On a tranny rebuild, is it always necessary to install a new or rebuilt T.C.? Is there any way of finding out if the old one is reusable? My tranny gave out because I got the lines crossed when installing a remote oil filter so my Overdrive unit gave out. The main case was luckily unaffected. I honestly don't think my T.C. was affected. Could any tranny shop test it and confirm this? Roughly how much would that cost? I'm on a tight budget, but at the same time, if I need to buy it for my tranny, then so be it. Thanks again MonteC, I hope I'm not getting TOO annoying.
