my car would grind 2nd gear if it hit it fast no slammin it but just a fast shift and from a stop if i put it in 1st it would kinda bang like the clutch isnt dissengaging. well i just installed a firewall adjuster and quadrant and i can shift fast without it grinding but i cant slam it because it grinds. i thought it was syncros but it will do it in 3rd 4th and 5th if it hit them hard. it cant be syncros. not for all the gears
