6 Speed - Automatic Transaxle/Transmission
Transaxle Drive Cycle TestCAUTION: Prior to carrying out the transaxle drive cycle test, make sure that the transaxle is full of fluid.
NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.
After carrying out the Quick Test, use the following Transaxle Drive Cycle Test for checking continuous codes:
NOTE: The Transaxle Drive Cycle Test must be followed exactly. Malfunctions must occur multiple times consecutively for shift error or torque converter clutch (TCC) code to set.
NOTE: When carrying out the Transaxle Drive Cycle Test, see the solenoid operation chart for correct solenoid operation. Refer to Pinpoint Tests -Non OSC Equipped Vehicle. Pinpoint Tests - Non OSC Equipped Vehicle
1. Record and then erase Quick Test codes.
2. Warm engine to normal operating temperature.
3. Make sure transmission fluid level is correct.
4. With transaxle in DRIVE, moderately accelerate from stop to 80 km/h (50 mph). This allows the transaxle to shift into 6th gear. Hold speed and throttle steady for minimum of 15 seconds. Brake to a stop and remain stopped for minimum of 20 seconds.
5. Repeat Step 4 at least 5 times.
6. Carry out Quick Test and record continuous codes.
- If DTC's are present, refer to Diagnostic Trouble Code (DTC) Charts. 6 Speed Automatic Transaxle Service all non-transaxle DTC's first as they can directly affect the operation of the transaxle. Repeat the Quick Test and Road Test to verify the correction. Erase DTC's, carry out the drive cycle test, and repeat the Quick Test after completing service on the DTC's.
- If the continuous test passes (system pass) and a concern is still present, refer to Diagnosis By Symptom and check OASIS and TSB's for diagnostic concern. Diagnosis By Symptom
After On-Board Diagnostics
NOTE: The vehicle wiring harness, powertrain control module and non-transaxle sensors may affect transaxle operations. Service these concerns first.
After the On-Board Diagnostic procedures are completed, service all DTC's.
Begin with non-transaxle related DTC's, then service any transaxle related DTC's. Refer to the Diagnostic Trouble Code (DTC) Charts for information on Condition and Symptoms. 6 Speed Automatic Transaxle This chart will be helpful in referring to the correct manual(s) and to aid in diagnosing internal transaxle concerns and external non-transaxle inputs. The pinpoint tests are used in diagnosing electrical concerns of the transaxle. Make sure that the vehicle wiring harness and the powertrain control module are diagnosed as well. Refer to the Computers and Control Systems for diagnosing non-transaxle electronic components. The diagnostic routine hydraulic/mechanical charts will help in diagnosing internal transaxle concerns and external non-transaxle inputs.
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 Computers and Control Systems.
NOTE: If a concern still exists after electrical diagnosis has been carried out, refer to Diagnosis By Symptom. Diagnosis By Symptom
If DTC's appear while carrying out the on-board diagnostics, refer to the Diagnostic Trouble Code (DTC) Charts for the appropriate repair procedure. 6 Speed Automatic Transaxle Prior to entering pinpoint tests, refer to any TSB's and OASIS messages for transaxle concerns.
