It probably does have 4.5 quarts in it, but it is 4.0 quarts new stuff, 0.5 quarts old stuff.fullarmor2 said:They said it would only take four quarts. And dont worry that its a half quart lower. They said it would run over if they added more. My question is if this transmission is suppose to have 4.5, what is the problem? Am I ok with only four quarts?
