Okay, i have a '97 Silverado 2500, Its a big block truck with the 4L80E. Im not sure what the transfer case is but i suspect its a NV243 because the truck is push button 4x4 and thats what gm indicates. The problem is when i go to put it in four wheel drive it just wont actually go, the light repeatedly flashes but it just wont engage. Im having a time finding any information on the four wheel drive system in general and was hoping someone would have some insight or be able to tell me if the push button systems in these trucks had and notorious problems that may fit my problem.
