Beschreibung
Zusammenfassung:	A powertrain having a controller for limiting the torque and power inputs to a transmission as determined by operating parameters and design features of the transmission. These parameters and design features include torque limits for various components in the transmission, torque ratio of the torque converter, the design K factor of the torque converter, gear ratios of the transmission, operating condition of the torque converter clutch, and input power limits for the transmission. A programmable digital computer includes a subroutine that evaluates and establishes torque limits and input speed limits from the design features and operating parameter. The controller sets the limits for each transmission ratio including reverse such that a family of transmission can be coupled to a single engine design without overpowering the transmission should the engine be capable of greater output power than the transmission can accept.
