I've got a trans am I am looking in to switching out transmissions again from my liberty pro-shifted and I'm wondering do I want to get a built t56 or go with a mn12 for my car. I don't drag race I do a lot of mountain driving. The car has seen the dragon alot since I only live about 35 minutes from the dragon general store. Just looking for little insight.

 

the GTO trans is a lot like the Vette trans, it has triple cone 1-2 and 3-4-5-6 have double cone syncros (faster down shifting), and upgrade internal parts.
