4L80E [91-UP] Automatic Transmission Bushing 1000 Extension Housing Long

When the extension housing bushing wears, the output shaft gains side play that accelerates seal wear and leads to fluid loss at the rear of the unit. This is a single replacement bushing cut to 1.000 inch in length for the extension housing of 4L80E and 4L85E automatic transmission units built from 1991 through 2003.

The 1.000 inch length is the figure that matters most here. A bushing that is too short leaves part of the bore unsupported, and one that is too long will not seat correctly. This piece is dimensioned to fill the housing bore as the stock did, restoring the bearing surface the output shaft rides against.

This is a single bushing, not a kit. There are no seals, snap rings, gaskets, or other components in this listing. If your repair also calls for a rear seal or output shaft seal, those need to be sourced separately.

Before placing the order, confirm two things: that the transmission code is either 4L80E or 4L85E, and that the build year falls within the 1991 to 2003 range. Also inspect the housing bore itself. If the bore has galling or is out of round beyond what a new bushing can take up, the housing will need to be repaired or replaced regardless of the bushing condition. REMCO has been working in automatic transmission parts since 1991 and each piece is checked against its item record before it ships.

• Replacing a worn extension housing bushing stops shaft slop and leak paths that develop when the bore wears out of round over time.
• This listing covers one bushing only. It does not include any seals, rings, gaskets, or other drivetrain components, so confirm this is the exact piece you need before ordering.
• At 1.000 inch in length, this bushing matches the stock depth of the extension housing bore on 4L80E and 4L85E units, keeping the tailshaft centered without modification.
• One extension housing bushing, 1.000 in. long. Item weight: 1 lb.
• Before ordering, verify your transmission code is 4L80E or 4L85E and that the unit was built between 1991 and 2003. Check the housing bore for damage that a bushing alone cannot correct.
