When a high-torque or performance application demands more from the clutch pack than a standard steel can deliver, the kolene-treated surface of this module provides the hardness and fluid retention that a plain steel lacks. This is a single hi-performance steel module, not a kit, and it is sold individually to match exactly the quantity your rebuild requires.
Kolene service works by converting the surface of the steel into a porous iron oxide layer. That layer holds automatic transmission fluid at the contact face between shifts, which reduces the dry-start friction that causes early glazing on the opposing friction disc. The result is a more consistent engagement feel across the service life of the clutch pack, and less thermal damage to both the steel and the friction material working against it.
This module fits the 4L60E, 4L65E, 4L70E, and TH700-R4 families, covering units from 1982 forward. Because those families share a common case and clutch pack architecture across a long production run, verify your unit identification code before ordering. Year alone is not always enough to confirm fitment when a transmission family spans multiple decades.
The module weighs 4.6 lb. It ships as a single piece. It does not include friction discs, steels for other clutch packs, seals, gaskets, Automatic Transmission Filter, band, or any additional hardware. If your rebuild calls for a complete clutch pack or a full overhaul kit, those are separate listings. Pull your parts list and match quantities before placing the order so the rebuild does not stall waiting for components that were not included here.
REMCO has worked in automatic transmissions since 1991. Each order is packed individually and verified against the order before it ships.
- A kolene-treated steel module delivers the heat resistance and surface hardness needed to hold up under high-torque and performance driving conditions, reducing glazing and heat-related slippage at the friction interface.
- This listing is for a single steel module only. It does not include friction discs, seals, gaskets, Automatic Transmission Filter, band, or any other transmission components. Review your rebuild requirements before ordering.
- Kolene surface finish produces a porous oxide layer that retains fluid at the contact face, which helps maintain consistent engagement feel and extends the service interval of the friction material working against it.
- Single hi-performance steel module, kolene-treated, 4.6 lb. Fits 4L60E, 4L65E, 4L70E, and TH700-R4 automatic transmission units built from 1982 onward.
- Before ordering, confirm your unit identification code (4L60E, 4L65E, 4L70E, or TH700-R4), the model year of the vehicle, and whether your application calls specifically for a kolene-treated module rather than a standard steel.
