I think they have one even cheaper than that. I got mine from them and i thought it was $99 for a 800lbs. You will probley never have that need for one that heavy duty.
I liked this one because it was so low, not necessarily the lifting capacity. I know the transmission’s not that heavy since I can lift it into the trunk of the car by myself, but I’d rather not take a chance damaging it if it falls off of a jack with a piece of wood. And the adjustability is nice when the dowel pins are being stubborn lining up.
Did you lower the transmission a little and let the motor tilt backwards (with a jack under the motor)? I use about 3 feet of extensions & a universal to get to the upper bolts.
They are the way to go. I bought one last year when I was trying out different converters last year. Trans was out and back in every weekend for 5 weeks.
