The N4A-EL is a four speed overdrive transmission with shifts and shift timing being controlled by the on board EC-AT control unit. The torque converter is equipped with a lock-up mechanism and is also controlled by the EC-AT control unit. This converter has a stall ratio of 1.900:1.

The line pressure used for shift feel is determined by engine vacuum to the modulator, pressure regulator valve, and spring in the transmission. This transmission consists of three planetary gear sets, four clutch packs, two bands and two sprags. It holds 7.7 US quarts of Dextron II or M-III automatic transmission fluid and is currently found in the Mazda 929 and early MPV’S.
