The problem I had with my first trans jack was to get the car high enough to get the jack and trans out from under the car then there wasn't enough lift to get the trans up high enough to bolt back up. The one I have now will lift 30 inches from floor to bottom of pan. I made 14" high boxes that the tires set on, no jack stands. Strips front and back to keep from rolling off.
Still a pain at 69.
Lifts a Black Hawk big truck type.
