This Ford 4R100 transmission is remanufactured with the HIGHEST QUALITY PARTS AVAILABLE.

The Ford 4R100 transmission is a four-speed automatic transmission that was used in select Ford truck models from 1998 to 2004. It features an all-aluminum case and extension housing, along with hydraulically-controlled planetary gear sets for smooth operation. Electronic shift control allows for precise gear changes, and overdrive and lock-up torque converter contribute to improved fuel efficiency.

The specifications of the Ford 4R100 transmission include:

  • 2.45:1 gear ratio in 1st gear, 1.45:1 in 2nd gear, 1.00:1 in 3rd gear, and 0.69:1 in 4th gear.
  • It has a 6-bolt hexagon bolt pattern and a transmission length of 23.3 inches (593 mm).
  • The weight of the 4R100 transmission ranges from 200 to 300 pounds (91 to 136 kg), and it is rated to handle up to 700 lb-ft (949 Nm) of torque, making it suitable for heavy-duty applications.

The Ford 4R100 transmission was used in various Ford truck models, including the F-250, F-350, F-450, F-550, and Ford Excursion, during the years 1998 to 2004. It offered improved electronic controls compared to its predecessor, allowing for smooth shifting and torque converter lock-up, which resulted in better fuel efficiency and drivability.

Although the 4R100 transmission was eventually replaced by newer transmission models in Ford trucks, it remains a popular choice among truck enthusiasts and can still be found in older Ford truck models. Its durable construction and ability to handle high torque make it a reliable option for heavy-duty use.


  • The clutch count in all drums has been enhanced to bolster holding power and reduce the likelihood of slippage. Specifically, the overdrive and intermediate clutches now feature 3 clutches each, while the direct clutch has been augmented to include 5 clutches.
  • The pump has undergone precise machining to restore its clearances to OE+ specifications, enhancing pressure and flow. This modification addresses the typical wear issues seen with the original aluminum pump and steel gear setup.
  • For V10 and diesel applications, the torque converter has been equipped with a triple clutch and a billet cover, providing a robust solution to prevent converter failure.
  • The front and rear planetary gears have been upgraded from their original aluminum construction to a more durable 5 pinion steel design.
  • Installation of a new boost valve has been carried out to increase pressure, thereby enhancing flow and improving shift quality.
  • The valve body of each transmission has been completely remanufactured, including the addition of all-new heavy-duty springs, to address and correct any shifting irregularities.
  • Each transmission undergoes rigorous testing under both cold and hot conditions using a specialized dynamometer testing program. This program utilizes fully synthetic automatic transmission fluid and incorporates a filtration system to ensure optimal performance.
