8. Refill the transmission with the correct type of fluid (consult the owner’s manual for specifications).

3. Inspect and Replace Transmission Mounts (if needed)

Raise the vehicle and secure it on jack stands.
Locate the transmission mounts and visually inspect for cracks or wear.
If damaged, remove the bolts securing the old mounts using a socket set.
