In this video I repair a Tuff Torq hydro transmission out of a John Deere Z930M. The issue was that once the transmission got warmed up it would start loosing power. The longer it ran the weaker it would get.

In another video I show how to remove these hydros from the John Deere Z900s

I also have a video showing how to do an oil and filter change on these hydros.
