- Place a jack under the transmission to support it.
- Remove the bolts securing the old mounts to the transmission and the frame.
- Install the new mounts and torque to specifications.
- Lower the vehicle and test drive to check for improvement in shifting.

Replacing Transmission Solenoids

Tools Required: Basic hand tools, new solenoids.
Procedure:
- Disconnect the battery to prevent electrical shorts.
- Remove necessary components to access the valve body.
