When the pump bushing in an automatic transmission wears down, shaft movement increases and seal life drops quickly. This listing covers a single pump bushing designed for 4F27E, FNR5, and FN4A-EL units built from 1999 forward, addressing one of the more common wear points found during a pump teardown.
The pump bushing sits at the interface between the pump body and the input shaft or stator shaft, depending on design. Once it wears past tolerance, the shaft rides off-center, which puts uneven pressure on the pump seals and can accelerate bore wear on the pump cover itself. Replacing this bushing during a rebuild, rather than reusing the stock, removes that variable from the repair.
This is a single piece. There are no seals, gaskets, clutch packs, steels, Automatic Transmission Filter, or other components included. If your rebuild calls for a broader set of parts, check the rest of the REMCO catalog for additional components covering these units. REMCO has worked in automatic transmission parts since 1991, and each item is pulled and verified individually before it ships.
Before placing an order, confirm that your unit carries one of these codes: 4F27E, FNR5, or FN4A-EL, and that the application year is 1999 or later. Unit codes are typically stamped on the case or listed on the build tag. If you are uncertain which unit is in the vehicle, cross-reference the code before buying. Returning a part because of a misidentified unit costs time on both sides.
- Restores proper pump shaft support in 4F27E, FNR5, and FN4A-EL units, helping prevent premature wear caused by a worn or damaged pump bushing.
- This listing is a single bushing only. It does not include any seals, gaskets, clutch discs, steels, Automatic Transmission Filter, or additional components. Review your parts list before ordering.
- Pump bushings control shaft movement inside the pump body. A worn bushing allows side-load that accelerates seal and bore wear, so replacing it during a rebuild addresses the root cause directly.
- One pump bushing. Unit weight: 1 lb. Assembled individually at the REMCO facility and verified against its item record before shipment.
- Before ordering, confirm your unit code matches 4F27E, FNR5, or FN4A-EL and that your application falls within the 1999-and-up range covered by this part.
