SO i have a 4l60e in my daily, i installed a sonnax performance pak yesterday and now it will go into the selected gear but it wont put any power into it until 3000 rpm and then only shakily. any thoughts? i put about 4 quarts of fluid in and let it run with it in it. its my daily, i have a buick i can drive but i need this fixed ASAP so i can have my car back and get to work on the cam.

also, idk if this is the right forum, i didnt see a trans forum and if so if a mod could move this.
