Electronic Pressure Control Solenoid 4l60e

Today s electronic transmissions use a control module to control transmission line pressure shift timing and quality.

Electronic pressure control solenoid 4l60e.

Do not confuse a slipping transmission with a solenoid problem. Tcc pwm solenoid valve body. 4l60e technical information. If one or more solenoids are bad you may lose the use of one or more gears and may even be stuck in one particular gear or unable to shift into any gear at all.

It receives inputs from sensors like the maf or map vss and ect and then compares them to the information stored in its memory. Note this epc is not correct for bmw or cadillac catera 4l30e transmissions.
