i have an 87 700r4 in my 1990 van, and i'm looking for an explaination of what goes on electrically with the lockout tcc. There's 3 wires coming into the trans... i know 1 is 12v+, one is ground, and the other one is?
Is it feedback to the computer telling it that it's locked out, or is it feedback to the computer telling it that it's in OD or 4th? If one was to bypass all the sensors in the trans, how would one wire it?
Thanks,
Dan

 

I pretty much asked the same question like two days ago, it all depends on how you want it really, you can have it lock up in OD only or you can lock it up however you want, with a toggle switch, and some 12volt power. Search here or Google it
