I want to lock my TC in 3rd at WOT for dyno purposes. How do I go about it? BTW I have a 700-r4.

 

Theyre should be a wiring harness coming from your tranny, use a manual to figure out which wire controls lockup, (in my 94 it was the brown one, but you shouldnt have many wires to pick from being a 700r4) run it inside the car to a toggle switch (dosent have to be anything special, its just a ground circuit) run into the switch, with the wire from the tranny and than out the other post to a good ground, oh, and by the way, it needs to be a 2 position, two blade switch, hope this helps, prorac1
