Does the shift display work--?? Most common problem for most 5 speed trans, is the NSBU switch. They get water and short out.

Of course the correct code [TCM 173--???] will help diagnose the problem.

Check fluid level.

Mine did a similar thing yesterday morning, started the truck, let it warm up for 10 min, put it in reverse and had barely any power, put it in drive and had barely any power, my CTS said I was in 5th gear, truck would not shift and I had the PO700 generic code which would not clear. Pulled the battery cables and it started to act just fine, CEL was still on. Went to start it up this morning and the CEL is off, no codes and everything seems fine.

I have a feeling it had to do with the cold weather and parking on a hill, maybe it caused a solenoid to be a little sluggish and freaked out.

my trans cooler was leaking a little, can you elaborate a little mike on why you think that? i know you are the tranny guru, so i would love to understand why this issue is happening and not just how to fix it. Thanks guys!
