FIOD 4R70 4R75 [90-UP] Automatic Transmission Front Band Flex

For FIOD automatic transmissions. A worn or glazed overdrive band is one of the quieter causes of slipping in 4R70W, 4R75W, and 4R70 automatic transmission units, and replacing it with a flex band is a straightforward step that directly addresses that failure point. What sets this specific part apart is the 2-wide contact surface, which matches the overdrive drum geometry found in these units and must be correct for the band to seat and apply pressure the way it was designed to.

This is a single flex band, not a kit. It covers 4R70W, 4R75W, and 4R70 automatic transmission builds from 1990 and up, cataloged under the FIOD line. bonding on the friction surface holds up better under the heat cycles that overdrive engagement generates compared to standard materials, which matters most in units that see frequent highway use or towing conditions.

Before placing the order, pull the pan and confirm two things: the unit identification code stamped on the case or tag, and the actual width of the overdrive drum. The 2-wide designation is not interchangeable with a 1-wide drum. Using the wrong band width results in improper apply and the same symptom you started with.

This band ships as a single piece. It does not come with seals, gaskets, clutch discs, steels, Automatic Transmission Filter, solenoids, or any other rebuild components. At REMCO, parts have been pulled and checked against their item record since 1991, so what arrives matches what was ordered. Weight is approximately 1 lb.

• FIOD automatic transmission: construction on this 2-wide flex band handles overdrive drum engagement with less heat buildup than standard bonded bands, reducing slippage risk during high-load shifts.
• This listing is for a single band only. It does not include any solenoids, seals, gaskets, clutch packs, steels, Automatic Transmission Filter, or rebuild kit. Verify what else your repair needs before ordering.
• The 2-wide contact surface on this overdrive flex band matches the drum width found in 4R70W, 4R75W, and 4R70 units, making it a direct fit without trimming or modification.
• One overdrive flex band, 2-wide. Approximate shipping weight: 1 lb. Packed and verified against its part record before leaving the warehouse.
• Before ordering, confirm your unit code matches 4R70W, 4R75W, or 4R70 and that the overdrive drum in your unit takes the 2-wide band. An AODE with a different drum width requires a different part.
