just like an engine, there is a level inside that should not be exceeded. If it is, the fluid can get whipped into foam and then you are pumping air and ATF through the trans. It can damage the bearing surfaces, but it would take more than a mile or 2...




An engine has a crankshaft with arms sticking out a few inches, like a kitchen mixer. What sticks out on a tranny shaft to beat fluid into a foam?
