When the job calls for a full friction disc refresh on a JR403E unit, this Friction Kit from REMCO puts all six clutch set frictions in a single box, counted and verified before it ships. What sets this kit apart is the specificity of its contents: six distinct part numbers covering low reverse, forward, high clutch, overrun, and two separate reverse clutch applications, each selected for the correct tooth count and disc thickness required by this automatic transmission family.
REMCO has been working in automatic transmission parts since 1991, and every kit is assembled here by hand, piece by piece, against a parts list. That list ships inside the box so the rebuilder can check off each disc before the transmission goes on the bench.
The box holds 26 friction discs in total. The low reverse clutch set contributes 7 discs at .076 inch thickness with 30 teeth. The forward clutch set adds another 7 discs, thinner at .063 inch, with 36 teeth. The high clutch set brings 5 discs also at .063 inch but with 30 wide teeth. The overrun clutch set accounts for 3 discs at .079 inch with 18 teeth. Two reverse clutch discs at .079 inch with 34 teeth round out one set, and a final 2 discs at .078 inch with 30 teeth complete the other reverse clutch group. Total kit weight is 3 lb.
This kit does not include steel plates, seals, gaskets, Automatic Transmission Filter, or bands. It is a friction-only kit. Builders who also need those components should source them separately before starting the job. Confirm that the unit on the bench carries the JR403E code and falls within the 1989 to 1998 production range before placing the order. Catalog reference for this application is RL4R01A.
- Covers the full friction disc replacement for JR403E automatic transmission rebuilds spanning the 1989 to 1998 application range, targeting clutch slippage and worn disc failures across all six clutch packs in the unit.
- THIS KIT CONTAINS FRICTION DISCS ONLY. No steel plates, no Automatic Transmission Filter, no seals, no gaskets, no bands are included. Verify your parts list before ordering to avoid a return trip.
- Six distinct clutch sets in one box: low reverse, forward, high, overrun, and two reverse clutch friction sets, each with its own tooth count and thickness spec to match the stock design of the JR403E.
- 26 friction discs total across 6 part numbers: 7 low reverse (.076 / 30T), 7 forward (.063 / 36T), 5 high clutch (.063 / 30T wide), 3 overrun (.079 / 18T), 2 reverse (.079 / 34T), 2 reverse (.078 / 30T). Kit weighs 3 lb.
- Before ordering, confirm the transmission code on the unit matches JR403E and that the model year falls within the 1989-1998 range covered by this kit. Cross-reference catalog model RL4R01A.
