d. Refill Transmission Fluid:
- Use a fluid pump to refill the transmission with the correct type and amount of fluid as specified in the owner’s manual.

3. Inspect and Replace Transmission Components

a. Inspect Solenoids:
- Remove the transmission access cover to access solenoids.
- Test solenoids with a multimeter and replace any that are faulty.
b. Inspect Wiring and Connectors:
- Repair or replace any damaged wiring or corroded connectors.
c. Reassemble Components:
- Reinstall the transmission pan and ensure all bolts are torqued to the specified value.
