6T40 [14-UP] Automatic Transmission Remanufactured Control Module TCM

When the Transmission Control Module fails on a 6T40, 6T45, or 6T50 automatic transmission, the unit loses its ability to interpret sensor data, command solenoids, and execute shift logic, and replacing the TCM with a remanufactured unit is the direct path back to normal operation. This is a single remanufactured TCM, SKU, built for 2014 applications of the 6T40, 6T45, and 6T50 family, and it is not a kit, not a set of parts, and not bundled with anything else.

Remanufacturing means the module has been processed and verified, not simply cleaned and resold as used. REMCO has specialized in automatic transmission components since 1991, and every unit that ships goes through a check before it is packed. The box contains the module and a part listing confirming what is inside, nothing more.

This listing covers a single-year application: 2014. If your unit falls outside that range, this module is not the correct one. The 6T40, 6T45, and 6T50 share a platform but can carry different calibrations depending on the specific vehicle configuration, so the technician should confirm the exact transmission code on the unit before ordering. The module does not include a wiring harness, solenoids, valve body, or any mechanical component. If additional parts are needed for a full repair, those must be sourced separately.

At 3 lb, this is a compact electronic component. Handle it as you would any remanufactured control module: protect it from static discharge during installation and confirm the root cause of failure before fitting a replacement unit, since an underlying electrical fault can affect a new module the same way it affected the stock.

• Restores electronic control to the transmission by replacing a failed or corrupted module, preventing shift errors and communication faults that leave the unit unable to function correctly.
• This listing is a single remanufactured TCM only. It does not include solenoids, valve body, wiring harness, or any mechanical components. Verify your full repair needs before ordering.
• The module is remanufactured, not new-old-stock and not a raw used unit pulled without inspection. REMCO has worked in automatic transmissions since 1991 and verifies each unit before it leaves.
• Single remanufactured Transmission Control Module, part number, compatible with 6T40, 6T45, and 6T50 units. Article weight: 3 lb.
• Before ordering, confirm the exact transmission code stamped on the unit, the model year (2014 only for this application), and that the TCM is the confirmed failed component in your diagnosis.
