Am I Asking for Troubles ?????
I have been told by the shop doing the mods that the stock trans is capable of handling the power and abuse I am planning. Is it realistic to expect that with the numbers I am posting above the trans will hold up without further upgrades. I know sooner of later I will need to do a rebuild but A few years out of the stock unit would be nice.
I cant answer your question about th elife of your tranny though. It seems to be on an individual basis that they last or dont. I can suggest not making repeated passes with it on the street, as I think this hurts more than anything.
