(I think this is the spot to put this or if not in interior)
I have a 1989 c1500 it’s has a 700r4 trans, but my speedometer works for 5 minutes then quits but as soon as you shut off the truck and turn it back on it works for 5 minutes then shuts off, leaning towards a speed sensor that is at the tail of the transmission or a loose ground/bad ground, if y’all could give me some more options or help me figure this out it would be helpful.
