400 [64-UP] bushing kit Automatic transmission

Key features

• Addresses wear in the B-1-2 circuit by replacing the bushings and washer that keep shaft alignment and end-play within spec, reducing internal leak paths.
• This listing does NOT include clutch packs, steels, sealing rings, gaskets, Automatic Transmission Filter, or band. Review your rebuild checklist before ordering to confirm this is the part you need.
• The B-1-2 bushing and washer set targets a specific failure zone in the TH400 and 3L80 valve body and drum area, letting the rebuilder source exactly what wore without buying a full overhaul kit.
• Kit contains the bushings and washer for the B-1-2 application. Shipped weight is 1 lb. Each unit is verified against its part list before the box is sealed.
• Before ordering, confirm your unit is a TH400 or 3L80 and cross your application year against the 1964-and-up range. Unit code on the case or tag is the reliable check.

When the B-1-2 area of a TH400 or 3L80 shows end-play problems or alignment wear, replacing only the bushings and washer in that circuit is the direct fix, and this set is assembled specifically for that job. Unlike a full overhaul kit, this listing covers a single assembly group, so the rebuilder is not paying for components that are still serviceable. The TH400, also coded 3L80, is a three-speed automatic transmission produced from 1964 onward and still found in heavy-duty and performance applications today. Bushing wear in the B-1-2 area can cause shaft movement, internal fluid loss between circuits, and inconsistent clutch apply. Catching and correcting that wear with the correct bushings and washer keeps end play where the stock design intended them. This set was put together at the REMCO facility, piece by piece, and checked against its part list before shipping. The box includes that list so the technician can confirm receipt before the unit goes on the bench. REMCO has been working in automatic transmission parts since 1991, and that experience shows in how each order is assembled and verified. What this listing does not cover: clutch friction discs, steels, sealing rings,
