Used this when rebuilding my 4L80e. It worked well to set the teflon o-rings in the main shaft.

It got the job done but its not that great. The tapered cones used to stretch the rings is too short, it needs to be longer with less angle so stretching is slower with less effort, I tore one using this. One of the resizers was too long to resize a ring against a drum so I made a tool, the other resizer worked properly. I'd try a different set and avoid this one.
