Friend of mine has a 97 Burb, 1500, 4X4, 350 (5.7L) The other day he started it and put it in gear. The truck felt like it had a rubber drive shaft. Engine would respond but the transmission was slipping. And the gear position indicator was not displaying what gear it was in. He shut it off and restarted it and the same thing. The next day he started it and the gear indicator was on, and the truck drove fine.
Any ideas?

Had the same thing happen on a 2001 Dually..........had it towed was told it was PROBABLY a rebuild (6 Speed Allison), Shop called back two days later.....................MANIFOLD PRESSURE SWITCH, transmission service.................TOTAL BILL one tenth the cost of a rebuild. I was thrilled LGK
Possibly a trans range switch, Check for some codes.
