I jusy bought a blown 95 z28 with a art carr extreme th-700r4 transmission. My question is is there a difference in the compition models vs the extreme models? From what i been reading the compition model goes for around 2k, I have a reciept right here saying the guy spent $4,000 on this tranny.Either way It didnt cost me anything and a scored the car for a bit more than what he paid for the transmission. This is my first camaro and im just trying to build up some knowledge on the parts that are in the car.
