4-speed automatic transmission (figure 12) has electronic control. Automatic transmissions are available in two variants: 4EAT and CD4E. All models produced in 1993 (with automatic transmission) equipped with a 4EAT transmission. Since 1994, 4-cylinder models have been equipped with a CD4E transmission, while V-engine models have been equipped with a 4EAT transmission. The transmission type is stamped on a plate attached to the transmission housing.
Note: The specified transmission designations are used only by Ford. Mazda uses its own equivalent designations: instead of 4EAT and CD4E, they use GF4A and LA4A-EL, respectively. Please keep this in mind when ordering spare parts.
The 4EAT/GF4A transmission is a purely planetary design, while the CD4EZ/LA4A-EL transmission has a planetary gearbox with a chain drive and a conventional differential. In both transmissions, gears are changed using electromagnetic valves controlled by an electronic control unit. All solenoid valves are installed in the valve box.
Because automatic transmission repair requires specialized equipment and tools, this chapter covers only troubleshooting, maintenance, adjustment, and removal and installation procedures.
If a major transmission overhaul is required, contact a specialized service station. To reduce repair costs, you can remove and install the transmission yourself.
