Already pinched myself with the new transmission jack. Nothing like injuring yourself before even starting work on the car
Also, something really weird. When I lifted the jack up out the box, a ton of tiny ball bearings (like <1/8" diameter) came tumbling out into the box and all over my garage floor

Turns out they must be from something else. There were several holes in the box (though it was in good shape for the most part considering the contents), so I assume they fell into the box at some point. I looked all over the jack, and there is nowhere they could have come from. I also tested the jack out, and it seems to work great
