- Allow the fluid to drain completely into a suitable container.
Replace Filter:
- Remove the transmission pan bolts using a socket set.
- Carefully detach the transmission pan and remove the old filter.
- Clean the pan and install the new filter, ensuring it seats properly.
Install New Fluid:
- Reattach the transmission pan with a new gasket and torque the bolts to manufacturer specifications.
- Using a transmission fluid pump, fill the transmission with new, manufacturer-recommended fluid until it reaches the proper level.

3. Check Transmission Solenoids

Remove Solenoids:
- Locate the transmission solenoids based on the vehicle service manual.
- Disconnect electrical connectors and remove the solenoids using a socket set.
Test Solenoids:
- Use a multimeter to check the resistance of each solenoid against specifications in the service manual.
- Replace any solenoids that do not meet the specifications.

4. Inspect and Repair Wiring Harness

Inspect for Damage:
