Here is the latest product from GRC Performance. It is the T56 6 speed reverse lockout actuator. This unit will lock out reverse above 3 mph and unlock reverse below 3 mph. It does this by picking up the signals from the VSS sensor through the yellow wire, red is switched power, and black is ground. Currently, the only way to put the transmission in reverse is to force it in with 2 hands which overpowers the actuator mounted on the side of the transmission. The unit is contained in a weatherproof housing for durability, and comes with a factory style connector for the trans mounted actuator and additional connectors for the other wires. This unit will eliminate the need for manually operated toggle switches or other devices that can allow the driver to accidentally put the transmission into reverse will driving. Units come with a 1 year warranty.
