When the pump bushing in an A500 or A904 unit is worn, the pump loses the tight fit it needs to move fluid consistently, and no amount of other rebuild work fixes that root cause. This listing covers a single bronze pump bushing for those two units, nothing more, and that focus is exactly what makes it useful: you are ordering the specific piece the pump bore needs, not a kit with parts you do not require.
Bronze is the right material here because it machines to close tolerances and resists the heat generated inside an automatic transmission pump during normal operation. It does not deform under load the way softer materials can, which means the running fit between the bushing and the shaft stays within the range the pump was designed to work in. That mechanical relationship drives everything downstream: line pressure, clutch apply, shift timing.
REMCO has been working in automatic transmission parts since 1991. This bushing is pulled from open inventory and checked against the part number before it is packed. The box includes a part number reference so you can confirm what you received before the car goes on the lift.
This is a single piece, weighing approximately 1 lb. No seals, no gaskets, no other components ship with it. If your rebuild calls for those items, they need to be sourced separately.
Before placing the order, verify that your unit is coded A500 or A904 and that the vehicle was built 1968 or later. Unit codes on these transmissions are stamped on the case; cross-check that stamp against this listing before you buy.
- Fits A500 and A904 automatic transmission units built from 1968 forward, covering pump bushing replacement in rebuild or repair service.
- This listing is a single bushing only. No seals, no gaskets, no other hardware are included. Check your parts list before ordering to avoid a second purchase.
- Bronze material holds its shape under the heat and load cycles inside the pump bore, helping the pump maintain consistent fluid movement through the rebuild life.
- One bronze pump bushing, approximately 1 lb shipped. Pulled from open stock at the REMCO warehouse and verified against the part number before it leaves.
- Before ordering, confirm your unit code is A500 or A904 and that your application falls within the 1968-and-up range. One wrong digit in the unit code means the wrong part.
