Honda Civic Coupe 2006-2011 1.8L Auto Trans Mount Kit 4-Piece

A four-piece mount set for the 2006-2011 Honda Civic coupe with the 1.8L four-cylinder and the 5-speed automatic. It includes the hydraulic right engine mount, the left automatic transmission mount, the right upper torque strut mount and the rear lower torque strut mount. It crosses to A4534, A4543 and A4546 and replaces Honda numbers including 50820-SVA-A05, 50850-SNA-A01, 50880-SNA-A81 and 50890-SNA-A81.

The hydraulic right-side mount on the 8th-generation Civic is a known failure. Once it collapses the engine drops, you get a heavy vibration in drive at a stop, and a thunk shifting from park into drive or reverse. The left transmission mount and the lower rear strut follow close behind. A torn mount can pass for a harsh 1-2 shift or a transmission engagement problem, so check the mounts before condemning the automatic.

Coupe with automatic transmission only. The sedan and the manual cars use different mounts.

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.
