When the extension housing bushing wears out, the output shaft begins to move off-center, which accelerates rear seal failure and leads to fluid loss at the back of the automatic transmission. This is a single replacement bushing designed for the extension housing on 48RE, 47RH, 46RE, A618, and A518 units built from 2003 and up.
Because this is one individual piece and not a kit, it fits situations where only this specific component needs replacement without purchasing a larger assembly of parts. The bushing installs into the rear of the extension housing and holds the output shaft in its correct position. Keeping that alignment tight is what allows the rear seal to seat properly and stay seated under operating conditions.
This listing contains exactly one extension housing bushing. There are no seals, gaskets, clutch plates, steels, Automatic Transmission Filters, bands, or any other components included. If your repair requires additional parts, those would need to be sourced separately.
Before placing an order, cross-reference the transmission code stamped on the unit, confirm the model year falls within the 2003-and-up range, and verify the output shaft diameter is consistent with these transmission families. The codes 48RE, 47RH, 46RE, A618, and A518 are closely related but not always interchangeable in every detail, so checking the actual unit code is the right step.
