I have a 1950 GMC i am putting in a 350 with a 700r4 do you know were you get the coumputer to make the 700r4 work in overdrive. Or do you even need a computer to make it shift into overdrive.
I have a computer that goes with a 700r4 tranny. Let me know if you can't find one, and we can make a deal.
I have a 700r4 with no computer. OVerdrive is jsut 4th gear, nothing required to make it kick in. There are 4 pins on the tranny, two can be shorted together, usign a toggle switch, to lock the tranny in over drive (4th gear) but you have to manualy have to release the short. I have seen hardware that goes in line with the speedo cable and hooks to those two terminals and autamatically locks/unlocks the OD. Try Ron Francis Wiring.
