I just bought a Rover 8i with SRAM G8 gars box. Third gear grinds ever time I shift there. The dealer walked me through adjusting it but did nit work. I turned the adjustment on the shifter to the left many times but did not help. Tried going the opposite way but did not help either. I think it is a factory defect. Dealer advised to check in here before I bring it back. The shop is a two hour drive from my home.
