New transmission designations will indicate (in sequence) the number of speeds, type, series, and major features (if applicable) of each transaxle or transmission. New designations of transmissions will be used throughout this section. Use the HYDRA-MATIC PRODUCT DESIGNATIONS tables to cross-reference each new designation.
