Insert a large screwdriver or prybar into the space between the transmission extension and the crossmember and pry up, ensuring the transmission does not spread excessively away from the insulator by checking for movement of the mount. To replace, support the transmission with a jack and remove the two nuts attaching the insulator to the crossmember along with the two bolts attaching the insulator to the transmission. Raise the transmission and remove the insulator, then proceed with installation in the reverse order of removal.
