RL4F03A RE4F03A [91-25] Automatic Transmission Filter ON AND PAN Gasket

Getting the fluid circuit right on an RL4F03A or RE4F03A rebuild starts with two parts that are easy to overlook: the pan gasket and the Automatic Transmission Filter. This set addresses both in a single order, with a duraprene bottom pan gasket and an Automatic Transmission Filter unit matched to these transmissions from 1990 and up.

The duraprene pan gasket is cut for the RL4F03A and RE4F03A pan rail, which means it aligns to the bolt holes without any trimming and compresses evenly when the pan is torqued down. A gasket that does not match the rail geometry will weep fluid at the seam regardless of how carefully it is installed, so using a part specific to this automatic transmission matters more than it might seem on the bench.

The Automatic Transmission Filter, part number RLRE4F03AVB, covers the same unit family from 1990 forward. A clogged or degraded Automatic Transmission Filter restricts flow to the valve body and clutch circuits, which shows up as sluggish shifts or pressure complaints. Replacing it at the same time as the gasket is standard procedure and avoids reopening the pan later.

What this set does not include: friction discs, steel plates, bands, or any sealing rings. If your rebuild requires those components, they need to be sourced separately before the transmission goes back together. Check your parts list against what is in this kit before ordering.

Each kit is assembled at REMCO by hand, piece by piece, then verified against its own parts list before the box is closed. A printed list of contents ships inside the box. REMCO has worked in automatic transmissions since 1991. Total weight is 1 lb.

• A clean Automatic Transmission Filter and a sealed pan are the starting point for any automatic transmission service that holds fluid pressure and avoids leaks after the job is done.
• This set does NOT include friction discs, steel plates, or bands. Review your full parts list before ordering to make sure those items are sourced separately.
• The pan gasket in this set is duraprene material, chosen for the RL4F03A and RE4F03A bolt pattern and sealing surface so it seats without trimming or modification.
• Exact contents: 1 duraprene bottom pan gasket for RL4F03A and RE4F03A, 1 Automatic Transmission Filter RLRE4F03AVB rated from 90-UP. Total kit weight is 1 lb.
• Before ordering, confirm the transmission code stamped on your unit matches RL4F03A or RE4F03A and verify the model year falls within the 1991-UP application range.
