Range Selection

The transmission has 5 range positions: P, R, N, D and L.

Scheme 119

Scheme 119: Range Selection

Park

In the PARK position

  1. there is no powerflow through the transaxle.
  2. the parking pawl locks the final drive.
  3. the engine may be started.
  4. the ignition key may be removed.

Reverse

In the REVERSE position

  1. the vehicle may be operated in a rearward direction, at a reduced gear ratio.
  2. engine braking will occur.
  3. the reverse lamps will be activated.

Neutral

In the NEUTRAL position

  1. there is no powerflow through the transmission.
  2. the output shaft is not held and is free to turn.
  3. the engine may be started.

Drive

DRIVE is the normal position for the best fuel economy.

DRIVE provides

  1. automatic shifts gears 1st through 6th.
  2. apply and release of the torque converter clutch.
  3. maximum fuel economy during normal operation.

Manual L Position

In this position the transaxle will upshift and downshift 1st through 4th gear with extended shift scheduling. Engine braking will occur in 1st through 4th gears.

This position provides

  1. 1st through 4th gear operation only.
  2. extended shift scheduling.
  3. increased engine braking.

Shift Patterns

Based on signals from the sensors, the system controls gear shift lockup.

Downshifts

Under certain conditions the transmission will downshift automatically to a lower gear range (without moving the range selector lever). There are 3 categories of automatic downshifts

  1. Coastdown
  2. Torque demand
  3. Forced or kickdown shifts

Coastdown

The coastdown downshift occurs when the vehicle is coasting down to a stop.

Kickdown

For maximum acceleration, the driver can force a downshift by pressing the accelerator pedal to the floor. A forced downshift into a lower gear is possible below calibrated speeds. Specifications for downshift speeds are subject to variations due to tire size, engine and transmission calibration requirements.

Automatic Gearshift Control

In automatic gearshift control, based on each gearshift pattern, SSA and SSB turn ON or OFF and SSC, SSD, SSE and SSF are operated linearly according to information that includes vehicle speed, the degree to which the accelerator is open and brake signal.

Driver Adaptive Shift Control

This automatic transaxle does not have a driving mode selection switch that allows drivers to select a mode themselves. The vehicle is ordinarily in adaptive mode. However, when specific conditions are met, the transmission control unit (TCU) selects a shifting pattern appropriate to driving conditions from all of the shifting patterns and switches automatically.

  1. GREEN - Mode 1 - Switched from mode 2 to warm up the transmission fluid. This mode acts to protect the transaxle before the adaptive mode.
  2. GREEN - Mode 2 - After engine start-up, warm-up speed is increased for a certain period when transmission fluid temperature is low and the vehicle speed is 0.
  3. HIGH TEMP - When fluid temperature becomes too high, this mode activates lock-up at an earlier timing to stop the temperature rise and lower the temperature.
  4. DOWN SLOPE - When driving down a slope, the transmission control module (TCM) detects a down slope based on the engine control unit signal and output rpm. TCM switches to down slope mode to alleviate the load to the brake by down shifting.

Gear Shift Control

When the shift lever is moved from N to D or from N to R, after the engine is started, a shift control solenoid assembly (SSC, SSD, SSE) is used for the fluid pressure required by C1 clutch or C3 clutch and appropriately regulated fluid pressure is supplied to the clutch, engaging smoothly without shock.

Reverse Converter Control

If the shift lever is moved from N to R while the vehicle is moving forward and the transaxle shifts into REVERSE, the wheels will be locked, which is extremely dangerous. In order to avoid this, the TCM inhibits the transaxle from shifting into REVERSE while moving forward.

Geartrain

The geartrain consists of the planetary gearsets, apply components, final drive gearset and differential.

GEAR RATIO CHART

Differential

The differential allows the halfshafts and wheels to rotate at different speeds during cornering.

The differential assembly consists of the following components

  1. Differential case (part of the final drive carrier)
  2. Two pinion gears supported by a pinion shaft
  3. Two side gears supported by the differential case and halfshafts

When driving in a straight line, both front wheels rotate at relatively the same speed. This means both side gears are rotating at the same speed, as well, while both pinion gears revolve (but do not rotate) with the side gears. During cornering, the wheel on the outside of the turn is forced to rotate faster than the wheel on the inside of the turn. Since the side gears must now rotate at different speeds, the pinion gears rotate on the pinion shaft allowing the drive axles to rotate at different speeds while still transferring output torque.

C-1 Clutch

The C1 clutch connects the front planetary carrier to the rear sun gear of the rear planetary set. The C1 clutch is applied in 1st (typical operation during engine braking), 2nd, 3rd and 4th gears.

C-2 Clutch

The C2 clutch connects the intermediate shaft to the rear planetary carrier. The C2 clutch is applied in 4th, 5th and 6th gears.

C-3 Clutch

The C3 clutch connects the front planetary carrier to the middle sun gear of the rear planetary set. The C3 clutch is applied in 3rd and 5th gears, and also in reverse when the vehicle speed is 7 km/h (4 mph) or less.

B-1 Brake

The B1 brake locks the middle sun gear of the rear planetary gear set. The B1 brake is applied in 2nd and 6th gears.

B-2 Brake

The B2 brake locks the rear planetary carrier in reverse gear when the vehicle speed is 7 km/h (4 mph) or less.

F-1 One-Way Clutch

The Fl one way clutch locks the counterclockwise rotation of the rear planetary carrier during 1st gear operation (during both normal operation and engine braking).

Valve Body

The valve body supplies fluid by switching the fluid circuit for the hydraulic pressure that is generated by the fluid pump. Based on the hydraulic pressure generated by the fluid pump the TCM sends control signals to the solenoid valves in accordance with vehicle conditions. Upon activation of the solenoid valve, the control hydraulic pressure to the clutch and brakes is determined (according to the equilibrium with the obtained hydraulic pressure) and gear shift and lockup are accomplished. In addition, an appropriate amount of fluid is supplied to the torque converter, planetary gears and lubricating parts.

Transmission Control Module (TCM) Control Function

In automatic gear shift control, based on each gear shift pattern, SAA and SBB turn ON or OFF and SSC, SSD, SSE and SSF are operated linearly according to information that includes vehicle speed, the degree to which the accelerator is open and brake signals. For the gear and solenoid operation chart, refer to the GENERAL SPECIFICATION tables.

The transmission range (TR) sensor is built in the transmission control module (TCM), it detects the automatic transmission range information via the Hall-effect sensor and outputs the information to the TCM. The TCM reads the voltage and adjusts the automatic transmission range.

Brake Pedal Position (BPP) Switch

The brake pedal position (BPP) switch tells the powertrain control module when the brakes are applied. The torque converter clutch disengages when the brakes are applied and the BPP switch closes when the brakes are applied and opens when they are released.

Scheme 120

Scheme 120: Transmission Fluid Temperature (TFT) Sensor

The transmission fluid temperature sensor, which is integrated within the transmission wiring, is installed on the front of the valve body. It directs the fluid temperature within the hydraulic pressure control circuit and transmits a signal based on that temperature to the TCM. Through this it controls gear shift, lockup and slip in response to changes in fluid temperature for smooth shifting across wide fluid temperature zones.

Scheme 121

Scheme 121: Transaxle 3-Way Shift Solenoids (SSA, SSB)

The transaxle 3-way solenoid assembly (SSA) is installed on the middle valve body. The transmission 3-way solenoid assembly (SSB) is installed on the front valve body. The solenoids turn ON and OFF in response to signals output from the TCM. According to the ON or OFF status of SSA or SSB, the 1st gear engine brake operates or the gear shifts into REVERSE. As a fail-safe function, if any transmission 3-way solenoid assembly abnormality occurs, the TCM will disable the current to the solenoids.

Scheme 122

Scheme 122: Shift Control Solenoids (SSC, SSD, SSE, SSF)

The shift control solenoid assembly (SSC, SSD, SSE, SSF) is installed on the front valve body. The solenoids linearly control hydraulic pressure in response to signals, output from the TCM. Through this, it controls hydraulic pressure to the clutch (C1, C2, C3) and brakes (B1) for smooth shifting. According to the combination of ON or OFF status of the shift control solenoid assembly, the transmission shifts from 1st gear into 6th gear and vice versa. As a fail-safe function, if any shift control solenoid assembly abnormality occurs, the TCM will disable the current to the shift control solenoids.

Scheme 123

Scheme 123: Pressure Control Solenoid (PCA)

The pressure control solenoid (PCA) is installed on the front valve body. Based on a signal indicating the degree to which the throttle is opened, engine torque, and according to a duty ratio predetermined in the TCM, the solenoids control line hydraulic pressure by linearly changing the comparable throttle hydraulic pressure. Through this, it controls operating hydraulic pressure to the clutch and brakes for smooth shifting. As a fail-safe function, if any shift control solenoid assembly abnormality occurs, the TCM will disable the current to the shift control solenoids. The line pressure is maximized, if the shift control solenoid assembly current is disabled when any abnormality other than locking occurs.

Speed Sensor

The 2 speed sensors are installed in the transaxle case. One speed sensor detects revolutions of the intermediate shaft's C2 drum as input shaft revolutions. The other speed sensor detects the counterdrive gear as output shaft revolutions. These signals are transmitted to the TCM. Based on these signals, the TCM controls engine torque, shift timing and lockup.

Adaptive Shift Control

The TCM has an adaptive learning strategy to electronically control the transaxle which will automatically adjust the shift feel. The first few hundred miles of operation of the transaxle may have abrupt shifting. This is a normal operation. If the battery has been disconnected for any reason it will need to be kept disconnected for approximately 20 minutes to reset the adaptive shift pressure strategy or use the diagnostic tool to carry out the keep alive memory (KAM) reset.

Scheme 124

Scheme 124: Torque Converter Clutch (TCC) Solenoid

The torque converter clutch (TCC) solenoid is used in the transaxle control system to control the application, modulation and release of the torque converter clutch.

The TCC control solenoid is installed on the front valve body. Based on engine rpm, throttle opening degree signals and speed sensor signals, it linearly controls clutch hydraulic pressure. Through this, engagement and slip are controlled. As a fail-safe function, if any control solenoid assembly abnormality occurs, the TCM will disable the current to the TCC solenoid.

Know and Understand the Concern

In order to correctly diagnose a concern, first understand the customer complaint or condition. Customer contact may be required in order to begin to verify the concern. Understand the conditions as to when the concern occurs. For example

  1. Hot or cold vehicle temperature
  2. Hot or cold ambient temperatures
  3. Vehicle driving conditions
  4. Vehicle loaded/unloaded

After understanding when and how the concern occurs, proceed to verifying the concern.

Verification of Condition

This section provides information which must be used in both determining the actual cause of customer concerns and carrying out the appropriate procedures.

The following procedures must be used when verifying customer concerns for the transmission.

Determine Customer Concern

Note. Some transaxle conditions may cause engine concerns. An electronic pressure control short circuit can cause engine misfiring. The torque converter clutch not disengaging will stall the engine.

Determine customer concerns relative to vehicle use and dependent driving conditions, paying attention to the following items

  1. Hot or cold vehicle operating temperature
  2. Hot or cold ambient temperatures
  3. Type of terrain
  4. Vehicle loaded/unloaded
  5. City/highway driving
  6. Upshift
  7. Downshift
  8. Coasting
  9. Engagement (harsh or soft)
  10. Noise/vibration - check for dependencies, either RPM dependent, vehicle speed dependent, shift dependent, gear dependent, range dependent or temperature dependent

Shift Linkage Check

Hydraulic leakage at the manual control valve can cause delay in engagements and/or slipping while operating if the linkage is not correctly adjusted. Refer to AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS for shift linkage adjustment.

Check TSBs

Refer to all technical service bulletins which pertain to the concern and follow the procedure.

Before Pinpoint Tests

Note. Prior to entering pinpoint tests, check the powertrain control module (PCM) wiring harness for correct connections, bent or broken pins, corrosion, loose wires, correct routing, correct seals and their condition. Check the PCM, sensors and actuators for damage. Refer to the INTRODUCTION - GASOLINE article .

Note. If a concern still exists after electrical diagnosis has been carried out, refer to DIAGNOSIS BY SYMPTOM .

If DTCs appear while carrying out the on-board diagnostics, refer to the DIAGNOSTIC TROUBLE CODE (DTC) CHARTS for the appropriate repair procedure. Prior to entering pinpoint tests, refer to any TSBs for transaxle concerns.

Engine Idle Speed Check

Refer to the INTRODUCTION - GASOLINE article for diagnosis and testing of the engine idle speed.

Scheme 125

Scheme 125: Pressure Test
CAUTIONIf the pressure is low at stall, do not continue with the test or further transaxle damage will occur. Do not maintain wide open throttle in any transaxle range for more than 5 seconds.

Note. In order to connect the pressure gauge to the transaxle, you will need to use an O-ring to pipe adapter (5/16-24 to 1/8 inch pipe thread adapter).

This test verifies that the pressure is within specification.

  1. Connect a pressure gauge to the appropriate pressure tap.
  2. Start the engine and check the pressures, see the Pressure Charts to determine if the pressures are within specification.
