Getting clutch pack behavior right in a TH250 or TH350 rebuild means each steel plate in the stack has to be flat, dimensionally consistent, and able to hold a fluid film between shifts. This plate carries a kolene service applied to the steel itself, not a surface coating that can flake or wear away, which keeps the microscopic texture that retains automatic transmission fluid in place through the full service life of the rebuild.
Kolene processing works by converting the outermost layer of the steel rather than depositing a material on top of it. The result is a surface that resists glazing under high-cycle use and gives the adjacent friction material something to work against consistently rather than a polished face that changes character as hours accumulate. For a technician who has gone back into a unit because the clutches started slipping earlier than expected, the condition of the steels is often part of the story.
This is a single plate. One piece, one part number, 5 lb on the scale. It does not come with friction discs, seals, an Automatic Transmission Filter, a band, or any surrounding hardware. REMCO picks and verifies each piece against the part record before it leaves the building, and a part list ships inside the box so you can confirm what arrived matches what was ordered.
Compatibility covers TH250 and TH350 transmissions from 1969 forward. Before placing the order, check the code stamped directly on the transmission case and match it to those models. Year of the vehicle and engine type are also worth confirming against your application data to avoid a mismatch on a unit that looks similar but takes a different plate geometry.
- Firm clutch engagement depends on a steel plate that keeps its shape under repeated heat cycles, and the kolene finish on this plate helps the surface hold fluid film where bare steel would wipe dry under load.
- This listing covers one steel plate only. It does not include friction discs, seals, an Automatic Transmission Filter, a band, or any other component. Confirm the rest of your parts list before ordering to avoid a return trip.
- Kolene processing changes the surface of the steel at a metallurgical level rather than adding a coating on top, so the surface texture that holds automatic transmission fluid stays present even after extended use at operating temperature.
- One kolene-treated steel plate, 5 lb shipping weight. The part number on REMCO records is, built and inspected individually before it ships.
- Before ordering, verify the transmission code stamped on your unit matches TH250 or TH350 and confirm the model year falls within the 1969-and-up range covered by this plate.
