i have a 1993 6.5 5 speed with 227k miles. it pops out of 4th gear sometimes when i hit a good bump in the road and it always pops out if i accelerate in 4th gear and take my foot off the accelerator. anyone had this problem? thanks

My guess would be that either the shifting strut springs are worn or damaged or the springs in the shifting tower are worn as well.

I have a 93 with a 5-speed. Mine would pop out of gear in OD. It would do that when going down a hill and off the fuel.
I dont have that much of mileage like you have, mine is 107K. I changed the trans oil to Amsoil that is made for the NV4500. I have no more popping out of gear. Check out the web sight for Amsoil, Napa will sell you anything, beware.

If you change the oil, it will only hold 4 quarts. Cost is around $13.50 per Q.
My be worth the cost. This should be changed every 100K.
