Disconnect the battery to prevent any electrical shorts.

2. Fluid Change

Sub-steps:
1. Remove the transmission drain plug using a socket set and drain the old fluid into a suitable container.
2. Replace the transmission filter if applicable (access may require removal of the transmission pan).
3. Clean the transmission pan and magnet, removing any debris.
4. Reinstall the transmission pan with a new gasket and torque the bolts to the manufacturer’s specifications.
5. Refill the transmission with the correct type of fluid (refer to the owner’s manual for specifications).

3. Solenoid Replacement (if needed)

Sub-steps:
1. Remove the transmission pan again to access the solenoids.
2. Disconnect the wiring harness from the solenoids.
3. Remove the old solenoids using a socket set.
4. Install new solenoids and reconnect the wiring harness.
5. Reinstall the transmission pan and torque the bolts to the specified value.

4. TCM Reset

Sub-steps:
1. Reconnect the battery.
2. Use an OBD-II scanner to reset the transmission control module settings.
3. Clear any stored fault codes.
