The Accutach Co. OSS/VSS Reverse Lockout Module allows the driver of cars equipped with electronic reverse lockout solenoids to shift into reverse any time the vehicle is stopped or moving below approximately 5-7 KM/H.  This unit is typically used with TREMEC T56, TR-6060 or T56 Magnum transmissions.

This unit works with either the 2 wire reluctor style (sometimes called analog) speed sensors or the 3 wire Hall-effect (sometimes called digital) speed sensors. It also has additional wires to make it easier to install in vintage applications where there is no existing speed signal wiring.
