48RE [03-UP] Automatic Transmission Bushing Extension Housing

When the extension housing bushing wears out, the output shaft loses its support at the rear of the case, and that play shows up fast as vibration, seal failure, or fluid loss behind the tailhousing. This single bushing is cut for the extension housing position on A518, A618, 46RE, 47RH, and 48RE automatic transmission units produced from 2003 onward, so it addresses that specific wear point without requiring you to buy pieces you do not need.

This is an individual replacement piece, not a kit. The listing covers exactly one bushing. It does not include output shaft seals, extension housing gaskets, clutch discs, steels, Automatic Transmission Filter, or any band. If your repair also requires those components, they need to be sourced separately. Knowing that before you order avoids a second trip to the parts counter after teardown.

REMCO has worked with automatic transmission components since 1991. Each piece that leaves here is pulled by hand and checked against the order before it goes into the box, including single-piece orders like this one. The item ships at approximately 1 lb.

To confirm fit, match your transmission identification tag to one of the listed codes and verify the build year falls within the 2003-and-up range. If you are unsure of the code, check the tag on the transmission case before ordering, because no two of the covered units have identical housing dimensions at every point, and ordering by vehicle year alone is not enough to confirm the right bushing.

• This extension housing bushing addresses wear at the rear output of the unit, helping maintain shaft alignment and reduce fluid leaks at that point.
• This listing covers one bushing only. It does not include any seals, gaskets, clutch discs, steels, Automatic Transmission Filter, or band. Verify the exact part you need before ordering.
• The bushing is sized specifically for the extension housing position on A518, A618, 46RE, 47RH, and 48RE automatic transmission units built from 2003 forward, so it fits without modification.
• Contents: 1 extension housing bushing. Item ships at approximately 1 lb. Because this is a single piece, there is no kit packing list, but the part is pulled and checked individually before it ships.
• Before ordering, confirm your transmission code matches A518, A618, 46RE, 47RH, or 48RE and that your unit falls within the 2003-and-up build range to ensure this bushing corresponds to your application.
