2010 Chevy Cobalt LT sedan trans 4T45E wont move after transmission rebuild.

Chevy Cobalt

Big hole in Transmission pan, drove it home full throttle, I replaced the pan,and gasket and filter,fluid,But noticed that the trans bands intermediate and reverse were burnt because of what I found in the old trans pan. replaced both bands,and replaced pressure sensor solenoid valve-out put speed sensor, problem now it will not recognize any gears.runs great no noises,the only way the thing will work is by applying the brakes , reverse lights work.its on a 2010 Chevy Cobalt , Transmission is 4T45E, please help it won’t move when giving it has.

I worked before and now it doesn’t. So the first thing to do would be to double check your work and see what is no longer in the right place. Check for anything left unplugged as well. Scan for any trouble codes present that might help narrow down the problem area. No quick fix for this one.
