Replacing the B-1-2 bushings and washer in a 45RFE or 545RFE automatic transmission is one of those steps that separates a rebuild that holds up from one that comes back with the same shift complaints. This set is built specifically for the B-1-2 location in these two units and is not a generic bushing assortment pulled from a bulk bin.

The B-1-2 circuit is load-bearing when it comes to pressure control and clutch apply in both the 45RFE and the 545RFE. When the bushings wear, end play open up, fluid bleeds past, and the transmission loses the firm apply it needs to shift cleanly. No amount of relearning or solenoid swapping corrects that. The fix is mechanical, and it starts here.

This is not a full rebuild kit. It does not include friction discs, steel plates, an Automatic Transmission Filter, bands, or seals. If your job calls for those items, they need to be sourced separately. Check your parts list against what is actually needed before placing the order.

Each set is assembled individually. The bushings and washer are counted and verified against the item listing, then packed with that listing inside the box so whoever opens it at the bench can confirm what arrived. This process has been part of how REMCO has operated since 1991.

Weight is 1 lb. Application covers 45RFE and 545RFE units, 1999 and up. Before ordering, pull the transmission code directly from the unit and confirm the year falls in that range. Ordering by vehicle model alone has caused mismatches in the past; the transmission code is the reliable check.

• Worn B-1-2 bushings and the washer behind them cause pressure loss and shift complaints that no solenoid calibration will fix -- replacing them addresses the source directly.
• This set covers bushings and washer only. It does not include friction discs, steels, Automatic Transmission Filter, gaskets, or seals. Verify the rest of your rebuild order before purchasing.
• The B-1-2 circuit sits at the core of shift feel in the 45RFE and 545RFE: sourcing the bushing set as a matched group means all clearances hold to the same spec at assembly.
• Contents: B-1-2 bushings and washer sized for the 45RFE and 545RFE automatic transmission. Shipped at 1 lb. Each piece is checked against the part listing before the box is sealed.
• Before ordering, confirm the transmission code stamped on your unit reads 45RFE or 545RFE and that the model year falls within the 1999-and-up range this set covers.
