E4OD Overhaul Kit 1996-05, new and ready to install. Fits the E4OD. Ships fast from the USA.
If you own a 1996 or 1997 Ford F-250, F-350, Bronco or E-Series van with the E4OD and the transmission has started weeping at the pan, hesitating into gear on cold starts, or slipping on the highway once it is fully warm, you are probably shopping for a reseal. This is a new overhaul kit from Precision, supplied factory sealed in the Precision International bag, and listed to cover E4OD units from 1996 through the 4R100 years up to 2005. It is the soft-parts set a rebuilder starts with: the gaskets, rubber seals and O-rings that every circuit in the unit depends on.
The E4OD is a computer-controlled four-speed. The PCM sets line pressure through the EPC solenoid, and that oil has to travel from the pump, across the stator support and drum sealing rings, and into each clutch piston without bleeding off. Five clutches and the intermediate and overdrive bands all rely on that path. When the piston seals and sealing rings take a set from years of heat, the PCM can command a perfect shift and the clutch still slips because the pressure leaked away on the way there. A reseal restores the containment. It does not replace worn frictions, steels, bushings or the filter; those are judged on the bench once the unit is apart.
Start with codes. A 1996 or 1997 E4OD stores pressure control and shift solenoid faults that look a lot like slipping from the driver's seat, and our EPC solenoid guide walks through the resistance and pressure checks. Then put a gauge on the line pressure tap. Normal electrical readings with low pressure that will not rise under load is the classic internal leak. If the problem is limited to shift timing or a single gear, read our E4OD common problems guide first, because a connector or a speed signal fault is cheaper than a teardown.
The listing covers 1996-2005. In practice that range spans two names: Ford called the unit the E4OD through 1997, then the 4R100 from 1998 on. Sonnax groups the 1995-1998 E4OD with the later 4R100 for the solenoid block, which is part of why one soft-parts kit can reach across those years. The hard parts did change, though: the 1998 4R100 brought a revised pump, a different coast clutch drum and a PTO-capable case, and some of those details touch gasket and O-ring shapes. Check the ID tag on the driver side of the case and compare the pump and pan to what you see in the kit, or send us your year and VIN and we will confirm before it ships. Every part we carry for this family is in the E4OD and 4R100 collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, 1997 is inside the listed 1996-2005 range. Ford used the E4OD name through 1997. If anything about your unit has been swapped or rebuilt before, send us the year and VIN and we will double-check.
No. An overhaul kit is the gasket, seal and O-ring set. Frictions, steels, bands and the filter are bought separately once you have inspected the old parts.
The 4R100 is the updated E4OD and replaced it for 1998. The layout is the same, but the pump, coast clutch drum, case and converter clutch control were revised, so hard parts do not always interchange.
MERCON V automatic transmission fluid is the common service fill for this family. Fill, start the engine, cycle the gears and check the level hot in Park.
No. New seals restore pressure, but a burned or worn clutch pack still slips. If you find glazed frictions or blued steels on teardown, replace them in the same job.
