hey guys i forgot...when i was at Buttonwillow track....i was getting a lot of grinding going into 4th if i shifted to quickly....now i just put in the B&M short shift kit......a few of the guys told me if i put a high performance fluid in...it might help....if i continue to grind....4ths gonna go....any help????.......everytime i had to shift into 4th..i had to push the clutch in and wait to shift so i wouldn't grind

 

Fluid will probably help, sounds like you have a lazy syncro.

 

I had this from 2000 miles. Dealer warrantee replaced forth gear.
