Hey guys,

I've had my 2007 GMC Sierra 1500 Vmax for a couple years now and love it but now I have a reoccurring issue that I can't figure out and hopefully someone here knows exactly what might be wrong.

The Issue:

This will happen randomly at any given time. I'll be driving along just fine and everything will be normal. I'll come to a stop, go to take off and the trans wont shift out of first and the speedo wont move off of 0 mph.

To fix it I have to pull over and stop, shift to neutral then back into drive and everything is just fine after that until the next random occurrence.


Does anyone have any idea what this could be? When the trans does finally shift it doesn't slip or shift hard at all. No clunking, no burning smell, no nothing. I'm a bit baffled.

Thanks for the help in advance!

 

Sounds like you MAY have a VSS issue as your speedo doesnt move. Try manually shifting into 2nd gear. These tranbsmissions will start in 2nd gear if commanded to.

peace
Hog
