Well this guy that I was talking to one night at his house was using 3 of those M-22 rockcrusher units behind big block chevys he showed me what he had, and he has owned Chevy muscle cars for years and years this individual was not some bozo I had just meet at a flee market telling me some fiction storys.

So YES I do listen to experianced credible people when they tell me that the cases on those wonderful M-22 transmissions crack, therefore there not so great to have to pay an inflated price to own them in the first place, I would believe that.

Maybe your the type of guy who babys your vehicles and you might be using them in a nice way like the factory intended, meaning you drive your muscle cars nice and smooth and slow like say an older retired person would?, under those conditions that M-22 transmission would stand up ok and not break or crack the cases.

Now it might be that the T-10 is a better stronger sports car transmission, one guy I was talking to who is also very credible who owns a auto customizing repair shop says that some of the T-10 units rebuilt sell for more then a rebuilt muncie rockcrusher does, I would look into that first.

I do know that the muncie car transmissions in general are overvalued for what they are, they should only cost used $200.00 if that, period.
