Manufacturer	Ford Motor Company
Also called	FN4A-EL
Production	2000-present
Predecessor	CD4E F-4EAT ATX
Class	4-speed transverse automatic transaxle

The 4F27E is a 4-speed automatic transaxle for transverse engine use. It was jointly developed by Ford Motor Company and Mazda, which calls the unit the FN4A-EL.

The 4F27E is a 4-speed automatic with an added overdrive and is completely electronic, with all shifts controlled by solenoids. It has a four-element torque converter that includes a torque converter clutch and geartrain with two planetary gearsets, a transfer-shaft gear final drive, and a differential. The transaxle uses electronic shift control and is designed for operation in transverse powertrains for front-wheel drive vehicles. The hydraulic control system of the 4F27E transaxle has six electronically controlled solenoids for shift feel (through line pressure control), shift scheduling (through shift valve position control) and TCC apply, controlled by pulse-width modulation (PWM).
