5R55N [99-UP] Automatic Transmission Bushing Pump S

When pump end play in the 5R55N grow beyond spec, pressure drops and shift feel follows, and replacing the pump bushing is one of the first mechanical corrections a transmission technician reaches for. This listing covers that single piece: one pump bushing, specific to the 5R55N automatic transmission, covering applications from 1999 forward.

The 5R55N shares a family name with the 5R55S and 5R55W but the pump bushing is not interchangeable across those variants, so confirming you have the N build before ordering is the most important step in the process. If you are not certain which member of the 5R55 family is in the vehicle, check the tag on the unit or cross your existing part number before adding this to the cart.

This is not a kit. There are no seals, no friction discs, no steels, no Automatic Transmission Filter, and no band included. The listing is for one bushing. That is intentional: many technicians rebuilding a 5R55N already have a seal kit on order or on hand and need only the bushing to complete the pump work. Ordering a single piece here means you are not duplicating parts you already purchased elsewhere.

REMCO has been working in automatic transmission parts since 1991. Each piece that leaves here is pulled individually and verified against its part record before it is packed. A part list is included in the box so you can confirm what arrived matches what was ordered, which matters when you are tracking parts across a full rebuild. Item weight is 1 lb.

• A single pump bushing sized for the 5R55N unit covers the pump wear point that causes pressure loss and delayed engagement if left unaddressed.
• This listing is for one bushing only. It does not include seals, o-rings, friction discs, steels, Automatic Transmission Filter, or any other component. Verify your parts list before ordering.
• The 5R55N pump bushing is a standalone piece, not part of a larger kit, which means you order exactly what you need without paying for parts you already have on the bench.
• Contents: 1 pump bushing for the 5R55N transmission. Item weight: 1 lb. Each piece is checked against its part record at the time it is pulled and packed here at REMCO.
• Before ordering, confirm your unit is the 5R55N and not a related member of the 5R55 family such as the 5R55S or 5R55W. The pump bushing differs across variants.
