The Ford C6 was also the first automatic transmission to be completely designed and built by Ford Motor Company. And it would eventually serve as the basis for Ford’s first electronically controlled heavy duty transmission, the E4OD. Ford E4OD / 4R100 Class lesson 1 of 16For parts and kits visit: of: transmission, work area, tools, kits and safety.

Introduced in 1989, the E4OD was Ford's first electronically controlled transmission. Based on core components of the C6, this transmission was used in many light and heavy duty vehicles including the Bronco, F-150, F-250, and F-350. While physically too large for use in most passenger cars, these transmissions are popular upgrades for older trucks and larger vehicles that were originally equipped with a 3 speed automatic. With the addition of an overdrive, increased fuel economy and a better driving experience can be had by choosing one of these units for your project. This transmission is also very robust, with power and torque handling capabilities (especially when upgraded) that make it a popular choice for diesel enthusiasts. The E4OD was produced in several different bolt patterns, which also makes it popular for a swap or upgrade. These include small block, big block (385 series, not FE), diesel, and modular bolt patterns.

Important Years

• 1989 - 1997 was the E4OD production run
• 1997 was the transition year to the 4R100 and vehicles from this year could be found with either transmission.

The 4R100 was introduced as the replacement for the E4OD and was internally stronger for use in the Powerstroke Diesel trucks. While almost identical on the exterior, not all parts are interchangeable between these two units, so care must be exercised to insure compatibility. Unlike the E4OD, these units have a dedicated output shaft speed sensor located towards the rear of the transmission. A PWM (pulse-width modulated) torque converter clutch solenoid was also added, first to 4R100s in diesel applications and later to all 4R100s.

Not all E4OD transmissions come with the gear machined into the output shaft to drive a cable-drive speedometer. In 1992, Ford started using the differential speed sensor to run the electronic speedometer in trucks and omitted the drive gear from the output shaft. Transmissions without the gear can have the output shaft changed, but complete transmission disassembly is required since the output shaft is in the back and the transmission disassembles from the front.

Early E4OD Range Sensors are Prone to Failure

E4OD transmissions manufactured prior to 1995 had an issue with the MLPS, or “Range Sensor”. It was determined to be inadequately weather-proof, allowing water to enter the connector and corrode the pins, causing electrical problems. It is always recommended that this sensor be replaced with an updated 1995 or newer style, if it has not been already.

Both GM and Ford have made statements regarding the fact that while the physical transmission was designed jointly, programming of the transmission will be unique to each manufacturer and therefore their respective powertrain configurations will not necessarily be reminiscent of each other with regard to shift strategies. The 10R80 features 10 forward speeds, 3 of which are overdrive ratios. It's deep 4.69 to 1 first gear ratio is the lowest in its class and it features a relatively tall 0.63 to 1 final overdrive ratio.

An integrated electric transmission fluid pump permits the 'start-stop' feature with minimal delay. Like the six speed 6R80, the 10R80 features three driving modes - 'Tow Haul', 'Sport', and 'Normal', with each driving mode modifying the shift schedule and characteristics to compliment particular forms of driving behavior. Because the transmission features 10 forward speeds performance and, more importantly, fuel economy is maximized by the transmission's ability to select an ideal ratio for current driving conditions, such as engine speed, load, and vehicle speed.

The 10R80 became standard on the 2017 F-150 equipped with the 3.5L EcoBoost (Raptor and standard models). As of the 2018 model year, the 10R80 is standard with all engines except the standard 3.3L Ti-VCT V-6 (2.7L EcoBoost, 3.5L EcoBoost, 5.0L V-8, and 3.0L Power Stroke diesel). A stacked numerical (1 through 10) readout in the gauge cluster identifies the currently selected gear ratio in real time.
