Honda Odyssey 1999-2004 3.5L Auto Transmission Mount Kit

The 1999-2004 Odyssey is hard on its transmission already, and bad mounts make a healthy one feel broken. A worn rear left transmission mount lets the transaxle move under load, which feels like a clunk when you shift into gear, a jerk on and off the gas, and a vibration in the floor at idle in drive. The front hydraulic mount with the vacuum port loses its damping and passes every engine shake into the van.

This three-piece kit includes the right engine mount, the front engine mount (hydraulic, with vacuum port), and the rear left automatic transmission mount. It fits the 1999-2004 Honda Odyssey 3.5L V6 and the 2000-2001 Acura TL 3.2L V6, automatic transmission only. Cross references include A4519HY, A6552, A6579, EM8974, EM8986, EM9441 and Honda 50800-S0X-A03, 50820-S0X-A01, 50806-S0K-A80, 50806-S87-A80.

Before you condemn the transmission for a harsh engagement, check the mounts: hold the brake at idle, shift from drive to reverse, and watch for the engine rocking or lifting. On the front hydraulic mount, look for fluid weeping and a cracked vacuum line. Support the engine from below and change one mount at a time.
