Two sides of school on that. Some will say yes, others no. I'm on the keep ATF fresh, trans will last longer. That trans., to me, is like the Ford 4R70W on my truck. That trans. is good, but you GOT to change the fluid often. It likes clean fluid. I drop the 3 quarts every other oil change since 30K and now have 101K on it, this is the 4 sp AT. I'll be doing the same with our 06 5AT and hope that will keep them lasting longer. One thing on the Ody's, is that using the new VCM engine? Turning off a bank of cylinders at a time? Seems like a lot of weight for three cylinders.
