When the B-1-2 bushing surfaces and thrust washer in a 4T40E or 4T45E wear beyond tolerance, internal looseness and inconsistent shift behavior follow. This set addresses exactly that circuit, supplying the bushings and washer sized for the B-1-2 area of those two automatic transmission models without bundling unrelated parts you may already have on the bench.The 4T40E and 4T45E share a close family relationship, and this set covers both units built from 1995 forward. Because the components are specific to the B-1-2 location, a technician working a full rebuild should cross this set against the rest of the parts already pulled, confirming nothing overlaps and nothing is missing from other circuits.At the REMCO facility, open since 1991 in automatic transmissions, each order is assembled by hand and verified against a printed parts list that ships inside the box. That list lets the installer confirm every bushing and the washer are present before the transmission goes back together, avoiding a disassembly later over a missing piece.This set does not include friction discs, steel plates, filter, band, or any solenoid. If your job requires those components, they need to be sourced separately. The set weighs 1 lb.Before placing the order, verify the code stamped on the transmission case matches 4T40E or 4T45E, confirm the model year falls at 1995 or later, and check that the B-1-2 bushings and washer are the specific items your inspection identified as needing replacement. Addresses worn or damaged B-1-2 bushings and thrust washer that cause internal play, noise, or shift irregularities in 4T40E and 4T45E units built from 1995 onward. This set does NOT include friction discs, steel plates, filter, bands, or solenoids. Review your rebuild parts list carefully before purchasing to avoid unnecessary returns. Specific to the B-1-2 area of the 4T40E and 4T45E: the bushings and washer in this set target the fit and movement tolerances of that circuit, not the transmission as a whole. Contents: B-1-2 bushings and thrust washer matched to 4T40E and 4T45E specifications. Each set is assembled and checked against its own parts list at the REMCO facility. Weight: 1 lb. Before ordering, confirm the exact transmission code stamped on the unit, the model year, and that your application falls within the 4T40E or 4T45E family built from 1995 up.
