I have a Mazda speed 3 and I need to change the transmission fluid. I friend recommended me the Motorcraft® Full Synthetic Manual Transmission Fluid XT-M5-QS but at the dealer shop the guys gave me the Motor craft® 75W-90 Synthetic Axle Lubricant XY-75W90-QLS, My question is, is this really a correct selection for my car?
