Vehicle transmission clutch engagement control system

A vehicle transmission comprising:

• an oncoming clutch having a measured fluctuating torque when disengaged, the fluctuating torque having a non-zero median value and a standard deviation;
• and
• a controller programmed t0, in response to a torque of the oncoming clutch increasing at a first rate during an engagement and surpassing the non-zero median value by a multiple of the standard deviation, increase the torque at a second rate that is greater than the first rate.

A method comprising:

• providing an oncoming clutch for a vehicle transmission, the oncoming clutch having a measured fluctuating disengaged torque that has a median value and a standard deviation;
• and
• increasing a rate at which torque of the oncoming clutch increases during an engagement in response to the torque of the oncoming clutch surpassing the median value by predetermined a multiple of the standard deviation.
