I just bought a 2002 camaro z28. It has a 4000 stall on it. Runs and looks great but im having a problem with a Selonoid B stuck on code. I dropped the pan and replaced the selonoid but the check engine light came back on not even 15 minutes later after finish. Anybody got any ideas? Open to any suggestions. Thanks Robby.

 

Could be that whatever the solenoid is moving is stuck, or the wiring to the solenoid is bad.
