If a specific relearn procedure is not available, the following procedure may be used on vehicles equiped with automatic transmission:
1/ Set the parking brake and start the engine in P or N. Allow the engine to warm up untill the electric cooling fan cycles on.
2/Allow the vehicle to idle for about a minute in N possition, then move the gear selector into the D position and allow it to idle in gear for one minute.
3 Road test the vehicle. Accelerate at normal trottle openings( 20% - 50%) until the vehicle shifts into top gear.
4 Then maintain a cruising speed with light-to-medium throttle.
5/Decelarate to a stop, make sure you allow the transmission to downshift, and use the brakes to bring the vehicle to a stop.
6/ If driveability problem still exists, repeat the sequence.
* A vehicle computer may memorizes a vehicle's operation patterns for 40 or more key starts.
Ask your technician if there is a specific computer relearn procedure for your vehicle.
