2nd Gear grind. maybe synchros?
If anyone has any knowledge that could help me that would be great. whenever i shift from 1st to 2nd gear from 4800 RPM to redline i get a loud grind and some friction. this grind seems to happen even if the clutch is all the way in and i shift slowly it grinds but not nearly as violent but still happens. anytime i shift below 4500 rpm it doesn't grind. i drive a 2015 m235i manual trans. about 40k miles. is there any known solution to fixing the grind? it only happens 1st to 2nd ive never had it 3rd to 2nd. thinking of trying a transmission oil change and trying redline shockproof, others have used that and had success. if anyone has any thoughts on this that could help at all that would be greatly appreciated
