Greetings all,
At 70mph i engaged reverse believing it was 6th (don't ask). Every minute or so i heard a deep sounding squeal coming from the gearbox tunnel. Reverse gear had not fully engaged given the spinning internals but i guess the gear teeth were bouncing off each other. The intermittent squeal continued for another 45 min in every gear. After the engine cooled completely no more squeal was heard.
I dropped the gearbox oil. About 20/30 small metal particles (the largest around 1mm across) were found and a 12mm shaving (attached in photo).
I have a Terrain Tamer HD clutch. Its a 2011 1HZ 78 series with last gearbox oil change around 30K km ago with light use.
Do i need to drop the gearbox and check for bearing /meshsynchro damage ? Or am i good to flush one more time and carry on business as usual?
