I just changed mine... 4Qts out reddish brown not ruby clear, and about 6Qts back in! made a NICE difference... mine didnt feel bad and shifted smoothly but at 35mph I would feel a slight bouncy looseness and I think I did feel a little shudder on throttle mostly around that same speed range... here are pics of my old fluid compared to new... I ordered the Dr. Tranny fix also that should arrive any day and Ill add that too... also ordered the conditioner... Im going to addd those items in a few weeks when I do a filter and full flush I think instead of now... wasting some $ otherwise to do it twice... for now it feels GREAT! and thats only one flush!
