what gear does it slip in?
does it not shift..or does it slip like into neutral?
do you know if you have the 4l60 or 4l80 transmission?
it pulls out in second gear and when you let off the gas it seens like it goes into neutral because there is no hold back. not sure if it is the 4/60 or 4/80 it has overdrive and is a 4wd if that helps
does the engine light stay on?if so,can you give me the computer codes?
does the speedometer work?
this sounds as if you have a bad 1-2 shift solenoid,,but,it would be a good idea to replace both solenoids while you have the pan off
