4L80E [97-UP] Automatic Transmission Bushing Pump (Babbit) (wide.700)

When the pump bushing wears down in a 4L80E or 4L85E automatic transmission, the drive shaft loses its radial support at the pump housing, and everything downstream feels it: pressure regulation becomes inconsistent, fluid bypass increases, and the pump itself starts wearing faster than it should. This is a single babbitt-lined pump bushing, wide at .700 inches, designed for 4L80E and 4L85E units from 1997 forward, and it addresses that failure point directly.

Babbitt is a softer bearing alloy that has been used in transmission bushings for decades precisely because it wears against the shaft rather than into it. As the bushing seats over time, it conforms slightly to the shaft surface, which reduces the scoring risk you get with harder materials. At .700 inches wide, this bushing fits the pump bore dimension on these units -- not a narrower version, not an aftermarket substitute sized for a different application.

This listing covers one bushing, nothing else. There are no seals, no gaskets, no frictions, no Automatic Transmission Filter, and no additional hardware included. If your rebuild calls for a complete overhaul kit or a seal kit, those are separate purchases. Check your parts breakdown against what you actually need before ordering.

At REMCO, which has been working in automatic transmission parts since 1991, each item is pulled and packaged individually here -- not shipped from a bulk pre-pack. The box includes an itemized parts list so you can verify what you received before you open anything.

Confirm two things before you order: that your transmission is a 4L80E or 4L85E built 1997 or later, and that the stock pump bushing in your unit measures .700 wide. If the dimension on the worn part does not match, this bushing will not fit correctly. SKU for this item is.

• A worn pump bushing lets the pump shaft walk off-center, causing pressure loss and accelerated wear on surrounding components -- this babbitt-lined replacement restores proper shaft alignment.
• This listing is for one pump bushing only. It does not include seals, rings, gaskets, frictions, steels, Automatic Transmission Filter, or any other rebuild components -- verify your parts list before ordering.
• The babbitt lining on this bushing provides a softer bearing surface that conforms gradually to the shaft without scoring it, which matters on a component that sees constant fluid pressure from the moment the engine starts.
• One pump bushing, babbitt material, wide at .700 inches. Packaged individually. Item weight: 1 lb. SKU, catalogued under the 4L80E bushing line.
• Before ordering, confirm your unit is a 4L80E or 4L85E built 1997 or later and that the pump bushing in your application matches the .700 wide dimension -- measure the stock before pulling the trigger.
