When the front bushing in the reverse drum wears out, the drum loses its centered support and shaft movement increases with every shift, accelerating damage to surrounding components inside the automatic transmission. This single bushing, sized at 2.11" outer diameter, is the direct replacement for that front reverse drum position across the 4L60E, 4L65E, 4L70E, and TH700 transmission family, covering applications from 1982 forward.
The reverse drum front bushing sits at a load point that cycles on every reverse engagement and during the 1-2 shift sequence. A worn bushing at this location shows up as noise, delayed engagement, or visible drum wobble when the unit is disassembled. Replacing it before reassembly is a straightforward step that restores the end play the drum was designed to run at.
This listing covers one bushing. There are no clutch plates, steels, seals, Automatic Transmission Filters, or rebuild components included. If you are sourcing parts for a full overhaul, check your parts list separately and confirm this is the specific piece you still need before ordering.
Since 1991, REMCO has been working exclusively in automatic transmissions. Each order is hand-packed at our facility and ships with a printed parts list inside the box so you can verify the piece on arrival. The item ships at 1 lb.
Before placing your order, confirm that your unit carries one of these codes: 4L60E, 4L65E, 4L70E, or TH700. Also confirm the model year falls within the 1982 to present application range and that the front position of the reverse drum is the location requiring replacement, not the rear bushing or another drum entirely.
