I've got some noise coming from the manual tranny in 1st, 2nd & 3rd gear. No noise that I can tell in 4th or 5th gear. Tranny fluid checks out fine, no metal shavings either. Truck has 101k on it. Shop says tranny is probably going out. Anyone else have a manual tranny go out on their T? Did you rebuild, get remanufactured or go to salvage yard?
