93 T4R Transfer case help!

[volt110]

New to forum, I need help with this one. 93 with the 3.0 six, auto. Last week while going into 4L, everything okay. Went to go back to 4H and 2H she wouldn't move! Long story short, will drive and shift only in 4L. Everything else seems okay. Any suggestions where to start on this one? I just purchased service manuals, but still waiting on electrical service manual to find all of the switchs on the transfer case.

TIA,
Ed

Update:
Having manuals in hand, I reviewed the relays and switchs. Last item to check this weekend is the plug end at the ECU. Still open to any thoughts? Last experience with our folks at the local Toyota Dealer was $$$.

How does it shift between 2h 4h and 4l at the transfer case...solenoids?

If so, maybe the solenoid(s) are bad or out of adjustment...

Thanks for the response. I marked the location of the slector switch and then loosened the jam nut on the selector switch next to the transfer case, and check the shift with an adjustable wrench. It was smooth and positive. I checked alignment of the selector switch per the manual, and tightened everything back up. Still no joy. Today, I am going to the end of the plug for the selector switch to the ECU and check the operation of the switch that feeds the signal to the ECU. I hope it is a simple as a bad switch. BTW she has 190,000 miles on her, and she pulls strong. This is the first head scratcher I had with her. I will let you know how I make out.

Thanks again,
Ed

okay, transfer case is toast. Now, I have found one out of a 97 Limited Edition. Good condition, 60k auto, 3.0ltr. Does anyone know or have a source to see if this will fit a 93 of the same configuration?
Any help on this would be greatly appreciated. Winter is close, and would like to get my T4R back on the road.
