Abstract: A method of controlling a transmission includes determining if the transmission is currently executing a first torque controlled shift from a first gear ratio to a second gear ratio. A torque controlled shift is defined as a shift control operation in which the speed of the engine is controlled to perform a shift operation. When a second torque controlled shift is detected while the transmission is currently executing the first torque controlled shift, a dual torque controlled shift strategy is executed, which merges a first shift control strategy for executing the first torque controlled shift with a second shift control strategy for executing the second torque controlled shift. The dual torque controlled shift strategy seamlessly executes the first torque controlled shift and the second torque controlled shift without a time delay and engine torque disruption therebetween.
