Control system and method thereof for multispeed transmission

摘要: An electro-hydraulic control system for a multispeed transmission having plurality of torque-transmitting mechanisms includes controller operably controlling the transmission, fluid source supplying hydraulic fluid, and being selected between an applied unapplied state to achieve ranges including at least one reverse, neutral, forward ranges. The trim systems pressure solenoids valves. may also include or more shift valves disposed in communication with capable moving stroked de-stroked positions. In any given range, only two be applied. Moreover, three are normally high solenoids, remaining low solenoids.
