The 4R100 reflected Ford's new identification system for its transmission lineup, but it also solved some problems associated with the older E4OD. While the E4OD's problems were not major or widespread, the Ford eyed the new 4R100 with the plan to solve these bugs. 4R100 Transmission Solenoid Pack Assembly 1998-2004 F250 F350 F450 4R100 Transmission Solenoid Pack Assembly 1998-2004 7.3 LITER DIESEL TRUCK 1.0 out of 5 stars 1. Ford E4OD and 4R100 Transmission information. 1989: Ford introduced the E4OD transmission in F series trucks and E series vans. The E40D transmission was available in F150-F350 trucks, full size Bronco SUV and E-150-E350 Vans. The E4OD transmission is a C-6 automatic transmission with electronic controls and an overdrive gear. FORD 4R100 The Ford 4R100 transmission is an updated version of the E4OD and was first introduced in the 1999 model year, and is currently found in the F250, F350, F450 and F550 Super Duty trucks, E150, E250, E350, E450 vans and the Expedition/Navigator/Excursion vehicles.
Electronically Controlled
4 Forward Gears
OD = Over Drive
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.
E4OD / 4R100 Specs
- Weight: 270 lbs. (dry with converter)
- Case: Aluminum
- Fluid Capacity: 18 quarts Mercon V (total with torque converter)
Gear Ratios:
- 1st: 2.71
- 2nd: 1.54
- 3rd: 1.00
- 4th: 0.71
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
4r100 Built Transmission
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.
