Have a stock automatic transmission for a 97 lt1 and my shift solenoid keeps going out i have replaced it once and it lasted about two months and now my car wont shift out of second im stumped on whats causing this

 

I'll move this post to the "Drivetrain" forum. Lot's of smart 4L60E people there.

 

What if any code are you actually getting for the solenoid the actual code number?
