i know there is the BD torquelock, but that is way too complicated and expensive. on a dodge all you need is a wire and a switch and you can manually lock it. im startin to look through some haynes manuals cause there has to be an easier and cheaper way. if anybody has any insight on this feel free to correct me.

At last speculation I was looking at adding a verible resistor to the force motor circuit.

this is one i found for a 700R4. pretty darn simple.

Several have tried with very limited success; but Pulse Width Modulation lockup control on a OBDII 4L80, make aftermarket lock up kits not worth the effort.
