The service would be the same regardless of transmission type and the manual should cover it all other than the type of oil. I’ve used Royal Purple 01303 Max Gear 85W-140 High Performance Synthetic Automotive Gear Oil in manual transmissions but let’s let others weigh in on whether this weight is good for rear ends or not.
