RE4R01A [89-98] Automatic Transmission [87-04] Frictions

For RL4R01A automatic transmissions. When a JR403E automatic transmission rebuild stalls because friction discs are scattered across multiple suppliers, this kit puts all 26 of them in one box, sorted by clutch pack and ready to count. That is the direct problem it solves: one order, one delivery, no hunting for individual part numbers across six different clutch sets.

What makes this article specific is the combination of disc geometries it covers. The low reverse clutch gets 7 frictions at .076 inch thickness with 30 teeth. The forward clutch gets 7 discs at .063 inch and 36 teeth, referenced under R4AXEL fitment for 1995 and up. The high clutch is served by 5 pieces at .063 inch with 30 wide teeth, covering RL4F02A and RE4F02A units from 1987 up. The overrun clutch receives 3 discs at .079 inch and 18 teeth, and the reverse clutches split into two sets: 2 frictions at .079 inch with 34 teeth and 2 more at .078 inch with 30 teeth, the second set under R4AXEL from 1992 up.

REMCO has been working in automatic transmission parts since 1991. Every kit is assembled here by hand, part by part, and checked against the packing list before the box closes. That list ships inside the box so the technician at the bench can verify count before a single disc goes into the unit.

This is a Friction Kit, which means it covers frictions only. There are no steel plates, no Automatic Transmission Filter, no gaskets, no seals, and no band in this box. If your rebuild requires those components, they need to be sourced separately. Check your rebuild checklist against the contents above before placing the order. Application covers the JR403E, years 1989 through 1998. Verify the code stamped on the unit and the model year before ordering.

• RL4R01A automatic transmission: consolidating all six clutch-pack frictions into one order cuts sourcing time and reduces the risk of missing a critical disc during rebuild.
• This kit contains friction discs ONLY. No steel plates, no Automatic Transmission Filter, no seals, no gaskets, no band. Confirm your full parts list before ordering to avoid a return.
• Six distinct clutch packs covered in a single box: low reverse, forward, high, overrun, and two reverse clutch sets, each counted and verified against the kit sheet packed inside.
• 26 friction discs total: 7 low reverse (.076 in, 30T), 7 forward (.063 in, 36T), 5 high (.063 in, 30T wide), 3 overrun (.079 in, 18T), 2 reverse A (.079 in, 34T), 2 reverse B (.078 in, 30T). Kit weighs 3 lb.
• Before ordering, confirm the transmission code on the unit matches JR403E and that the model year falls within the 89-98 range covered by this kit.
