- Wipe it clean, then reinsert and remove to check the fluid level.
Drain Old Transmission Fluid
- Place a drain pan underneath the transmission pan.
- Remove the transmission pan bolts using a socket set.
- Carefully lower the pan to drain the fluid and inspect for metal shavings.
Replace Transmission Fluid
- Replace the transmission filter (if applicable).
- Install a new gasket on the transmission pan and reattach it.
- Fill the transmission with the manufacturer-recommended fluid type through the dipstick tube.

3. Inspect and Replace Transmission Control Module (if necessary)

Remove the TCM
- Locate the transmission control module, usually found near the transmission.
- Disconnect the electrical connectors and remove the mounting bolts.
Install the New TCM
- Position the new TCM and secure it with bolts.
- Reconnect the electrical connectors.

4. Test Drive

Reconnect the battery and start the vehicle.
Conduct a test drive to ensure proper shifting and that the slipping issue is resolved.
