Has anyone else’s fusion shifted slightly rougher after changing the trans fluid? I changed my fluid about three weeks ago at 61000 miles and then again yesterday at 64000 miles. I noticed it has a little bit more of a jerk into some of the gears but maybe I’m not accelerating fast enough when it goes to shift? I hear a faint whine while slowing down but that’s it. No whine ok acceleration or at cruising speeds so I don’t think torque converter. Fluid is still pretty dark after adding 8 quarts of new fluid after the two changes. Anyone else experience the same?
