RE4R01A [87-UP] Automatic Transmission Steel Clutch Pack ( j-30) Module

When the steel module inside a JR403E or RE4R01A wears beyond its usable surface, the friction discs have nothing consistent to grip against, and the clutch pack loses the clamping force the automatic transmission needs to hold each gear under load. This listing covers the steel module for that unit, a single piece weighing 4.06 lb, catalogued under model RE4R01A and applying to JR403E transmissions built from 1989 through 1998.

This is not a rebuild kit. There are no friction discs, no seals, no gaskets, no Automatic Transmission Filter, and no additional hardware included. If your repair calls for a complete overhaul, you will need to source those components separately. The steel module ships alone, and that is intentional: technicians who already have the rest of their parts on the bench should not have to pay for duplicates they do not need.

At 4.06 lb, the piece has the mass and surface area the clutch pack depends on. Dimensional fit is everything with a steel module; a piece that is off by even a small margin will drag, overheat, or fail to release cleanly. This part is listed specifically for the JR403E and RE4R01A, so the match to those units is the starting point of any decision to order it.

Before placing the order, locate the transmission code on your unit and confirm it reads JR403E or RE4R01A. Also verify the build year sits inside the 1989-1998 window. If either detail does not match, this is not the correct piece for your application. REMCO has been working with automatic transmission parts since 1991 and every shipment goes out with a parts list so you can confirm on arrival that what was ordered is what arrived.

• A worn or glazed steel module causes slipping and heat buildup inside the unit; replacing it with a correctly sized piece stops that wear cycle before it damages other components.
• This listing is for the steel module only. It does not include friction discs, seals, gaskets, Automatic Transmission Filter, or any other rebuild components. Review your parts list before ordering to avoid a return trip.
• The steel module for the JR403E and RE4R01A is a single structural piece, not a kit. At 4.06 lb it carries the load and heat that softer friction materials cannot handle on their own, making fit and dimension the deciding factors here.
• Contents: one (1) steel module, 4.06 lb. No additional pieces are included in this shipment. What you see listed is exactly what ships.
• Before ordering, confirm the transmission code stamped on your unit matches JR403E or RE4R01A and that the build year falls within the 1989-1998 range. A mismatch in code or year means this piece will not apply.
