Pops out of 5th!

Pops out of 5th!
Help- First post and question. Have a 2002 3500 5.9 diesel with 5speed. It randomly pops out of 5th gear while hauling trailer on the interstate, mostly when I decelerate. It has a fairly new (3 years old) rebuilt trans installed. rarely does it when I am unloaded. When It pops out, I can pull down into neutral, over to left and then back to 5th and all is well. Total combined wt is only about 14,000 to 15,000 so I am not overloaded. Any Ideas?
Thanks
Thanks

Welcome to DTR. A search of "5th gear nut" should give you all the info you need. In a nutshell, the nut that holds 5th gear in place will come loose under high torque conditions. On a 3 year old rebuild, this should have been addressed but you can never tell.

It's not the nut problem . When it goes it goes. You have a sychro problem or a worn bearing on the tail shaft. When they wear they flex sometimes under the right conditions and let the gear pop out .
