When a U540E or A4LB1 automatic transmission starts slipping or shifts become inconsistent, worn friction material is often the direct cause, and replacing the correct module with a properly spec'd piece is the straightforward fix. This listing is for a single friction module designed for U540E and A4LB1 units in service from 2002 forward, not a kit, not a bundle, just the individual friction component for the technician who already has everything else on the bench.
The friction material in these units takes sustained heat and pressure through every shift cycle. When the surface degrades, clutch pack engagement becomes inconsistent and slippage follows. Fitting a replacement module that matches the stock dimensional and material requirements keeps pack end play correct and restores predictable engagement without introducing fitment problems.
This is a single piece. It does not include steel plates, an Automatic Transmission Filter, a band, seals, or any other rebuild components. If you are assembling a full overhaul, review your parts list and order the remaining items separately. The item weighs 5 lb.
Before placing your order, confirm the transmission identification code on your unit reads U540E or A4LB1, and that the vehicle application falls within the 2002-and-up production range. Transmission codes can appear on the case, the control valve body, or the repair order from the diagnostic stage. Matching the code before ordering avoids delays and return shipping.
