TH325 -4L [79-UP] Automatic Transmission Pan Gasket on Fliter and Filter

When the pan comes off and you need exactly two parts to put it back together clean, this set delivers them without extras that drive up cost or clutter the bench. It pairs one cork bottom pan gasket sized for TH325 and 4L units with one 81-style Automatic Transmission Filter for TH325 applications, both pulled from the same box and both verified against the parts list before the box is sealed.

The cork gasket is the detail that sets this combination apart from an Automatic Transmission Filter-only purchase. Cork compresses gradually and consistently along the pan rail, which matters on older housings where the surface is not perfectly flat. A gasket that gives a little under the bolt pattern is less likely to develop a seeping leak after the first fluid fill than a rigid alternative on the same surface.

The Automatic Transmission Filter is the 81-style unit specified for TH325 units built from 1979 onward. If the automatic transmission on the bench falls inside that range and the code matches, this is the Automatic Transmission Filter that fits without modification.

Each of these two pieces is counted and matched to the packing list at the time the box is assembled here at REMCO. The list ships inside the box, so you can cross-check on the spot before you even set the parts on the bench. REMCO has been working in automatic transmission parts since 1991, and that process of assembling each order by hand from individual components is how the count stays accurate.

This set does not include friction discs, steels, bands, or any additional sealing components. It is a targeted 2-piece service set for the pan and Automatic Transmission Filter only. Confirm the transmission code reads TH325 or 4L and that the build year is 1979 or later before placing the order.

• Finish the job without a second order: this 2-piece set covers both the bottom pan seal and the Automatic Transmission Filter in one box, keeping the teardown moving.
• This set does NOT include friction discs, steel plates, bands, seals, or any other rebuild components. Check your parts list before ordering to confirm these are the only two items you need.
• The pan gasket is cork, which compresses evenly against the pan rail and reduces the chance of weeping leaks that show up after the first fluid fill.
• Contents: 1 cork bottom pan gasket for TH325 and 4L units, and 1 Automatic Transmission Filter (81-style) for TH325 applications from 1979 up. Total weight: 1 lb.
• Before ordering, confirm the transmission code on the unit matches TH325 or 4L and that the application falls within the 1979-and-up range. Do not rely on the vehicle year alone.
