O.K. i have a 2003 cavy with both upper and lower motor mounts and cai and header. My ? is, is the 2.2L ecotec engine the 4T40E transmission and will the autotrans work with my car. And since i'm asking, what other things can i do to my auto tranny to improve it for extra hp and not have it blow up when i go up in hp. Thanks!
I believe the AutoTrans Interceptor and hte B&M Shift Plus are your only real upgrades. Unless you want to get your hands dirty with installing higher stall converters, etc.
