Having six gears is a joy. But stacking all those gears in a transmission case means sometimes there are compromises. Fifth gear and Reverse on T-56 and Magnum transmissions are really close. It’s important to use a safety lockout to avoid accidentally shifting into reverse on the freeway!
Historically, this lockout is achieved by intercepting the brake light wire, telling the solenoid you are stepping on the brake and energizing the lockout to open the gate. The problem is that sometimes you step on your brake at speed and could easily put your car into reverse on the road.
The new American Powertrain module eliminates that problem by using the VSS speed sensor in the transmission to tell the solenoid you are at zero mph and can therefore safely put your car into reverse. It easily wires to Magnum or T56 6-Speed to unlock reverse when the car is not moving. The most elegant and simple way to hook up your reverse lockout solenoid includes module, solenoid pigtail and full instructions. Available now online for $129.00.
