6L80E 6L90E [06-UP] Automatic Transmission Solenoid Remanufactured TCM OE

A failed transmission control module in a 6L80 or 6L90 unit can produce symptoms that range from harsh or erratic shifts to a transmission that refuses to engage a gear at all, and replacing it with a remanufactured unit built to stock specification is the direct path to restoring normal automatic transmission operation. What sets this module apart from a generic replacement is the breadth of OE part numbers it covers: 24256939, 24257213, 24259835, 24261870, 24264141, 24265259, 24267576, 24270598, 24275873, and 24276637, giving it broad application across 6L80E and 6L90E assemblies from 2011 forward.

This listing covers a single control module. It does not include any solenoids, solenoid harness, valve body components, Automatic Transmission Filter, or internal mechanical parts. If your diagnosis points to more than the module, those components need to be sourced separately before the transmission goes back together.

The unit weighs 4.15 lb and applies to transmissions identified as 6L80E, 6L90E, 6L80, or 6L90, model year 2011 and up. Because multiple OE part numbers exist within this family and not every assembly uses the same module, the correct step before ordering is to locate the part number on your existing module and confirm it appears in the list above. Ordering by transmission model code alone is not sufficient and can result in a return. REMCO has specialized in automatic transmission components since 1991, and this module is handled and verified individually before it ships.

• Restores accurate shift control and avoids erratic behavior caused by a failed transmission control module in 6L80 and 6L90 units built from 2011 forward.
• This listing is for the control module only. It does not include solenoids, valve body, Automatic Transmission Filter, or any other internal transmission component. Verify what else your repair requires before ordering.
• This is a remanufactured unit built to stock specification, cross-referencing OE part numbers 24256939, 24257213, 24259835, 24261870, 24264141, 24265259, 24267576, 24270598, 24275873, and 24276637.
• Single unit. Weight: 4.15 lb. Applies to 6L80E and 6L90E transmissions, including base designations 6L80 and 6L90, model year 2011 and up.
• Before ordering, confirm the exact transmission code stamped on your unit and match it against the OE part numbers listed. Not all 6L80 and 6L90 assemblies share the same module part number.
