Starting to develop a 4th gear grind from 3rd to 4th, 5th to 4th is fine. Only happens after the car is fully warmed up. I believe a more viscous MT fluid will rid me of this nuisance, however, I don't want to swap the rear diff fluid to a thicker fluid. Is it recommended or required that those two fluids match in weight?
