6T40 [12-17] Automatic Transmission Steel Clutch Pack Gen 2 Module

When the steel module in a 6T40, 6T45, or 6T50 automatic transmission shows wear, cracking, or distortion, clutch pack engagement becomes inconsistent and pressure distribution across the friction surfaces drops. This part addresses that directly: it is the steel module for Gen 2 production units built from 2012 onward, sold as a single piece and stocked at the REMCO facility, where it is pulled and verified individually before it ships.

The steel module in these Gen 2 units is not a soft component. It carries clamping load through the clutch pack and has to maintain its geometry under heat cycling and hydraulic pressure. A module that has warped or cracked will not hold the stack together the way the design requires, and no amount of new friction material will fully compensate for that. Replacing the module itself is the correct step when the part is the source of the problem.

This listing is for one steel module, weighing 5 lb. That is the complete scope of the item. It does not include friction discs, clutch packs, seals, an Automatic Transmission Filter, a band, or any other component. If you are assembling a rebuild and need those parts separately, they are not here.

REMCO has worked in automatic transmission parts since 1991 and assembles or packs every item at its own facility. A parts record accompanies each shipment so the technician receiving it can confirm exactly what arrived.

Before placing the order, verify that your unit carries the 6T40, 6T45, or 6T50 designation and that it is Gen 2 configuration. Build date and internal architecture differ between generations, and ordering against the wrong generation will result in a part that does not fit correctly.

• A worn or cracked steel module in Gen 2 units causes slip, heat buildup, and pressure loss; replacing it with this part addresses those failure points directly.
• This listing covers the steel module only. It does not include friction discs, seals, gaskets, Automatic Transmission Filter, or any other component. Review your parts list before ordering.
• The steel module is a load-bearing structural component in these units. Its condition directly affects clutch pack clamping force and overall shift behavior in Gen 2 applications.
• One steel module, 5 lb. Packed and verified individually at the REMCO facility against the item record before shipment.
• Before ordering, confirm your transmission code is 6T40, 6T45, or 6T50 and that the unit is Gen 2 production. Check build date and internal configuration to be certain.
