Worn bushings and washers in the B-1-2 circuit are a known source of shift feel complaints and accelerated internal damage in 10-speed automatic transmission units; replacing them as a group rather than hunting pieces individually saves bench time and reduces the risk of missing a worn component. This 11-piece set covers the B-1-2 bushings and washers for 10L80 and 10R80 units built from 2017 to current production, and every piece in it is pulled by hand at REMCO before the box closes.REMCO has been working in automatic transmission parts since 1991, and the way these sets are assembled has not changed: each component is counted against the part list that ships inside the box, so the technician at the bench can verify the count before the job starts. There are no pre-packaged bulk lots here; the 11 pieces in this set are selected one by one.What this set does not cover is equally important to know before ordering: friction discs, steel reaction plates, filter, and band are not included. If your teardown shows those components need replacement, source them separately. Ordering without checking that detail is the most common reason for a return, and a quick look at your parts list before you buy avoids the delay.Applies to 10L80 and 10R80 units, model years 2017 through current. Shipped weight is 1 lb. Confirm your unit identification code and production year match before placing the order. Fits the B-1-2 apply circuit in 10L80 and 10R80 10-speed units, addressing worn or loose bushings and washers that cause shift complaints and internal wear. This set does not include friction discs, steel plates, filter, or band; check your full parts list before ordering so nothing is missing from your rebuild. Eleven individual bushings and washers sized specifically for the B-1-2 circuit; each piece is pulled from inventory and hand-counted before the box is sealed. Contents: 11 pieces total covering B-1-2 bushings and washers for 10L80 and 10R80 units; shipped weight 1 lb. Before ordering, confirm your unit identification code is 10L80 or 10R80 and that your application falls within the 2017-to-current production range.
