I was shifting from 3rd to 4th at full boost and 8.500 rpm's and I heard a weird noise and then when I came to a stop I went to upshift and 3rd grinds like there is no syncro at all there is maybe 2k miles on this tranny and it is their stage3 race tranny with evo 9 gears. Does anyone have idea what mat have let go? I can still go into 3rd but like I said it grinds really bad and all the other gears are fine.
