snap on makes a puller and installer for the bushing and seal wile the cost way too much to buy for a one time use many shops and most trans. shops have them you can just pay a few dollars to change the bushing it a vary easy job you just push the puller in its spring type fingers get behind the bush. and run it out with an air wrench and pound in a new one also some auto parts houses or tool rental places rent them. it's about a 5 min job with the correct tool.......ted
