(888) 312-8812 Login SignupThe Allison Transmission Internal Wiring Harness Kit is a replacement wiring kit for the control valve inside an automatic transmission, where it links the valve solenoids with the control module. Fitting the 1000, 2000, 3000 and 4000 Series, the Allison Transmission 29549576 lets a shop that services several transmission families stock a single harness kit. Wiring inside the transmission works in hot fluid beside the valve body, which makes a sound harness important for every solenoid connection. Replacing the harness as a complete kit avoids splicing individual wires during a valve body repair.
