Solution

1. Preparation

Ensure the vehicle is on a level surface and securely lifted if necessary.
Disconnect the battery to prevent any electrical issues during the repair process.

2. Fluid Change

Sub-steps:
1. Remove the transmission fluid pan by unscrewing the bolts using a socket set.
2. Allow the old fluid to drain completely into a suitable container.
3. Replace the transmission filter if applicable (remove the old filter and install a new one).
4. Clean the transmission pan and replace the gasket.
5. Reinstall the pan and tighten the bolts to the manufacturer’s specified torque (check vehicle specifications for proper values).
6. Refill the transmission with the manufacturer-recommended fluid type through the dipstick tube.

3. Electrical Inspection

Sub-steps:
1. Reconnect the battery and inspect the transmission control module (TCM) connections.
2. Use a multimeter to test the voltage at the TCM connector.
3. If any wiring is damaged, repair or replace the wiring as needed.

4. Test Drive and Adjustments

Sub-steps:
1. Start the engine and let it reach operating temperature.
2. Shift through all gears to ensure smooth operation.
3. If issues persist, consider resetting the TCM or reprogramming it with a diagnostic tool.
