You know the torque convertor lockup boxes. (B&M makes one) They are supposed to control the lockup on a automatic tranny from 30-90 mph. HOw hard would it be to lower the Mph of where it locks up the convertor to 5 mph? The guys putting t56's into their cars could use a convertor lockup to activate the solenoid that allows them to shift into reverse. I bet it wouldent be hard to change the mph where it locks up the convertor. It probably has an reostat, It might be as easy as adding a resistor.

It would depend on whether the B&M circuit boxes were encapsulated, or not. It would probably be easier to build a frequency to voltage converter & drive it from the VSS to control the reverse lockout on a T56.
