TH400 4L80E [64-UP] Automatic Transmission Rear Band Rigid Rearreverse

When the rear reverse band in a 4L80E, 4L85E, or TH400 automatic transmission is worn, glazed, or burned, this rigid smooth-lining band is the direct replacement for that apply position. What sets this part apart from a friction-lined band is the smooth surface: certain apply circuits in these units call specifically for smooth lining, and installing the wrong type causes incorrect engagement feel and accelerated wear on the mating drum surface.

This is a single piece, not a kit. The box contains one rigid rear reverse band with smooth lining, nothing else. No gaskets, no seals, no steels, no frictions, no Automatic Transmission Filter are included. If your job requires a full overhaul set, you will need to source those components separately. The item ships at 2 lb, which reflects the band alone.

The 4L80E, 4L85E, and TH400 share this band position across a very long production run starting in 1965 and continuing through current production. Before placing your order, pull the identification tag or stamping from the unit and confirm the exact model and build year. These three transmission families are closely related but are not identical in every internal dimension, so confirming the unit code matters.

At REMCO, parts are. Each order is assembled by hand from individual stock, and every box goes out with a parts list so you can verify what is inside against what you ordered. REMCO has been working in automatic transmission parts since 1991, and that single-piece discipline is the same whether the order is one band or a full rebuild set.

• Covers rear reverse apply service on 4L80E, 4L85E, and TH400 units built 1965 and up, addressing worn or glazed band conditions that cause slip or harsh engagement.
• This listing is a single band only. No friction discs, steel plates, Automatic Transmission Filter, gaskets, or seals are included. Verify your complete parts list before ordering to avoid a return trip.
• Rigid construction with smooth lining suits the rear reverse circuit on these units. The rigid band holds its geometry under apply pressure, which a worn or distorted band cannot do.
• One rigid rear reverse band with smooth lining. Item weight: 2 lb. No hardware or additional components are packed in the box.
• Before ordering, confirm the transmission model code on the unit, the build year, and which band position requires service. Fits 4L80E, 4L85E, and TH400 applications.
