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

When a fluid service or teardown calls for a fresh pan gasket and Automatic Transmission Filter on a JR403E, RL4R01A, RE4R01A, or RE5R01A automatic transmission, this 2-piece set puts both items in one order without bundling parts you may not need. What makes this set specific rather than generic is the combination: a duraprene bottom pan gasket rated for this transmission family and an Automatic Transmission Filter sized for the 6-cylinder 2WD and 6-cylinder 2WD 4x4 variants of these units, covering the 1989-to-1998 production run.

The duraprene gasket compresses evenly against the pan rail, which reduces the chance of a seep after reassembly and avoids the mess of applying a bead of RTV to a surface that was designed for a formed gasket. The Automatic Transmission Filter is matched to the same family, so both pieces are ready to install together rather than sourced separately and cross-checked at the bench.

Every set is put together here by hand, piece by piece, and checked against its parts list before it ships. The box includes that same parts list, so the tech opening it on the bench can confirm both items are present before the transmission pan comes off.

This set does not include friction discs, steel plates, bands, thrust washers, or any sealing rings. If the job requires a more complete set of internal components, review your rebuild checklist and order those separately. Buying only what a job actually needs is what keeps this set useful rather than oversized.

To confirm fitment: match your unit identification code to JR403E, RL4R01A, RE4R01A, or RE5R01A; confirm the year is between 1989 and 1998; and verify the engine and drivetrain configuration is 6-cylinder 2WD or 6-cylinder 2WD 4x4. Those three checks take a minute at the counter and prevent a return once the box is open.

• This 2-piece set covers the pan gasket and Automatic Transmission Filter needed at the start of a rebuild or fluid service on JR403E, RL4R01A, RE4R01A, and RE5R01A units from 1989 to 1998.
• This set does NOT include friction discs, steel plates, bands, solenoids, or sealing rings. If your job calls for those parts, check your parts list before ordering so nothing is missing at teardown.
• The duraprene material on the pan gasket is specified for this transmission family and seats against the pan rail without requiring sealant, which matters when pan removal is part of a clean service interval.
• Exact contents: 1 bottom pan duraprene gasket (RL4R01A RE4R01A RE5R01A) and 1 Automatic Transmission Filter sized for 6-cylinder 2WD and 6-cylinder 2WD 4x4 configurations. Total weight: 1 lb.
• Before ordering, confirm your unit code matches JR403E, RL4R01A, RE4R01A, or RE5R01A, verify the model year falls in the 1989-1998 range, and check whether your application is 6-cylinder 2WD or 4x4, since that determines Automatic Transmission Filter fitment.
