In 1993 Mazda and Ford redesigned the 4EAT-G/G4A-EL. The number of solenoids was raised from three to seven, the seven solenoids, the vane-type pump was replaced by a rotor-type pump, and there was no longer a throttle cable. The transmission was renamed 4EAT and GF4A-EL.

This is a completely computer-controlled transaxle. There is NO throttle cable. Line pressure is solenoid controlled. The converter clutch is applied with the use of a typical on/off solenoid and a pulse-width- modulated (PWM) solenoid. The PWM solenoid controls the feel of both the apply and the release of the TCC.

In 1993, this transmission was used on both the 2.0L I4 and 2.5L V6 in the Ford Probe, Mazda MX-6, and Mazda 626. In 1994, the 2.0L I4 engines got a new transmission, but the 2.5L V6 continued using the 4EAT/GF4A-EL.
