My 700R4 only locks up in 4th gear. I have a toggle switch so I can unlock if I need to. I think I ran a wire from a key on post from the fuse box to a toggle switch and from the toggle switch to the Transmission.
Thank you guys. I appreciate your help. I think I'll do the toggle switch first. I may try the cruise control later. My thinking on the cruise control, that it would disconnect without causing damage due to forgetting to shut the toggle off.
