I started having shiftin problems about a week ago and the speedometer started actin weird. I was told to pull the fuse to the tranny to see if it would still have 2nd, and it did, it also had 3rd, so it wasn't the tranny. It all turned out to be speed sensor in the transfer case. So if anyone is having this problem, u might check ur speed sensor, it cost $100 from Napa, it took me 3 minutes to change it, all u need is a 1" wrench. I just figured someone else on here has probably had the same problem as me, so I figured I'll tell everyone how I fixed it.
