Ok, Luckily my aftermarket warranty (good thing they never seen my car) payed for my rebuilt tranny...I was wondering by driving hard like heavy acceleration flooring it does this harm my tranny? I want to keep this one in good condition the guy told me they will not warranty the tranny again if it comes back looking the way it did? Its also shifting farely ruff right now

 

yes, that will cause stress on the tranny, another big stresser will be punching it while in 4th and having the tranny down shifting to 2nd. It can handle them, it just causes stress.
