My solution was to put in a small dash toggle switch connected to the brake switch sensor and switch off the lock out when cruising around town (back to basically a turbo 350).
Do you guys have any problem with it releasing 4th gear lock up at a reasonable throttle position? Maybe I should continue my search for a tranny swap expert.
