4T80E [93-UP] Automatic Transmission Rear Band Rigid

A failed or glazed low reverse band in a 4T80E automatic transmission shows up fast: soft reverse engagement, slipping in manual low, or a unit that hunts between ranges and never quite locks in. This is the rigid rear double-wrap relined replacement band for that position, built to restore firm, repeatable apply without the guesswork of sourcing a relined piece separately.

The double-wrap rear configuration means the band contacts the drum across a wider arc than a single-wrap design, spreading apply force more evenly and reducing the chance of localized wear on the drum surface. The rigid construction keeps the band geometry consistent from the first apply cycle onward, which matters when the servo is calibrated to a known band stiffness. A flexible band that distorts under load changes the effective apply point and can cause inconsistent shift feel even after a full rebuild.

This band covers 4T80E units from 1993 forward. Before placing the order, pull the transmission ID and confirm the code is 4T80E. Year of manufacture and the specific variant of the unit should both be verified against the unit itself, not assumed from the vehicle it came out of.

This listing is for the band as a single piece. It does not include clutch friction discs, steel plates, an Automatic Transmission Filter, gaskets, seals, or any other rebuild components. If you are doing a complete overhaul, those parts need to be sourced separately. At 1 lb, the band ships light, but double-check your full parts list before the job is on the lift.

REMCO has been working in automatic transmission parts since 1991. Each piece is checked before it goes out the door.

• Replacing a worn low reverse band stops slippage in reverse and low range before it damages drums or other hard parts inside the unit.
• This listing is for the band only. Clutch packs, steels, Automatic Transmission Filter, gaskets, and seals are not included. Verify your full rebuild needs before ordering.
• The rigid double-wrap rear design holds its shape under repeated apply cycles, maintaining consistent contact with the drum surface compared to a flexible band that can distort over time.
• One relined rigid low reverse rear double wrap band, 1 lb. The part is inspected before it leaves and ships with a piece-count reference so you know exactly what arrived.
• Before ordering, confirm the transmission code on the unit itself is 4T80E and that the application year falls within the 93-UP range. Do not rely on vehicle model alone.
