I just picked up my new 03 CCSB in Savannah GA and trying to drive it back to Indiana. Drove great till just north of atlanta. Now it won't shift and the message center says to service brake system. Speedometer is being wacky too. I replaced the speed sensor. It was covered with shavings, pulled theTcase plug and not even a drop . Flushed it and filled it. Put new sensor in and still not working. Think the warn transfer case would cause this? Or is there someone in the area with the proper equipment to diagnose? GM was only doing oil changes today and couldn't look at it till monday, but I'm 11hrs from home!
Think it could be the TCM? I wish I had brought proper diagnostic equipment. Any help is much appreciated!
