Can't shift into 4WD?
I think you're supposed to have your transmission in neutral whether shifting into or out of 4LO. I dont remember if it needs to be in neutral when shifting out, haven't used 4LO in a while.
Going into or out of low range you want to be barely rolling. At 5 mph it probably sounded ugly! If you find yourself stuck at a dead stop and the T-case won't shift, hold pressure against the T-case lever in the direction you want it to go and very slowly ease out on the clutch. As the input shaft starts to turn over the T-case should mesh and drop into gear.
