Automatic Transmission Bushing 5212223

When the extension housing bushing wears down, the output shaft gains radial play that puts stress on the rear seal and allows fluid to work past it over time. Replacing this single bushing restores the close running fit the shaft needs at that location, and it addresses the root cause rather than just swapping the seal again.

This listing is for the extension housing bushing used in A404, A604, and A606 automatic transmission units, covering applications from 1978 forward. It is a single piece, not a kit. There are no seals, gaskets, thrust washers, or overhaul components included here, so if your job requires those parts as well, they will need to be sourced separately.

The bushing fits the bore at the extension housing where the output shaft exits the automatic transmission case. A worn bushing at this point allows the shaft to move off-center under load, which accelerates seal wear and can introduce vibration in the driveline. Fitting a correctly sized replacement stops that movement and lets the seal do its job.

REMCO has worked in automatic transmission parts since 1991. Each order is assembled individually and checked against its part record before it ships. The package includes a parts list so you can verify what arrived before the job starts.

Before placing the order, confirm the transmission code on the unit is A404, A604, or A606, and that the vehicle year falls within the 1978-and-up range. If you are unsure of the code, check the transmission identification tag before ordering.

• This extension housing bushing addresses shaft wear and play at the tail end of the unit, helping maintain proper alignment and reducing output shaft movement that leads to seal failure and fluid loss.
• This listing covers the extension housing bushing only. It does not include any seals, gaskets, thrust washers, overhaul components, or any other parts. Review your parts list before ordering to avoid a return.
• The bushing is selected to fit the extension housing bore of A404, A604, and A606 units. Replacing a worn bushing at this location restores the close fit the output shaft needs to run without excessive radial movement.
• Contents: one extension housing bushing. Article weight: 1 lb. Each unit is packed and cross-checked against its part record before leaving the facility.
• Before ordering, confirm the transmission code on the unit matches A404, A604, or A606, and verify the model year falls within the 1978-and-up range this bushing covers.
