May have found a newer use of the Dual-Range Hydra-Matic.
US Army M114 used a 283 Chevy V8 backed by a Dual-Range Hydra-Matic. Was deployed by the Army in the 60s and early 70s, but I can't find when they were actually manufactured.

Good info Bill. This is from discussion with Pontiac Pat (Bill, you might recall e-mails with him). Pat is a '55/'56 Pontiac "expert" and a Rolls Royce "expert" (in my opinion). He has 55/56 Pontiacs, has worked with them for many years, and just purchased a '57 RR.

Don, I had the flathead reunion on my calendar and really wanted to go -- but sometimes life gets in the way of the important stuff (Pontiacs). Bummer!
Regarding the Controlled Coupling (aka Strato-Flight) HydraMatic... I was thinking of starting such a thread but waiting until I had a firm understanding of how it works. The power flow through the CC is like the dual range but the control of the planetary units is quite different and more complex. I'll go ahead and start a thread on it. |

3.08 Speedo gears for dual range in 55.2 GMC?
My truck has 3.90 gears but I’m swapping to a 3.08 rear. What drive or driven Speedo gear do I need? Can one from a car hydramatic be used? Part numbers? Thanks

I have been a fan of these transmissions since my first car, a 1953 Chieftain L8. From just reading what is written here I have learned more. I thought the reason GM discontinued the Hydra-Matic was the torque converter was better but from what you said it would seem that is wrong.
