Technology has changed so much there isn't much of a comparison. The TH series is far superior. Les hp loss, improved shifting, and durability. Rebuilding the hydramatic is rapidly becoming a lost art, it's been over 40 years since GM produced the tranny. If you figure a service life of ten years, the mechanics that worked on them regularly are at least 60 by now.
