I had my tranny internals cryoed. havent had a chance to run with the new tranny yet, but Ill be sure to let you know how they hold up!
theres another 383 fiero that has had their tranny cryoed, I believe the blew up 8 or 9 trannys before they decided to try cryotreating one, so far the same one is still holding up after a few years of the same kind of abuse.
