I have an 84 700r4 and I removed the ecm so I lost the lock up. I tried to wire up a toggle switch for it but accidently switched pin A and B. So pin A was grounded and is should have 12V going to it. B had 12V through it and its supposed to be grounded. C has been grounded the whole time. Now that I switched A and B around to the way it should be it still doesn't want to lock up. Did I fry something in the trans when I had the A and B switched around?
