mmmm Feels good getting back into wrenching... Except when I spend 4 nights replacing all the brake lines and bleeding the friggin thing just so I can test drive it, and find 4th grinds and pops out.. Does this mean my tranny is shot? I've never seen a manual die, so I don't really know what the symptoms are... 1st/2nd/3rd are fine, perfet. goes into 4th fine, but as soon as I let the clutch out, it squeals and grinds. It may not actually pop out, I put the clutch back in immediately. Truck is a 92 K1500. 4wd/IFS, 4.3l, 5 speed. ANy thoughts? Can I do something to fix it?
