Well, I'm gonna be on the opposite side of the street with this one. Maybe they improved on the design of these things, when i owned one, bought one, 10 years ago, but it was the most worthless piece of schlitz that i bought from Harbor Freight. It wouldn't handle the Mopar 4 speed trans that i tried using it on. I give it a thumbs down.
I borrowed one from my friend and it was cake to put the 4-speed into my car.
