    I have an 86 pickup with a T400 and 208 case. I want to swap in a 700R4 from an 89 with the 241 case. Can I just use a stahl converter to get away from the lock-up torque converter? I know about the TV cable. I have a 700R4 in my Jeep YJ but I bought it from JET and it has no electrical conections so I know it is possible.

    I would like to take advantage of the lower 1st gear and also the overdive now that I am running 456 gears

    You can make a 700R4 into a non lock-up but there are some things inside that need to be changed.
