Re: TCC Lockup Kit 700R4 (Which is best???)
an external only kit wont work if the stuff in the pan isnt there. Unless you know for a fact that everything is right. You can read the TCC lockup thread and do the recommended check to see if you have the N.O. switch or the N.C. switch. You can do that without dropping the pan I believe. Then you can wire it from there.
Trans Im messing with right now didnt even have a 4th gear switch installed in the valve body. So if you want it done right, drop the pan. Its not that much work and you could probably go for a filter change anyways.
