Abstract:
A control system includes first and second clutches of a transmission and a control module. Each of the first and second clutches includes an on state and an off state. The control module cycles the first clutch between the on state and the off state using a stepped command signal while the second clutch is maintained in the on state. The control module monitors an output parameter of the transmission that is based on the stepped command signal. The control module controls the transmission based on the output parameter.
