first in order to ensure the electronic transmission components are functioning properly. If these components are not checked, a simple electrical condition could be misdiagnosed.

1. Connect diagnostic tool.
2. Ensure the gear selector is in PARK and set the parking brake.
3. Start the engine.
4. Verify that scan tool data can be obtained. Refer to «CONTROL MODULE REFERENCES»(ref-653639-S11210668452014090100000) for typical data values. Data that is questionable may indicate a concern.
5. Monitor the TCC Brake Switch parameter while applying and releasing the brake pedal. The scan tool should display: Open when the brake pedal is applied. Closed when the brake pedal is released.
6. Check the garage shifts. Apply the brake pedal and ensure the parking brake is set. Move the gear selector through the following ranges: PARK to REVERSE REVERSE to NEUTRAL NEUTRAL to DRIVE Pause 2 to 3 seconds in each gear position. NOTE: Harsh engagement may be caused by any of the following conditions: Verify the gear engagements are immediate and not harsh. High engine idle speed-Compare engine idle speed to desired idle speed. High pressure will cause harsh shifts. A default condition caused by certain DTCs that result in maximum line pressure to prevent clutch slippage. NOTE: Soft or delayed engagement may be caused by any of the following conditions: Low idle speed-Compare engine idle speed to desired idle speed. Low fluid level Low pressure will cause soft or delayed shifts. Cold transmission fluid temperature (TFT)-Use the scan tool to determine TFT. Selector linkage-Inspect and adjust as necessary. Verify the gear engagements are immediate and not harsh.
7. Monitor transmission range on the scan tool, engine data list. 7.1. Apply the brake pedal and ensure the parking brake is set. 7.2. Move the gear selector through all ranges. 7.3. Pause 2 to 3 seconds in each range. 7.4. Return gear selector to PARK. 7.5. Verify that all selector positions match the scan tool display.
8. Check throttle position input. 8.1. Apply the brake pedal and ensure the parking brake is set. 8.2. Ensure the gear selector is in PARK. 8.3. Monitor the scan tool Calc. Throttle Position while increasing and decreasing engine speed with the throttle pedal. The scan tool Calc. Throttle Position percentage should increase and decrease with engine speed. If any of the above checks do not perform properly, record the result for reference after completion of the road test.

Adaptive Learning

Start driving the car and make the adaptive learning. Refer to TRANSMISSION ADAPTIVE FUNCTIONS .

Confirm Customer Complaint by Driving

Continue driving to verify the customer complaint. It might be useful to use manual shifting in order to verify the problem.

Check Oil Level and Oil Quality

After the driving is finalized and the complaint has been recorded

1. Check fluid level. Refer to «TRANSMISSION FLUID LEVEL AND CONDITION CHECK»(ref-653642-S41840466012014090100000) .
2. Check oil quality. If the oil is milky there is a water leakage into the transmission. Check the vent hose. If the oil smells burnt and its color is dark some disc may have been overloaded.
3. If the oil quality is too bad, change oil, make a new adaptive driving and the check if the problem is still there.

Poor Acceleration at Low Speed

If the stator is freewheeling at all times, the car tends to have poor acceleration from a standstill. At speeds above 50-55 km/h (30-35 mph), the car may act normally. For poor acceleration, you should first determine that the exhaust system is not blocked, and the transmission is in First gear when starting out.

If the engine freely accelerates to high RPM in NEUTRAL, you can assume that the engine and the exhaust system are normal. Check for poor performance in DRIVE and REVERSE to help determine if the stator is freewheeling at all times.

Poor Acceleration at High Speed

If the stator is locked up at all times, performance is normal when accelerating from a standstill. Engine RPM and car speed are limited or restricted at high speeds. Visual examination of the converter may reveal a blue color from overheating.

If the converter has been removed, you can check the stator roller clutch by inserting a finger into the splined inner race of the roller clutch and trying to turn the race in both directions. You should be able to freely turn the inner race clockwise, but you should have difficulty in moving the inner race counterclockwise or you may be unable to move the race at all.

If Shudder Occurs After TCC has Applied

If shudder occurs after the TCC has applied, most of the time there is nothing wrong with the transmission.

As mentioned above, the TCC is not likely to slip after the TCC has been applied. Engine problems may go unnoticed under light throttle and load, but they become noticeable after the TCC apply when going up a hill or accelerating. This is due to the mechanical coupling between the engine and the transmission.

Once TCC is applied, there is no torque converter, fluid coupling, assistance. Engine or driveline vibrations could be unnoticeable before TCC engagement.

Inspect the following components in order to avoid misdiagnosis of TCC shudder. An inspection will also avoid the unnecessary disassembly of a transmission or the unnecessary replacement of a torque converter.

1. Spark plugs - Inspect for cracks, high resistance or a broken insulator.
2. Coil - Look for a black discoloration on the bottom of the coil. This indicates arcing while the engine is misfiring.
3. Fuel injector - The filter may be plugged.
4. Vacuum leak - The engine will not get a correct amount of fuel. The mixture may run rich or lean depending on where the leak occurs.
5. EGR valve (Petrol) - The valve may let in too much or too little unburnable exhaust gas and could cause the engine to run rich or lean.
6. MAP sensor - Like a vacuum leak, the engine will not get the correct amount of fuel for proper engine operation.
7. Carbon on the intake valves - Carbon restricts the proper flow of air/fuel mixture into the cylinders.
8. Flat cam - Valves do not open enough to let the proper fuel/air mixture into the cylinders.
9. Oxygen sensor - This sensor may command the engine too rich or too lean for too long.
10. Fuel pressure - This may be too low.
11. Engine mounts - Vibration of the mounts can be multiplied by TCC engagement.
12. Axle joints - Check for vibration.
13. TP Sensor (Petrol) - The TCC apply and release depends on the TP Sensor in many engines. If the TP Sensor is out of specification, TCC may remain applied during initial engine loading.
14. Cylinder balance - Bad piston rings or poorly sealing valves can cause low power in a cylinder.
15. Fuel contamination - This causes poor engine performance.

General Method

1. Verify that the leak is transmission fluid.
2. Thoroughly clean the suspected leak area.
3. Operate the vehicle for 24 km (15 mi), or until normal operating temperatures are reached.
4. Park the vehicle over clean paper or cardboard.
5. Switch off the engine.
6. Look for fluid spots on the paper.
7. Make the necessary repairs.

Powder Method

1. Thoroughly clean the suspected leak area with solvent.
2. Apply an aerosol type leak tracing powder to the suspected leak area.
3. Operate the vehicle for 24 km (15 mi), or until normal operating temperatures are reached.
4. Switch off the engine.
5. Inspect the suspected leak area.
6. Trace the leak path through the powder in order to find the source of the leak.
7. Make the necessary repairs.

Dye and Black Light Method

A fluid dye and black light kit is available from various tool manufacturers.

1. Follow the manufacturer instructions in order to determine the amount of dye to use.
2. Operate the vehicle for 24 km (15 mi), or until normal operating temperatures are reached.
3. Detect the leak with the black light.
4. Make the necessary repairs.

Find the Cause of the Leak

Pinpoint the leak and trace the leak back to the source. You must determine the cause of the leak in order to repair the leak properly. For example, if you replace a gasket, but the sealing flange is bent, the new gasket will not repair the leak. You must also repair the bent flange. Before you attempt to repair a leak, check for the following conditions, and make repairs as necessary

1. Fluid level/pressure is too high.
2. Plugged vent or drain-back holes.
3. Improperly tightened fasteners.
4. Dirty or damaged threads.
5. Warped flanges or sealing surface.
6. Scratches, burrs, or other damage to the sealing surface.
7. Damaged or worn gasket.
8. Cracking or porosity of the component.
9. Improper sealant used, where applicable.
10. Incorrect gasket.

Seals

1. Fluid level/pressure is too high.
2. Plugged vent or drain-back holes.
3. Damaged or worn seal.
4. Cracks in component.
5. Manual shaft or output shaft surface is scratched, nicked, or damaged.
6. Loose or worn bearing causing excess seal wear.

Transmission Valve Body Cover

1. Incorrectly tightened bolts.
2. Improperly installed or damaged gasket/seal.
3. Damaged mounting face.
4. Incorrect gasket seal.

Transmission Case Leak

1. Loose or damaged oil cooler lines/seals.
2. Worn or damaged axle shaft oil seal.
3. Loose line pressure pipe plug or fluid level pipe plug.

Leak at the Transmission Vent

1. Overfilled system.
2. Water or coolant in the fluid. The fluid will appear milky. Check vent hose mounting.
3. Plugged vent.

Transmission Overheats

1. Perform the «DIAGNOSTIC SYSTEM CHECK - VEHICLE»(ref-653639-S05362277832014090100000) before using the Symptom Tables in order to verify that all of the following are true: There are no DTCs set. The control modules can communicate via the serial data link.
2. Review the system operation in order to familiarize yourself with the system functions. Refer to «AUTOMATIC TRANSMISSION SHIFT LOCK CONTROL DESCRIPTION AND OPERATION»(ref-653642-S39016328762014090100000) .

VEHICLES CONCERNED

Saab 9-5 (650) only year MY 2011 with 4 cylinder Petrol & Bio Power engine (A20 NFT) equipped with automatic transmission AF40, Gen II.

BACKGROUND

If the engine has stopped when the "D" or "R" mode is engaged, the transmission will not engage the clutch after a re start if the engine rpm is below 2000 rpm.

CONDITIONS

This problem is due to a software (SW) parameter, set by the supplier in the Transmission Control Module (TCM) unit.

ACTION

1. Start the engine, engage the transmission, and increase the rpm to 2000 rpm: The transmission will now engage the clutch.
2. Drive the car until the engine reaches normal temperature, and the transmission oil is warm then maintain a speed of minimum 50 km/h (30 mph) to make sure that the transmission lock up function is activated.
3. Confirm that the gearshift performs as expected before returning the car to the customer.

Note. If car does not behave as expected in point 3, repeat points 2-3.
