41chevy Posted April 11, 2016 Share Posted April 11, 2016 In the early 1950's GM used the experience gleaned from making their Hydra-Matic's for use in tanks( late WWII and pre Korea) to develop a practical automatic for heavy trucks up to and including class 8. . Three ranges, seven forward gears and reverse gave it 16 gear changes. Pretty interesting. Page 112 was 1/2 paragraph on warnigs about granny gear usage.
