Did my third trans axle service on my 96 SE with 97,000 miles today. With all the possible bad things with using MTL that can happen to the MTX, I decided to drain it and put in some ATF for the cold months to come, it was still shifting fine, besides the typical mediocre 1st to 2nd shift. The 17,000 miles old fluid came out very clean, not a speck of black sediment and odor free. It to me, smells better than the Napa brand Dexron III/ Mercon ATF, I used last week in servicing an auto trans. The same grade Quarker State ATF, I used in my car today had less of a odor to it, than the Napa brand.
I read people aren't recommending friction modifier anymore but since I had 2 ozs. sitting around and it shifts better with it, I used it.
