Claim:
A transmission for a vehicle comprising: a first gear set including a first plurality of gears; a second gear set including a second plurality of gears; a first plurality of elements operable in an applied state to selectively engage selected ones of said first plurality of gears and operable in a released state to selectively disengage selected ones of said first plurality of gears; a second plurality of elements operable in an applied state to selectively engage selected ones of said second plurality of gears and operable in a released state to selectively disengage selected ones of said second plurality of gears; and a controller in communication with said first plurality of elements and said second plurality of elements and operable to toggle said first plurality of elements between said applied state and said released state and operable to toggle said second plurality of elements between said applied state and said released state to provide the transmission with a desired gear ratio, said controller timing entry of at least one of said first plurality of elements and said second plurality of elements into said released state with entry of at least another of said first plurality of elements and said second plurality of elements into said applied state by controlling a hold pressure applied to said at least one element entering said released state, said controller determining said hold pressure by referencing current operating conditions of the transmission in a lookup table stored in a memory of said controller.
