When the electronic brain of the transmission fails, no amount of mechanical work will correct shift feel, and replacing the Transmission Control Module is the direct path to restoring normal operation. This TCM is listed as a single unit under part number 609-035, built specifically for 6F50 and 6F55 automatic transmission applications, with no bundled extras that could complicate a straightforward electrical repair.
The 6F50 and 6F55 are six-speed automatic transmission units that rely on precise electronic signals from the control module to manage line pressure, shift timing and solenoid activation. When that module develops internal faults, symptoms can range from delayed engagement and erratic shifting to complete failsafe lockout. Swapping in a correct, matched TCM addresses the root cause rather than chasing secondary symptoms through the valve body or solenoid pack.
This part ships at 5 lb and contains one module, nothing more. There are no solenoids, no sensors, no harnesses and no mechanical components in this package. If your repair also requires those items, they need to be sourced separately. Technicians should confirm the transmission code on the unit reads 6F50 or 6F55 and verify that part number 609-035 corresponds to their specific application before placing the order. A wrong-unit TCM will not communicate correctly with the vehicle electronics and will not resolve the fault. REMCO has specialized in automatic transmission components since 1991, and each item that leaves the facility is checked against its part record before it is packed.
- Restoring correct electronic shift control stops erratic gear changes, harsh shifts and communication faults that leave the transmission unresponsive or stuck in failsafe mode.
- This listing covers the Transmission Control Module only. It does not include solenoids, wiring harnesses, sensors or any mechanical components. Verify all other parts before ordering.
- A single dedicated TCM for 6F50 and 6F55 units keeps the repair focused: one part number, one function, no bundled items you may already have on the bench.
- Contains one Transmission Control Module, part 609-035, weighing 5 lb. No additional pieces are included in this shipment.
- Before ordering, confirm the transmission code stamped on the unit matches 6F50 or 6F55, and cross-reference the part number 609-035 against your unit to avoid a misapplication.
