Hydra-matic Divison of General Motors?
Hydramatic Drive, perhaps?

"Hydra" and "Matic" have been used both together as one word and as two words hyphenated. GM's current website uses the hyphenated version but no mention of HMD that I could find.
At one time I think H-M was an actual division of GM but now it falls under the GM Powertrain umbrella. Any tranny techs here that have some old memorabilia around?

How about:
Hazardous Mated (to) Diesels?
