Continuously Variable Transaxle On-Vehicle Service - Except Lancer Evolution Mitsubishi Lancer Evolution X

GENERAL INFORMATION

F1CJA model has been established.

CVT GENERAL INFORMATION

The transaxle consists of the torque converter and gear train. The three-element, one-stage, two-phase type torque converter with a built-in torque converter clutch has been adopted. The gear train of F1CJA transaxle consists of 1 set of multi-disc type clutches, 1 set of multi-disc type brakes, and 1 set of planetary gears which are composed of a sun gear, carrier, annulus gear, 2 sets of pulleys and 1 set of steel belts.

INVECS-III CONTROL

INVECS-III has been newly developed based on INVECS-II utilizing continuous variable characteristics of CVT.

Scheme 3

To select the pulley ratio which can provide the driving force corresponding to the driver's intention and vehicle conditions, TCM selects the optimal pulley ratio and determines the shift strategy to obtain it by detecting the vehicle driving conditions such as the vehicle speed, accelerator angle. Then, it outputs the command to the stepper motor, controls in/out flow of the line pressure to/from the primary pulley, positions the movable pulley of the primary pulley, and controls the gear ratio.

ENGINE BRAKE FEATURE ON THE DESCENDING SLOPE

Pulley ratio is controlled to obtain the engine brake suitable for the driver's feelings.

Scheme 4

Learning compensation is made to meet the tastes of a driver by judging the amount of the engine brake from the application of the accelerator or the brake.

Scheme 5

If the foot leaves the accelerator pedal during driving on the ascending slope (called lift foot), driving capability is secured by preventing excessive upshifting.

Scheme 6

Ratio patterns are continuously switched according to the driving method of a driver.

Scheme 7

Scheme 8

Scheme 9

The shift change is performed in the entire shift range from the lowest to the highest pulley ratio.

Scheme 10

By limiting the shift range to the area around the lowest pulley ratio, the powerful driving force and engine brake is secured.

Scheme 11

When the sport mode is switched ON with the selector lever or paddle shift, the fixed shifting line is determined. The upshift/downshift operation enables to shift in steps according to the predetermined shifting line, providing M/T-like shifting. The 6-speed transmission which is suitable for sporty driving is adopted.

Scheme 12

Scheme 13

By carefully controlling the direct operating pressure depending on the driving conditions, the shock-free direct operation from low speed has been achieved.

INTRODUCTION TO CVT DIAGNOSIS

The CVT can exhibit any of the following symptoms: noise or vibration is generated, Transmission fluid leaks, the vehicle does not move forward or backward. The causes of these symptoms could come from: Incorrect mounting, the Transmission fluid may be low, or a component of the transaxle may be faulty.

The following items are suspected as causes for the INVECS-III troubles: malfunction of the TCM, the sensors, the switches, the harness or connectors.

CVT DIAGNOSTIC TROUBLESHOOTING STRATEGY

Use these steps to plan your diagnostic strategy. If you follow them carefully, you will find most CVT malfunctions.

1. Gather as much information as possible about the complaint from the customer.
2. Verify that the condition described by the customer exists.
3. Check the vehicle for any CVT Diagnostic Trouble Codes (DTCs).
4. If you can not verify the condition and there are no DTCs, the malfunction is intermittent. For information on how to cope with intermittent malfunctions, refer to «HOW TO COPE WITH INTERMITTENT MALFUNCTIONS»(/mitsubishi/lancer-evolution/x-2007-2016/remont/hoistjack/#general-information-except-lancer-evolution__how-to-cope-with-intermittent-malfunctions) .
5. If you can verify the condition but there are no DTCs, or the system can not communicate with scan tool, refer to the «SYMPTOM CHART»(/mitsubishi/lancer-evolution/x-2007-2016/remont/automatic-trans/#continuously-variable-transaxle-on-vehicle-service-except-lancer-evolution__trouble-symptom-chart) .
6. If there is a DTC, record the number of the code, then erase the code from memory using scan tool.
7. Reconfirm the symptom with a Road Test.
8. If a DTC is set again, go to the «DIAGNOSTIC TROUBLE CODE CHART»(/mitsubishi/lancer-evolution/x-2007-2016/remont/automatic-trans/#continuously-variable-transaxle-on-vehicle-service-except-lancer-evolution__diagnostic-trouble-code-chart) .
9. If a DTC is not set again, the malfunction is intermittent. For information on how to cope with intermittent malfunctions, refer to «HOW TO COPE WITH INTERMITTENT MALFUNCTIONS»(/mitsubishi/lancer-evolution/x-2007-2016/remont/hoistjack/#general-information-except-lancer-evolution__how-to-cope-with-intermittent-malfunctions) .
10. After repairs are completed, conduct a Road Test duplicating the complaint conditions to confirm the malfunction has been eliminated.

WARNING INDICATOR

When any malfunction occurs in the items related to the CVT system, which are described below, the symbol (A) continues being displayed in the information screen in the multi information display.

Check if the diagnosis code is set when the symbol (A) continues being displayed in the information screen in the multi information display.

Note. When the symbol (B) is displayed in the information screen in the multi information display, the transmission fluid temperature is high. (Symbol (B) is turned on when the fluid temperature is approximately 140°C (284°F) or higher and turned off automatically when the fluid temperature drops below approximately 137°C (279°F).)

Scheme 15

ON-BOARD DIAGNOSTICS

The transaxle control module (TCM) monitors its input/output signals (some signals all the time and others under specified conditions). When an irregular signal is initially monitored, the TCM decides that a malfunction has occurred and records the occurrence as a diagnostic trouble code. There are 36 diagnostic items. The diagnostic results can be read with scan tool. Diagnostic trouble codes are kept in memory by direct battery feed. The codes are retained in memory even if the ignition switch is in the "LOCK" (OFF) position. DTCs are not erased even after the battery terminals and the TCM connector are disconnected. In addition, the diagnostic trouble code can also be erased by scan tool.

Note. If a sensor is disconnected when the ignition switch is in the "ON" position, a diagnostic trouble code is stored in memory. In this case, erase the DTC using scan tool.

The 36 diagnostic items are displayed in numeric order.

TORQUE CONVERTER STALL TEST

This test measures the maximum engine speed at the time the torque converter stalls with the selector lever in the "D" or "R" position. With this test, the holding abilities of the clutch and brake that are incorporated in the transaxle can be checked.

1. Check the transmission fluid level, transmission fluid temperature, and engine coolant temperature. Transmission fluid level: In the "HOT" mark on the dipstick Transmission fluid temperature: 70 - 80°C (158 - 176°F) Engine coolant temperature: 80 - 100°C (176 - 212°F) NOTE: Use M.U.T.-III. to measure the transmission fluid temperature.
2. Raise the vehicle.
3. Pull the parking brake lever, and then fully depress the brake pedal.
4. Start the engine. CAUTION: Do not maintain the WOT condition for 5 seconds or longer. When continuing the stall test, make sure that the fluid temperature does not exceed 80°C (176°F). If the transmission fluid temperature exceeds 80°C (176°F), run the engine at around 1,000 r/min for 1 minute or longer to lower the transmission fluid temperature to 80°C (176°F) or less.
5. Move the selector lever to the "D" range and fully depress the accelerator pedal. Quickly read the maximum engine speed at this time. Standard value - Stall speed: 2,400 - 2,900 r/min
6. Move the selector lever to the "R" range, and then repeat the previous step. Standard value - Stall speed: 2,400 - 2,900 r/min

JUDGEMENT OF TORQUE CONVERTER STALL TEST RESULTS

1. Stall speed is high when selector lever is in both "D" and "R" ranges. Malfunction of the torque converter (Torque converter and input shaft spline are slipping) Malfunction of the valve body Damaged wiring harness and connectors Malfunction of TCM
2. Stall speed is high only when selector lever is in the "D" range. Forward clutch is slipping
3. Stall speed is high only when the selector lever is in the "R" range. Reverse brake is slipping

TRANSMISSION FLUID CHECK

Scheme 74

Scheme 75

1. Drive the vehicle until the transmission fluid is warmed up to the normal operating temperature 70 - 80°C (158 - 176°F). NOTE: Use M.U.T.-III. to measure the transmission fluid temperature. NOTE: When a certain amount of time is required to warm up the transmission fluid to the normal operating temperature 70 - 80°C (158 - 176°F), check the oil level referring to the characteristics chart.
2. Park the vehicle on a level surface.
3. Move the selector lever to every position to fill the torque converter and the hydraulic circuit with the transmission fluid, and then move the selector lever to "P" or "N" range.
4. Wipe clean the area around the dipstick, and then remove the dipstick to check the condition of the transmission fluid. NOTE: If the transmission fluid smells burnt or is excessively deteriorated or dirty, the transmission fluid is contaminated with particles of the metal bushings and friction material. In these cases, the transaxle must be overhauled.
5. Check that the transmission fluid level is within the "H" area on the dipstick. If the fluid level is low, add the transmission fluid to the "H" level. Transmission fluid: DIA QUEEN CVTF-J1 NOTE: When the transmission fluid level is low, the oil pump sucks air together with the transmission fluid, and produces air bubbles in the hydraulic circuit. The air bubbles in the hydraulic circuit decreases the hydraulic pressure, causing the delayed shift or slippage of the belt, clutch, and brake. When the transmission fluid level is too high, the fluid is stirred by the gear and foams up, and the problems similar to those when the transmission fluid level is low will occur. In either case, air bubbles cause the overheat and oxidation of the transmission fluid, which prevents normal operation of the valve, clutch, and brake. Beside, when the transmission fluid is foamy, it flows out of the transaxle vent hole. This may be taken as the fluid leakage by mistake.
6. Insert the dipstick securely.

Scheme 76

1. Remove the drain plug on the bottom of the transaxle case to drain the transmission fluid. Draining amount: Approximately 5.1 dm 3 (5.39 qt)
2. Install the drain plug with a new gasket to the transaxle case, and tighten it to the specified torque. Tightening torque: 34 ± 2 N.m (25 ± 2 ft-lb) CAUTION: If the transaxle case becomes full before filling 5.1 dm 3 (5.39 qt) of transmission fluid, stop filling the transmission fluid.
3. Fill in the new transmission fluid through the filler tube. Filling amount: Approximately 5.1 dm 3 (5.39 qt) Transmission fluid: DIA QUEEN CVTF-J1
4. Start up the engine and let it idle for 1 to 2 minutes.
5. Move the selector lever to every position, and then move it to the "P" or "N" range.
6. Stop the engine and perform the above steps 1 to 5 again.
7. Stop the engine, and discharge a small amount of transmission fluid to check for fouling. If fouling is found, repeat steps 1 to 5 until clean transmission fluid comes out.
8. Drive the vehicle until the transmission fluid is warmed up to the normal operating temperature 70 - 80°C (158 - 176°F), and check the transmission fluid level. It must be within the "H" area on the dipstick. NOTE: The "COLD" level is for reference only. Use the "H" level as the criteria. NOTE: Use M.U.T.-III. to measure the transmission fluid temperature. NOTE: When a certain amount of time is required to warm up the transmission fluid to the normal operating temperature 70 - 80°C (158 - 176°F), check the fluid level referring to the characteristics chart.
9. Adjust the transmission fluid level to the specified level. Refill the transmission fluid when the fluid level is low, and drain the transmission fluid through the drain plug when the fluid level is high.
10. Securely insert the dipstick into the filler tube.
11. TCM records the deterioration level of the transmission fluid. After replacing the transmission fluid with new one, use M.U.T.-III to reset the deterioration level recorded in TCM.

FLUSHING COOLERS AND TUBES

Required Special Tool

MB995062: Flushing Tool

When a transaxle failure has contaminated the transmission fluid, the transaxle must be flushed. The transmission fluid warmer (transmission fluid cooler) on the transaxle must also be replaced. The torque converter must also be replaced with an exchange unit. This will ensure that metal particles or sludged transmission fluid are not later transferred back into the reconditioned (or replaced) transaxle. There are two different procedures for flushing coolers and lines. The recommended procedure is to use special tool MB995062 Flushing Tool. The other procedure is to use a hand suction gun and mineral spirits.

Scheme 77

1. Remove the cover plate filler plug on special tool MB995062. Fill the reservoir 1/2 to 3/4 full with fresh flushing solution. Flushing solvents are petroleum based solutions generally used to clean transaxle components. Do not use solvents containing acids, water, gasoline, or any other corrosive liquids.
2. Reinstall the filler plug on special tool MB995062.
3. Verify that the pump power switch is turned "OFF." Connect the red alligator clip to the positive battery terminal. Connect the black alligator clip to a good ground.
4. Disconnect the cooler lines at the transaxle. NOTE: When flushing the transaxle cooler and lines, always reverse flush.
5. Connect the pressure line to the OUTLET line (from cooler).
6. Connect the return line to the INLET line (to cooler).
7. Turn the pump "ON" for two to three minutes to flush the cooler(s) and lines. Monitor the pressure readings. Clear the return lines. Pressure readings should stabilize below 138 kPa (20 psi) for vehicles equipped with a single cooler and 208 kPa (30 psi) for vehicles equipped with dual coolers. If flow is intermittent or exceeds these pressures, replace the cooler(s).
8. Turn the pump "OFF."
9. Disconnect the suction line from the reservoir at the cover plate. Disconnect the return line at the cover plate and place it in a drain pan.
10. Turn the pump "ON" for 30 seconds to purge flushing solution from the cooler(s) and lines. Turn the pump "OFF."
11. Place the suction line into a one quart container of DIA QUEEN CVTF-J1 transmission fluid.
12. Turn the pump "ON" until all transmission fluid is removed from the one quart container and lines. This purges any residual cleaning solvent from the transaxle cooler(s) and lines. Turn the pump "OFF."
13. Disconnect the alligator clips from the battery. Reconnect the flusher lines to the cover plate, and remove the flushing adapters from the cooler lines. Reconnect the cooler lines.

OIL COOLER FLOW CHECK

After the new or repaired transaxle has been installed, fill to the proper level with DIA QUEEN CVTF-J1. The flow should be checked using the following procedure

1. Disconnect the OUTLET line (from cooler) at the transaxle and place a collecting container under the disconnected line.
2. Run the engine at curb idle speed with the shift selector in neutral.
3. If transmission fluid flow is intermittent or it takes more than 20 seconds to collect one quart of transmission fluid, replace the cooler.
4. If flow is within acceptable limits, reconnect the cooler line. Then fill the transaxle to the proper level, using DIA QUEEN CVTF-J1.
