My trans mystifies me. It wont slip at all and im on level 5 on the edge juice, how could i tell if i have aftermarket t/c and others done to it?

 

I've replaced my trans and ended up going all in, but every shop I talked to the first thing they recommended was a new pan because it would add strength to the transmission and keep it from twisting and if you didn't at least change the pan they wouldn't touch it as far as upgrading anything else. So from my experience if you have the stock pan you have a stock transmission

 

I wouldn't use that as a "rule of thumb"

Throw some 150hp injectors in it, if it slips, well, it's stock

 

Well its on level 4 now haha
