Summary: | A control system for a transmission coupled to an engine includes first, second, and third modules. The first module detects a closed throttle downshift of the transmission. The second module detects a request for a power-on downshift of the transmission. The third module controls a clutch of the transmission when the request for the power-on downshift is detected during the closed throttle downshift, wherein the third module one of (i) decreases a pressure applied to the clutch to a first predetermined pressure before an end of the closed throttle downshift and (ii) controls a pressure applied to the clutch to a second predetermined pressure at the end of the closed throttle downshift. |
