RE4F04A RE4F04B [92-UP] Automatic Transmission Front Band Flex

When the servo band in an RE4F04A automatic transmission wears or burns through, replacing that single component is often the most direct path to restoring proper gear hold and forward engagement. This listing covers one individual band for the RE4F04A unit, sold as a standalone piece for technicians who have already diagnosed the fault and need exactly that part without paying for components they do not require.

The RE4F04A automatic transmission uses this band as part of its servo apply system. A failed or glazed band causes slipping, delayed shifts, or complete loss of a range depending on how far the wear has progressed. Swapping only the band lets a technician address a confirmed diagnosis without disturbing the rest of the assembly if the remaining internals are still serviceable.

This is not a rebuild kit. There are no friction discs, no steels, no Automatic Transmission Filter, no gaskets, and no seals in this order. If your repair requires additional components, those must be sourced separately. Review your parts checklist against what this listing provides before placing the order.

REMCO has been working in automatic transmission parts since 1991. Each order is packed individually and checked against its parts list before it ships, so what you receive matches what is described here. The part ships at 0.65 lb.

Before ordering, pull the transmission identification tag and confirm the code reads RE4F04A. Also verify the model year and engine size of the vehicle you are working on, since similar units can share a body style but differ internally. Ordering the wrong band adds time to a job that is already off the road.
