1990 K2500 Transfer Case Pops out of 2H

Greetings all. Was hoping to get some insight on an issue we're having on a NP263C Transfer case. The truck is a 1990 Chev K2500 with a manual 4x4 shifter on the floor.

We've had the trans rebuilt and the transfer case rebuilt with a rebuild kit. The problem is, the transfer case selector will randomly pop out of 2H which renders the truck into only a PTO mode. It shifts into the 4x4 gear fine but the manual shifter just pops out of 2H every now and then. The shifter is very, very loose, even though we had the transfer case rebuilt.

Does this sound like a problem in the case it self or the gear shifter is somehow bad?

Thank you for your help.
Mark

Ya, I figured he probably didn't do it right or it's an issue in the gear selector. He's no longer available.... figures.

Anyone know what might cause a very loose gear selector?
