When the overdrive drum band in a 4R70W, 4R75W, 4R70, or 4R75 automatic transmission wears or breaks, the unit loses the ability to hold overdrive, and no amount of electrical diag nosis will fix a mechanical failure at that point. This listing is for a single flex band designed specifically for the overdrive drum position in those four transmission families, covering units built from 1992 through current production.The flex construction allows the band to conform evenly around the drum as it applies, spreading the clamping load across a wider contact area rather than concentrating stress at fixed points the way a rigid band does. That characteristic matters in a high-cycle position like the overdrive drum, where apply and release events happen constantly during normal driving.This is a single-piece item, not a kit. It does not include friction clutch packs, steel reaction plates, a filter, a rebuild gasket set, solenoids, or any other component. If your repair calls for additional parts, those need to be sourced separately. Review your disassembly notes and the unit condition before placing the order so you receive exactly what your job requires and nothing is missing when the transmission goes back together.At REMCO, parts are pulled and verified individually before they leave the facility. A piece record accompanies each item so the contents match what was ordered. REMCO has worked in automatic transmission parts since 1991, and single components like this band are handled with the same attention applied to full rebuild kits.Confirm the transmission model code on your unit, the build year, and the exact band position before ordering. The 4R70W, 4R75W, 4R70, and 4R75 share a common architecture but production changes over a long model run can affect fitment. When in doubt, cross your unit tag against the application before purchasing. Restores overdrive drum holding capacity in 4R70W, 4R75W, 4R70, and 4R75 units built from 1992 onward, addressing slip and loss of overdrive engagement. This listing covers the flex band only. It does not include friction discs, steel plates, filter, solenoids, or any other components. Verify what your repair requires before ordering. The flex band design allows even load distribution around the overdrive drum surface, reducing concentrated wear compared to a rigid band in the same position. One flex OD drum band. Item weight: 1 lb. Pulled individually at the REMCO facility and checked against the item record before shipping. Before ordering, confirm the transmission code stamped on the unit, the build year, and the specific band position you are replacing to make sure this part matches your application. Show more
