4L80E [64-UP] Automatic Transmission Front Band Flex () (1.25 Wide)

When the front band in a 4L80E or 4L85E automatic transmission wears down, the unit loses the ability to hold cleanly during apply events, and slipping or delayed engagement follows. This single front flex band uses a lining and measures 1.25 inches wide, which are the two specs that matter most when sourcing a direct replacement for these units.

The lining resists the heat and repeated flex cycles that are normal in the front servo circuit of these automatic transmission models. A standard lining can harden over time and lose surface friction before the band itself fails structurally. The flex design allows the band to conform evenly around the drum during apply without concentrating stress at a single point.

This is a single-piece listing. No servo components, pins, pistons, Automatic Transmission Filter, or additional hardware are included. If your job calls for those parts, they need to be sourced separately. Check your parts list before placing the order.

This band is built for 4L80E and 4L85E units covering the [64-UP] production range. Before purchasing, confirm the transmission identification code on the unit itself and that the application year falls within that range. The item ships at 1 lb. At REMCO, parts like this are picked and checked individually against the item record before packing, so what arrives matches what is listed.

• Restoring slip or flare on the front servo circuit starts with a band that holds under load without glazing or cracking over time.
• This listing covers the band only. It does not include servos, pistons, pins, Automatic Transmission Filters, or any other components. Verify your full parts list before ordering.
• lined flex construction handles the flex and heat cycles of the front circuit in these units, where a standard band tends to harden and lose grip faster.
• One front flex band, lining, 1.25 inches wide, rated for 4L80E and 4L85E applications. Item weight: 1 lb.
• Before ordering, confirm the transmission code on your unit is 4L80E or 4L85E and that your build year falls within the [64-UP] range. One band per listing.
