When a 6HP19 or 6HP21 automatic transmission starts slipping or failing to engage cleanly, the friction module is one of the first components a technician pulls for inspection, and having the correct replacement on hand avoids the downtime that comes with back-ordering individual parts. This listing covers a single friction module built to fit both the 6HP19 and 6HP21 unit codes, so shops that service either variant can stock one reference number instead of two.
The part ships as a standalone piece. There are no seals, no gaskets, no Automatic Transmission Filter, no steel plates, and no additional hardware in the box. If your repair also requires those components, they need to be sourced separately before the job starts. The weight of this unit is 2 lb, which is consistent with the stock assembly and is a useful cross-check if you are comparing against a core you pulled from the vehicle.
REMCO has been working in automatic transmission parts since 1991. Each order is put together individually at the warehouse, checked against its part record before it ships, and the box includes a part list so the receiving technician can confirm what arrived without guessing.
Before placing the order, locate the unit code stamped directly on the transmission case and confirm it reads 6HP19 or 6HP21. Also verify the vehicle production year falls within the 2000-and-up range this part covers. Ordering against an incorrect unit code is the most common reason for a return on single-piece components like this one, and a quick check of the case stamp takes less than a minute.
