So just a quick question wacker. but first some background I worked for GM for over 11 years been a technician for over 17 years. . Have built more transmissions than I can remember. Before I left gm to open my own shop I was on my last class of the 10r90. Anyway. I have had so many problems with over filled transmission causing airation And over temp problems. Mainly fwd like the 6t75 .. never tired to over fill the 6l80/6l90 But I see you recomend a quart to 2 quarts over why? And have there been any problems.
