When the B-1-2 circuit shows wear in a 4L40E, 5L40E, ON10, or 5L50E automatic transmission, having the correct bushing and washer set ready means the job moves forward without waiting on individual pieces to come in separately. What sets this part apart is that it is a dedicated B-1-2 bushing and washer combination sized for these specific units, covering applications from 1999 forward, so there is no guessing about fitment when the transmission code on the unit matches one of those four designations.
This is not a broad overhaul kit. It does not include friction discs, steel plates, an Automatic Transmission Filter, bands, or any gaskets or seals beyond what belongs to the B-1-2 bushing and washer set itself. If your rebuild calls for those components, they need to be sourced separately. That distinction matters before the order is placed, not after the box arrives.
Each set is assembled at the REMCO facility, where components are brought together individually and checked against the parts list before packaging. That list ships inside the box, giving the technician a straightforward way to verify the contents at the bench. REMCO has worked in automatic transmission parts since 1991, and that background shapes how these sets are put together.
The packaged weight is 1 lb. Compatible units are 4L40E, 5L40E, ON10, and 5L50E, 1999 and up. Confirm the code on the transmission case and the vehicle year before placing the order.
