Diagnostic Steps

1
Check for Diagnostic Trouble Codes (DTCs) using an OBD-II scanner to ensure no underlying issues exist.
2
Verify Transmission Fluid Level and Condition by checking the dipstick and inspecting the fluid for contamination or burnt smell.
3
Inspect Wiring and Connectors for damage or corrosion related to the transmission control module.

Solution

1. Preparation

Tools Required: OBD-II scanner, basic hand tools (socket set, wrench set), transmission fluid dipstick.
Make sure the vehicle is parked on a level surface.
Ensure the engine is off and the keys are removed from the ignition.

2. Resetting the Adaptive Learning

Reconnect the Battery:
- Disconnect the negative terminal of the battery and wait for at least 15 minutes to reset the engine control module (ECM).
- Reconnect the negative terminal and ensure a secure connection.
Perform a Transmission Reset:
- Start the vehicle and allow it to idle for a few minutes without touching the accelerator.
- Shift the transmission through all gears (Park, Reverse, Neutral, Drive) slowly, pausing for 5-10 seconds in each gear to allow the transmission control module (TCM) to relearn the adaptives.
Test Drive:
- Drive the vehicle under various conditions (light acceleration, moderate acceleration, and deceleration) to allow the transmission to adapt to the driving style.
- Monitor shifting behavior during the test drive.

3. Final Checks

After the test drive, recheck for any DTCs to ensure no new codes have appeared.
If necessary, perform a fluid change if the condition of the transmission fluid was questionable during the inspection.
