Patent ID: 6874383

Claim:
A method of shifting a vehicle transmission, comprising the steps of: (a) having at least a first shift mode and a second shift mode, each of the modes permitting a transition from a first gear ratio to a second gear ratio of a transmission; (b) electronically sensing at least one vehicle condition; (c) electronically evaluating the sensed at least one vehicle condition; (d) electronically identifying an appropriate shift mode from among at least the first shift mode and the second shift mode based on the evaluation of step (c); and (e) shifting from the first gear ratio to the second gear ratio in the shift mode identified in step (d), wherein the first shift mode permits shifting from the first gear ratio to the second gear ratio at a first predetermined speed and the second shift mode permits shifting from the first gear ratio to the second gear ratio at a second predetermined speed that is less than the first predetermined speed.
