Ok. I suspect the ATF fluid level may be a half quart to a quart overfull. So, as to the "drain and fill" method I am using.. I believe the Volvo is one of those cars that does NOT have a trans filter? So.. I drain/filled the fresh gallon of ATF about 100 miles ago (yes, 100 not 1000.) Should I drain/fill another gallon, like, the day after Christmas.. ? Or, wait another 900 miles? WWYD?
It came out looks like nasty grey/black motor oil, pretty bad. Shifts a little better with the new stuff, maybe a little smoother. I think there is more to improve.. It shifted fine to start with, but that is why we change the fluid BEFORE there is a problem with it, right?
I bought Valvoline Dex/Merc and have two more gallons of it. Used one.. making it a half quart or quart overfull...
