Would it be good to use High Mileage ATF in a low mileage transmission?
What does the HM ATF fluid have, besides seal conditioners, that helps the older (or newer) trannies?
I have been using 1 quart of HM with 3 quarts of standard ATF to refill my pan after I drain the old fluid (no filter change). it's a GM 4L60E tranny.
the bottle of HM says it has an enhanced additive package including seal conditioners and shear stable modifiers. And improves and maintains smother shifting longer than conventional ATF fluid.
