Shift biased detent profile

Abstract

A detent assembly for a transmission is provided including a transmission component, such as a shift rail, movable between a plurality of shift positions including first, second, and neutral shift positions. A contoured surface on the shift rail includes first and second recesses, respectively, corresponding to the first and second shift positions. A neutral recess is arranged between the first and second shift recesses corresponding to the neutral shift position. The first and second recesses, respectively, include first and second transition surfaces sloping towards the neutral recess with the second transition surface being steeper than the first transition surface. A detent assembly includes a biasing member and a detent member with the biasing member urging the detent member into engagement with the contoured surface. The biasing member generates a first work along the first transition surface and a second force along the second transition surface greater than the first work.
