Shifter moving

[dendeanda]

When I go wheeling it gets pretty bumpy. When I am in 4H and I hit a pretty good bump, my shifter automatically moves to 2H. What should I do? Any help would be appreciated!

use a 2x4 to hold it in place

ratchet strap it. i used to do it on my 208 when it did that.

I think it has something to do with the mount of the transfercase, whether you lowered it or not, etc. it's a common problem i think.

I have an 84 that has done that to me and I used a bunge cord to hold it in place.

You may find that adjusting your t-case level helps. You may also find that your t-case, tranny or engine mounts are needing replacement.

I think you have an NP208 and I've no idea how them newfangled things operate.

Or you could bungee it (I did 2000 miles once with this, to keep mine from rattling). Bungee or ratchet strap is cheap and doesn't require getting under the truck

take the cover off of the shifter and grind down the shifter rail a little bit. mine did the same thing and realized that 4hi did not engage all the way. i had to grind about 1/4" so the shifter could move back a little more...it is on a 208...i have not had any problems with it since.
