95 Yukon Transfercase Issues

[GalDemSuga]

Folks

I'm having some TC issues. Truck jumps out of 4-lo and when going over rough terrain, its jumps out of 2-hi. It stays in 4-hi just fine. Whats could be the cause.

Its a 350 TBI 4l60E and np 241.

If its a manual shift your mounts could be broken (Or old)allowing the T-case to move around and pull it out of gear. Check your t-case mounts, motor mounts and even the body mounts. If its electric shift youve got bigger problems.

Its manual. I will look at the mounts to see what condition they are in.
