    The t-case shifter lever seems as though it is too far down ie: 1/2 inch below each indication. The t-case will not stay in 4-hi. How do I adjust this??? Is it as simple as the threaded rod attached to the t-case or is it something more difficult??

    I'm assuming you have the NP208 t-case. If so, the shifter adjustment is critical. It is detailed in the manual (HELM). If not adjusted properly, the range fork will go out (I'm on about my 5th one). If you use the truck hard and it has lots of body flex, I removed the gate from the floor shifter. This way there is less chance of putting stress on the range fork. There are internal shift detents in the t-case.

    Do you have a body lift? i read on here that sometimes it messes up the linkage and it won't stay in the right gear.

    Yes it is a 208, and no there is no body lift on the Blazer. I had a quick look and could see there is a threaded rod with a linkage. I'll have a better look later on this week when I can get it on a lift.

    Thanks for the input so far.
