I used my engine hoist and leveler last night since I was alone. It does takes longer since I have to pull it out and position it up and all. The good thing is you can get it perfectly straight and not hung up on anything at all, which is crucial when installing a twin disk. The last thing you want is the input shaft getting hung up on the disks, so you want to put the tranny on perfectly straight. Easily done with a hoist and leveller by yourself.

If I have a friend I get him to stand up top while I bench the tranny in from under the car: Lay next to trans, put trans on my chest with help from my friend, keep eyes on dowels, bench and slide tranny on while keeping eyes on the dowels. Keeping your eyes on the dowels while your underneath the car is key, it will line up and slide right on. Makes it a 30 second job. Works for me all the time.

I don't try to bench a tranny in the car with no one else around.
