C4 C5 [64-UP] Automatic Transmission Bushing Extension Housing (1.500id)

Replacing a worn extension housing bushing in a C4 or C5 automatic transmission is a straightforward step that helps avoid output shaft wobble, protects the tailshaft seal from premature failure, and keeps fluid where it belongs. This is the babbitt-material bushing seated at the extension housing, with a 1.500 in inside diameter, sized for units produced from 1964 through 1986.

Babbitt is the correct material choice for this location. Unlike harder alloys, babbitt conforms gradually to the output shaft surface during initial run-in, reducing the risk of shaft scoring when the fit is slightly loose from wear. It is not a substitute or an upgrade -- it is what belongs in this position on these units.

This listing covers a single bushing. There is no seal, no output shaft, no gasket, and no additional hardware included. A technician rebuilding the rear of one of these transmissions will typically need the tailshaft seal as a separate purchase; that part is not here.

REMCO has been working with automatic transmission parts since 1991. Each order is assembled by hand at the warehouse, checked against its part record before it ships, and the contents are identified on the box. For a single piece like this one, that means you can confirm what you received the moment the package opens.

Before placing the order, verify the transmission identification code -- C4 or C5 -- and confirm the build year falls in the 1964 to 1986 range. Also measure or confirm the housing bore accepts a 1.500 in outside-diameter bushing. If the unit has been repaired before and a non-standard bushing was installed, the bore may have been modified.

• Worn extension housing bushings cause rear shaft play, fluid leaks at the tailshaft seal, and accelerated seal wear -- replacing this bushing directly addresses those failure points.
• This listing is for the extension housing bushing only. It does not include the tailshaft seal, output shaft, or any other components. Verify what else you need before ordering.
• Babbitt material is the spec for this position in C4 and C5 units: softer than bronze, it conforms to shaft surface without scoring the output shaft during break-in or normal operation.
• One extension housing bushing, 1.500 in inside diameter, babbitt construction, weight 1 lb. Single piece, no kit.
• Before ordering, confirm your transmission code is C4 or C5 and that the unit was built between 1964 and 1986. Inside diameter of your housing bore should match 1.500 in.
