Can anyone tell me what the stopping point is before transmission upgrades. How much can the stock tranny hold over stock power. I'm looking to bolt on a ported intake, 90mm throttle body, and a reflash. Should i be worried? Only reason i say this is i just had a new transmission put in at 55,000 miles, guy that had it before me must've brake standed and not known how to drive, clutch all over the pan, and after seeing the pricetag on the new one installed i'm not taking any chances. i know a tranny upgrade is always worth it, just wanting to know some info.
