Ford Motor Company F6RZ-7G391-A Transmission Solenoid Pack

The CD4E Transmission Solenoid Pack (F6RZ-7G391-A) is an integrated solenoid block that sits inside the CD4E/LA4A-EL 4-speed automatic transaxle’s valve body to manage hydraulic circuits for gear shifts, EPC pressure regulation, and torque converter lock-up under ECU control. It is a Ford/Mazda OEM or aftermarket replacement used in Ford Escape, Mazda Tribute, Ford Contour, Mercury Mystique, and Mercury Mariner vehicles with CD4E transmissions. Operating at 12V DC with ATF as the fluid, it features internal electromagnetic solenoids and internal mounting for valve body installation, driven by ECU-controlled on/off and PWM actuation to ensure precise shift timing.
