i have a 03 350z performance edition and everytime i try to shift from 2nd to 3rd at high rpms the gears grind and it does it as well going from 3rd to 4th i already replaced the syncros so what else could it be?


also if anyone is interested in selling a single mount turbo kit or a twin turbo kit feel free to reply or email me at b00gi3time@hotmail.com

 

Might want to read this recent thread on the same problem:

Could be driver error
