Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid pump, torque wrench, multimeter, transmission fluid.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical issues during repairs.

2. Fluid Change

Drain Transmission Fluid
- Place a drain pan beneath the transmission pan.
- Remove the transmission pan bolts using a socket set.
- Carefully lower the pan and allow fluid to drain completely.
Replace Transmission Filter
- Remove the old filter from the transmission.
- Clean the filter mounting surface thoroughly.
- Install a new transmission filter, ensuring it is seated properly.
Reinstall Transmission Pan
- Clean the pan and inspect for damage.
- Apply a new gasket or sealant (as recommended by the manufacturer).
- Reattach the pan to the transmission and torque bolts to the manufacturer’s specifications.
Refill Transmission Fluid
- Use a fluid pump to refill the transmission with the recommended type of fluid (check the owner’s manual for specifications).
- Start the engine and allow it to idle; shift through all gears to circulate the new fluid.

3. TCM Reprogramming (if necessary)

Reprogram Control Module
- Connect the OBD-II scanner to the vehicle.
- Follow the scanner's instructions to access the transmission control module.
- Update or reset the TCM settings as needed.
