Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and securely elevated with jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Drain Fluid
- Place a drain pan under the transmission pan.
- Remove the pan bolts with a socket set and carefully lower the pan.
Inspect Fluid
- Inspect the transmission fluid for discoloration (dark brown or burnt smell indicates contamination).
Replace Fluid
- Install a new gasket on the transmission pan.
- Refill with manufacturer-recommended transmission fluid using a funnel.
- Torque the pan bolts to the manufacturer's specifications (typically around 10-15 Nm).

3. Replace Transmission Filter

Remove Old Filter
- Locate the transmission filter (may require removing the pan).
- Unclip or unscrew the old filter and remove it from the transmission.
Install New Filter
- Position the new filter in the same location, ensuring it clicks into place or is secured properly.

4. Inspect and Repair Transmission Control Module (if necessary)

Check TCM Connections
- Inspect the wiring and connectors for damage or corrosion.
Reprogram TCM
- If needed, use a diagnostic tool to upload the latest software updates to the TCM.

5. Test Drive

Reconnect the battery terminal.
Start the engine, allow it to warm up, and check for leaks around the transmission pan.
Perform a test drive to ensure smooth shifting and monitor for any return of symptoms.
