Highlander Hybrid 2006-2007 3.3L Engine and Trans Mount Kit

A three-piece mount set for the 2006-2007 Toyota Highlander Hybrid (base and Limited) and the 2006-2008 Lexus RX400h, both with the 3.3L V6 hybrid drivetrain. It includes the hydraulic front engine mount, the solid front right engine torque strut mount, and the hydraulic transmission mount with its mounting bracket. It crosses to A4207, A4242 and A62080HY and replaces Toyota numbers including 12361-20230, 12363-20130 and 12372-0A040.

The hybrid drivetrain starts and stops the gas engine constantly, and every restart shakes the mounts. When the hydraulic mounts leak down you feel a hard shudder each time the engine kicks on, a clunk when pulling away in EV mode, and more vibration through the floor at idle. Owners often chase that as a transaxle or inverter issue. A fresh set with the bracket already on the transmission mount puts the drivetrain back where it belongs.

Hybrid 3.3L models only. Compare each mount with the original before installing.

On the job: support the engine from above or with a jack and a block of wood under the oil pan before any mount comes out. Change one mount at a time, leave the through-bolts snug until every mount in the set is in, then let the drivetrain settle at rest and torque everything. Tightening a mount while the engine is jacked sideways preloads the rubber, and a preloaded mount tears early.
