Transmission Problem

[matthud]

When I am engine breaking in 2nd gear my transmission kicks out of gear into neutral, or at least out of gear enough to grind the gears. This seems only to happen in 2nd. Like when I am driving down a slight hill and I want to maintain a speed, I take my foot off the gas and try to slow down, after a little bit of this it pops out of gear. It also happened when I was in 2nd slowing down to turn of a main road into my neighborhood, I took my foot off the gas to slow down and once again it popped out of gear.

What is causing this? Is it a linkage problem? Worn gears? Or some kind of detent/interlock issue?

It may be as simple as worn linkage or the linkage needs to be adjusted; if that's OK, it's probably time for new synchros, or could be worn engagement teeth on the gears or sliders as well.
