Re: 5R110 built trans no movement any gear!
With the engine running put the trans in drive, wait a couple seconds, then right into park. Does it just go into park, or is there a grinding sound? With the trans in park will the truck roll more than a foot or two?
If the answer to either of these questions is "Yes," you've just diagnosed the transfer case is the problem.
