Ok, I am installing my 700R4 on my 425 dual quad engine. i have all the linkages figured out and the driveshaft out getting shortened. I was about to install the vacuum switch for the torque lock up but I am beginning to think there is more to it than that. What do I need to do to lock up my torque after 4th gear engagement? Is it just a matter of hooking up a vacuum switch to the plug on the left rear of the trans or do I need another kit that goes inside the trans? Thanks for any help.
