A4LD 4R44E 5R55W [02-UP] Automatic Transmission Front Band S FLEX

When a band in the overdrive or intermediate position starts slipping, the drum surface and the band lining take the damage together, and a standard replacement that cannot handle the thermal load will fail again under the same conditions. This flex band carries a higher energy rating than a baseline replacement, which means it is built to absorb more heat and pressure during apply cycles without breaking down as quickly at the friction surface. It is a single-piece flex band designed for the overdrive and intermediate position in 4R44E, 5R55W, and A4LD automatic transmission units, covering applications from 1980 forward. The flex construction allows the band to seat evenly around the drum contour as the servo applies pressure, spreading the clamping load across a broader contact area instead of concentrating stress at the edges. That even contact is what keeps the lining from glazing prematurely on one side while the other side is still fresh. This part ships at approximately 1 lb and comes as a single band. There are no friction plates, steels, Automatic Transmission Filter, gaskets, or seals in this order. If your rebuild requires those components, they need to be sourced separately. Before placing the order, pull the transmission code directly from the unit and match it to 4R44E, 5R55W, or A4LD. Do not rely on the vehicle model or engine size alone to confirm fitment, since the same vehicle platform was paired with more than one transmission family across different production years. Confirming the actual unit code is the only reliable way to verify this band fits your job.

• A higher-energy flex band in the overdrive and intermediate position gives the unit more thermal capacity where band slippage typically starts, reducing the risk of early glazing or burn failure.
• This listing covers a single flex band only. No friction discs, steel plates, Automatic Transmission Filter, gaskets, or seals are included. If your job needs those parts, check your parts list before ordering.
• The flex design allows the band to conform more evenly across the drum surface during apply, distributing clamping load more consistently than a rigid band under the same servo pressure.
• One flex band, overdrive and intermediate position, higher-energy rating, approximately 1 lb shipped. No additional components are packed with this part.
• Before ordering, confirm the transmission code on the unit itself. This band fits 4R44E, 5R55W, and A4LD units. Cross-check the model and build year against your job sheet to avoid a return.
