Re: How to change your 5 speed to an automatic

Just found this diagram, and I can understand it .

What do you think?

Run a 12v (+) from a momentary switch to the on pulse, and the 12v (+) from the brake light switch to the off pulse to run the TC lock up. Yes?. And maybe another of the same for OD operation. I don't think I will need to use the electronic pressure control wire because the Transgo kit adds a vacuum modulator valve to control the pressure put I still may need a pressure switch to keep from locking the TC at low pressure/low speed. Maybe the pressure switch would be wire to the Fused 12v (+) in the diagram?

EDIT: did more reading. The pressure switch kicks the lock up off at high loads/pressure, and kicks OD off when downshifting so you don't forget to turn it off then upshift from 2nd to 4th. So I think it would need to be tied in on the same wire as the brake, and into the OD relay pack as well.
