![]() During the test, use common sense safety practices and redundant measures (chocking all wheels and setting the parking brake for the stall speed test, for example) to reduce the risk of personal injury and/or vehicle damage. If any range does not fall within spec, repairs are necessary. This test places tremendous strain on the transmission and therefore is highly time sensitive.Ĭompare the results of the pressure test to the Ford spec from the chart above. When performing the test, do NOT hold the accelerator pedal for more than a few seconds - severe transmission damage may occur. Once the engine speed (RPM) reaches an equilibrium state and is no longer increasing (indicating stall speed has been achieved), read the pressure and release the accelerator pedal. The stall speed test requires briefly depressing the accelerator pedal to the full throttle position. If the transmission fails the idle pressure test, do not perform the stall speed test - not only can severe transmission damage ensue, but there is no need to perform the test if any of the selected ranges fail the idle test. The idle pressure test should always precede the stall speed pressure test. The line pressure port is located on the driver side of the transmission just above the lip of the transmission fluid pan and roughly centered between the transmission input and output. Pressure specs are NOT application specific and are applicable to all 4R100 transmissionsĬhecking the line pressure on the 4R100 requires installing a transmission pressure gauge (minimum 300 psi) at the line pressure port. Parts between gas and diesel, F-150 and Super Duty applications may not be interchangeableġ000 lb-ft nominal max input torque capacity.Accumulator Body Repair Fits all E4OD, 4R100 1989-on Transmission Removal Not Required.

And even though the 4R100 is designed similarly to the E4OD, the components of the two are not interchangeable.1999 -2003 Ford Super Duty w/ 7.The 4R100 was largely introduced because of Ford's need for a heavy duty transmission that could handle the torque output of the evolving 7.3L Power Stroke. The aftermarket has proven to be a fortunate resource offering a multitude of solutions for 7.3L Power Stroke owners wishing to increase the 4R100's torque capacity. The 4R100 was a reliably proven transmission at stock performance levels but as owners began to significantly increase torque output levels, the 4R100 became a "weak link" in the drivetrain. The replacements were the 6.0L Power Stroke engine and the 5R110W TorqShift transmission. The 4R100 transmission was phased out in combination with the 7.3L. It was mated to the Power Stroke 7.3L diesel engine up until the 2003 model year trucks. ![]() To view all locations and partners, please visit our national directory.ĤR100 Transmission The 4R100 automatic transmission manufactured by the Ford Motor Company replaced the E4OD transmission in 1999 for the Ford Super Duty.
