I just picked this truck up. It is a 460 auto overdrive truck. It was running driving and shifting fine for the first few hundred miles that I drove it. This morning with my wife driving the transfer case popped into neural.At least that is my assumption. I went to check it out after moving the transfer lever in and out of high a couple of times the truck would go into gear again. Now it will not shift at all if I put it in drive. If I start out in first I can shift to second but when I shift into drive it don't seem to go completely in ? Thanks in advance for any help.
