Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery before beginning work to prevent electrical shorts.

2. Fluid Change

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Remove the transmission pan bolts using a socket set.
3. Carefully lower the pan, allowing old fluid to drain into a suitable container.
4. Remove the old transmission filter and replace it with a new one.
5. Clean the transmission pan thoroughly and replace the gasket with a new one.
6. Reinstall the pan and torque the bolts to the manufacturer’s specifications (typically 8-10 ft-lbs).

3. Throttle Position Sensor (TPS) Inspection

Sub-steps:
1. Locate the TPS on the throttle body.
2. Disconnect the electrical connector and remove the TPS from its mounting.
3. Inspect the TPS for wear or damage. Replace if necessary.
4. Reinstall the TPS and reconnect the electrical connector.

4. Transmission Control Module (TCM) Reset

Sub-steps:
1. Reconnect the battery.
2. Start the vehicle and allow it to idle for a few minutes.
3. Drive the vehicle under various conditions to allow the TCM to relearn shift patterns.
