6T40 [08-10] Automatic Transmission 609-007 Remanufactured

Restoring shift control to a 6T40, 6T45, or 6T50 automatic transmission starts with a functioning electro-hydraulic control module, and this remanufactured unit is built to return the assembly to its stock operating specification. What sets this part apart is that it combines hydraulic pressure regulation and electronic solenoid control in a single integrated module, so a degraded or failed unit cannot be patched around - it has to be replaced whole.

The electro-hydraulic control module sits inside the valve body and governs line pressure, clutch apply timing, and solenoid actuation simultaneously. When it fails, symptoms range from erratic or harsh shifting to complete loss of forward or reverse engagement, and scan tools often report internal control module communication faults. Replacing the module addresses the root cause rather than individual solenoids one at a time.

This listing is for the remanufactured module alone. It does not include clutch packs, friction discs, steels, Automatic Transmission Filter, gaskets, or any other mechanical components. Technicians sourcing a complete repair should confirm all additional parts before placing an order.

The part weighs approximately 5 lb and is packed individually. At REMCO, parts are assembled and verified against the item record before the box is closed, and the packing list ships inside so the receiving technician can confirm what arrived.

Before ordering, pull the transmission code directly from the unit - not from the vehicle VIN decoder - and confirm it reads 6T40, 6T45, or 6T50. This part applies to units produced from 2009 forward. Confirming the code and year before purchase avoids a return and keeps the repair on schedule.

• A failed electro-hydraulic control module causes harsh shifts, stuck gears, and no-communication faults that shut the unit down entirely.
• This listing covers the control module only. Clutch packs, steels, Automatic Transmission Filters, solenoids sold separately - verify what your repair requires before ordering.
• Remanufactured to restore stock hydraulic and electronic function: the module integrates solenoid control and pressure regulation in one serviceable assembly specific to 6T40, 6T45, and 6T50 units.
• One remanufactured electro-hydraulic control module, approximately 5 lb. Packed individually and checked against the part record before shipment.
• Before ordering, confirm the transmission code stamped on the unit matches 6T40, 6T45, or 6T50, and verify the model year of the vehicle falls within the 2009-and-up application range.
