Re: pulling a engine
...It's FOUR bolts in the back of the bellhousing, much less weight.
There is no way on Earth it's easier to pull them both.
4 bolts + 2 motor mount bolts, lines, wires, and it's out, no weird angles to deal with, much easier to mount on stand right away.
I would have to completely remove the headers to pull the trans and motor out in my car, or the hoist would topple over, it's not cheap, just can't extend the legs enough.
If you were doing trans work, which your not, def pull them both, working on the trans from the underside is a pain.
