Transmission Mount

Start with disconnecting the negative Battery Cable before securely raising the vehicle for transmission mount replacement. Remove the rear tire and wheel assemblies while also taking out the rear Shock Absorber lower mounting bolts together with the transaxle mount to Rear Crossmember nuts. Set up the j 42055 transmission support fixture (J 42055) on a transmission jack before securing it tightly to the transmission. Secure the transmission jack under the rear suspension crossmember so you can take out the retaining nuts with hand tools only. Carefully drop the Rear Crossmember 37 mm (1.5 inches) while removing the mount-to-differential bolts leading to the replacement part. The procedure begins with new transaxle mount installation followed by tightening transaxle mount to differential bolts at 50 nm (37 ft. Lbs.). When raising the rear suspension crossmember, carefully install the transaxle mount studs into the slots while tightening the new mounting nuts with hand tools up to 110 nm (81 ft. Lbs.). Take out the transmission jack that was mounted on the rear suspension crossmember before gently removing j 42055 and the transmission jack. Install the transaxle mount to rear suspension crossmember nuts, tightening them to 50 nm (37 ft. Lbs.)tighten the rear Shock Absorber lower mounting bolts to 220 nm (162 ft. Lbs.). Reinstall the rear wheel and tire units afterward the vehicle descent process completes while also reconnecting and tightening the negative cable bolt to 15 nm (11 ft. Lbs.). Finally, program the transmitters.

Disconnect the negative battery cable and raise the vehicle securely.
