This TSB is being republished in its entirety to include 1995 model year vehicles.
ISSUE:
Some customers may experience overdrive not engaging which is related to no torque converter clutch engagement in cold weather.
ACTION:
Inform the customer that the condition is normal. Refer to the following statement for specific details.
^
The torque converter clutch is designed not to engage until the transaxle has reached normal operating temperature. This is due to the higher
efficiency transaxle cooler used for the 3.2L applications.
^
If the vehicle has been parked for some time in cold weather, it may require several miles of driving to warm the transaxle.
^
It the vehicle had been previously driven and restarted while still warm, engagement of the torque converter clutch will occur much sooner.
^
Both conditions are normal and are intended to optimize both cold and warm weather driveability and fuel economy.
^
Torque converter clutch engagement may occur anywhere between 19°C (66°F) (3.O95 volts) and 49°C (120°F) (1.710 volts) Transmission Oil
Temperature (TOT) providing Engine Coolant Temperature (ECT) is greater than 54°C (130°F) (1.513 volts).
