1998 Saturn SL2 L4-1.9L DOHC VIN 7SECTION Transmission Learn-In Procedure
If one of the repairs mentioned has been performed, then the adaptives should be reset using the Service Stall System (SSS) or using a Scan tool. 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. Warm up transaxle (fluid temperature above 45°C [113°F.]).
2. Perform 10 sets of upshift (1-2, 2-3, 3-4) at 30 percent throttle:
- For Double Overhead Cam (DOHC) (LL0) Engine
a. While coasting at 56 km/h (35 mph) slowly accelerate to half throttle to achieve a 4-3 downshift.
b. With selector in D3 while coasting at 32 km/h (20 mph) slowly accelerate to 75 percent throttle to achieve a 3-2 downshift.
Repeat both procedures five times.
- For Single Overhead Camshaft (SOHC) (L24) Engine
a. While coasting at 64 km/h (40 mph) slowly accelerate to half throttle to achieve a 4-3 downshift.
b. With selector in D3 while coasting at 48 km/h (30 mph) slowly accelerate to one half throttle to achieve a 3-2 downshift.
Repeat both procedures five times.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
