I hope this is in the right location. Truck is a 96 Tahoe 4x4.
Today when I got in the truck for lunch, as I was leaving the parking lot I noticed that it wasn't upshifting. The speedometer was also dead on zero. I tried manually shifting to second and third and the transmission held normally in those gears- it just didn't upshift when it was in O/D. Suddenly the speedo started working and the transmission started behaving normally. Then when driving around I noticed the antilock brakes engage briefly once or twice.
I have a feeling It's a bad speed sensor. Is there one on the transfer case? Would this be it, or would it be one on the hubs? Not sure where to start.
Thanks very much!
