A collapsed transmission mount lets the tail of the gearbox bounce on every shift and throttle transition. The J Replace OE style replacement transmission mount for the 1989 to 1998 Nissan 240SX is 30% stiffer than the stock rubber, holding the transmission firmly so the driveline stays aligned under load while retaining the factory mounting footprint.
All 1989 to 1998 Nissan 240SX, S13 and S14, with the KA24E, KA24DE or SR20DET engine.
This mount is a sensible upgrade during an SR20DET swap, a clutch job or any time the transmission is out, since the original mount has usually softened or torn by now. It is also the individual transmission mount from the J Replace reinforced engine and transmission mount kit, so it suits owners who already have fresh engine mounts and only need the rear.
Support the transmission with a jack, unbolt the crossmember, swap the mount and reinstall. Confirm the driveshaft angle and exhaust clearance are unchanged before final torque.
Note: These transmission mounts are intended for use in competition vehicles only, which may never be registered, licensed, or driven on public streets or highways.
