So I have a mildly modded 88gt. My T5 is raking gears and popping out of second. The car is to be a fun car with a trip to the track now and then. I am considering buying a new T5Z from CJ Pony for $1295. I would sooner have mine rebuilt/upgraded or buy a rebuilt one that is cheaper. I am in south central Pa. Does anyone know a good rebuilder or a place that sells a good upgraded unit online that will be trustworthy? I only want to do this once. Thanks..my email is powershift@comcast.net if you wanna contact me direct.
