hey Scratch, yeah mine does have the switch at the back above the pan rail & I just got through talking to the transmission shop, they said just to leave it unhooked that only I would have not lockup which is fine that it will just shift like a regular 3 speed & they claimed that there wouldn't hurt anything & he's built a lot of Chrysler transmissions for 40 years. He's built most of my trans when they've needed to be rebuilt, but thanks for the reply & help
