Are your syncros getting weak? Ring and pinion failures are being traced back to the lightweight shockproof.
Not sure if the sycros are getting weak or not. I have been running the cocktail for several thousand now and no issue. Seems to work better then the amsoil and mobile one I have tried previously. but I used those on my 02 tranny, this is an 04 tranny. sorry for the newb question, but what are the ring and pinions?
