Anyone have any experience on manual gearboxes..? My '02 Colorado GX (1KD-FTV) with manual box has started to "grind" when shifting to second gear out of the blue. Mr. T replaced the clutch (+ release bearing, etc.) about 5000miles ago with a genuine part so the clutch is working fine in my opinion.
I've replaced the gearbox & transfer case oil yesterday to make sure the oil and oil level is not the problem, but the issue still remains... Stationary or at slow speed/rev's all is fine, but at higher rev's/speed there is this grinding sound if you try to shift to second gear. Only second gear - the others are fine. Seems a bit worse down-shifting, but I guess that is due to the higher rev's/speed. I guess if you want to force it into gear it will still go, but I'm just nursing it now and try to avoid second alltogether...
In my opinion all the signs point to the syncro on the second gear (which I really hope it's not...) Any ideas, advice or tests I can do to try and pin-point the problem before starting to take the gearbox apart?
Many thanks in advance!
