How to Change a Transmission Mount

This article will step you through the removal and installation of a transmission mount.

Using a Poly mount is recommended. However it can cause more vibrations to be transferred to the car. Additional complications can arise with a poly mount due to its size being slightly out of spec.

Further conflicts can occur with sub-frame connectors and the poly mount.

After doing one tranny mount, doing it in the future shouldn’t take more than 15 minutes.

  1. Raise and support the car with jack stands.
  2. Remove the 15mm nut from the tranny mount stud.
  3. Use a 2×4 at least the width of the transmission pan on top of your jack and raise the transmission a few inches.
  4. Remove the two 14mm bolts from the mount to the transmission.
  5. Remove the mount, if it can’t be removed raise the transmission higher and try again.
  6. Install the new mount using the original 14mm bolts to the transmission and either the supplied cross member to mount bolts or the original 15mm bolt.
  7. Torque the bolts to spec.
  8. Return the car to the ground and go for a drive.
