Stupid question: how do you change tranny fluid in a 550? --Dan (will be that much less stupid when I find out - and Doody: if I have it, I will feel dumber yet )
Oh, Ali, what fluids are you using in your tranny? based on your extremely informative posts, I have decided that I will switch to 0W-40 for the motor. I will pay careful attention to rpm / pressure and start-up pressure before making a final decision. --Dan
