Hey gents, I moved over the weekend and took the rig up to 70mph for the first time in four years or so. I felt/heard a little whine out of the TC on the way over. Made it home and took it on a cruise this morning and the rig popped out of gear in 2H. I pulled over and tired to put her in park and heard all kinds of grinding. I could not get her in gear in 2H and limped home in 4L. Any ideas on what it can be? I really don't want to drop the TC and hope that it could be worn detent springs/balls or something else easy. Everything is stock and its and automatic. No lift kit.
