If you tap on the back of the shift motor with a screwdriver handle will it shift back to 2wd?

The transfer case has a vacum asembly on the passanger side of the case and three different plugs where there is wires coming out of them this problem started before i replaced the t.c. with a new one i have chased the vacum lines to the fire wall where there is two solinoid looking things one over the other im not sure what it is that your talking about when u say the shift motor please describe that part please?

Sorry. Was thinking of an electric shift motor. If you have a vacuum assembly you need to change every inch of rubber hose right away. Its old and can't be trusted. Little vacuum leaks add up to not working.

checked every inch of hose does not leak or have cracks used a hand held vac. pump on both sides from solinoids on fire wall neather side blead down after 5 min constant pressure un hooked elec. from solinoids and the light on dash went out on dash cluster until i plugged them back in then it came on i think its the switch itself priced one out through the dealer 187.00 got to save up for it

Nice that you have a vac pump and know how to use it. Don't have much familiarity with the Toyota systems, but I think you might be on the right track. Did you try driving it with the electric connector unplugged to see if it was actually unlocking? It could just be controlling the light.
