Transmission Learn-In Procedure

If one of the repairs mentioned under Resetting Adaptive Parameters has been performed, then the adaptives should be reset using the Saturn Stall System.

The Saturn Stall System is used to set the adaptive parameters to a neutral value. Otherwise, additional road testing may be required to allow the PCM/TC to "learn" the new shift timing and points. Also, the vehicle must be driven, preferably on a highway, according to the following steps. By following these steps, the adaptives will be properly learned prior to returning the vehicle to the customer.


1. Place shift mode switch in the normal mode position.

2. Warm up transaxle (oil temp. above 45°C [113°F]).

3. Perform 10 sets of upshift (1-2, 2-3, 3-4) at 30% throttle:

4. While coasting at 56 km/h (35 mph) slowly accelerate to half throttle to achieve a 4-3 downshift.

5. With selector in D3 while coasting at 32 km/h (20 mph) slowly accelerate to 75% throttle to achieve a 3-2 downshift.

6. Repeat steps 4 and 5 at least five times.
