Well i sold my lift today

How is that to work around? Transmission install, removal, etc. is the car shaky at all and how many inches are you from the floor. Can you stop it at any height? Thanks.
It is very easy to work under, wide open access to the underside of the car. It can be stopped at any point in it's travel, but the locks have only 2 positions, about halfway and full lift. I generally use a small wheeled stool to roll around on when I'm working under the car. It is as solid as any 2 post that I've ever used in my days as a mechanic, as long as it is properly anchored to the floor, and the floor is thick enough to support the load. I have left cars up on it for months at a time, never a problem.
My garage has a 10 ft ceiling so I did not see a need to buy a full size lift as I could never lift anything more than about 5 ft anyway. I have read that some buyers found the hydraulic hoses to be of poor quality, but I have been using mine as delivered since 2013. The only minor annoyance I find is having to bleed the cylinders if I have disconnected the lines for any length of time, they have a coupler similar to those on air tools.
It lifts high enough to remove/install transmissions with a typical transmission jack, I have done a few of them, my Bronco was the only one that I had to use blocks between the pads and the frame for an extra 4 inches of lift, which put the roof of the truck a few inches from the trusses. It was one of the best things that I have ever bought for myself.
