E4OD Shift Kit 1996, new and ready to install. Fits the E4OD. Ships fast from the USA.
A 1996-or-later Ford F-250, F-350, Excursion or E-Series van with the E4OD or 4R100 that is leaking at the front seal or tail housing, losing fluid at the pan, or coming apart for a rebuild needs every soft part replaced at once. This kit is that set. It is an E4OD/4R100 gasket and seal overhaul kit listed for 1996-up units. It is not a valve body recalibration kit, despite the shift kit name on this listing, so read the contents below before you order. It contains the three metal-clad seals (front pump, rear and manual shaft), a full set of sealing rings, a full set of piston lip seals and O-rings, the valve body, pump, extension housing and center support hub gaskets, a small parts kit, and a bonded rubber pan gasket.
The E4OD is a hydraulically applied four-speed. Every clutch pack is applied by a piston, and every piston holds pressure only as long as its lip seals do. The sealing rings on the shafts and the center support hub carry clutch apply oil across parts that spin against each other, and the gaskets keep pump, valve body and lube circuits from bleeding into each other. When rubber hardens from heat and age, apply pressure leaks off before the clutch is fully clamped. That shows up as slipping and flare long before anything breaks. Heat is the enemy here: overheating under towing is one of the classic E4OD failures, and it cooks seals at the same time it burns frictions.
An external leak is easy to trace: clean the area, drive, and look for fresh fluid. Internal leaks take more care. Many E4OD soft-shift and slip complaints are electrical or valve body problems, and a gasket kit will not cure a worn solenoid body, a failed EPC circuit or a worn bore. Rule those out with our E4OD common problems guide and the E4OD valve body symptoms and testing guide first. If line pressure is correct and the unit still slips in one range, it is coming apart, and this kit belongs in the rebuild.
This kit is listed for 1996-up E4OD and 4R100 units, which covers late E4OD trucks and the 4R100 in Super Duty pickups, the Excursion and E-Series vans with the 7.3L Power Stroke, 5.4L and 6.8L V10. The 1996 cutoff is not arbitrary. Sonnax identifies the 1996-98 E4OD valve body by its F6 casting, different from the 1990-95 F0/F1 main casting, and the separator plate gaskets follow the casting. A 1989-1995 transmission needs an earlier kit. Check the valve body casting number, count your pan bolts and compare the gasket shapes with your old parts before you start, or send us your year and VIN. More E4OD parts are on our E4OD and 4R100 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Despite the listing name, the contents are an overhaul gasket and seal kit: metal-clad seals, sealing rings, piston lip seals, O-rings, gaskets, a small parts kit and a bonded pan gasket. It does not change valve body calibration.
It is listed for 1996-up units. Earlier E4ODs use different valve body castings, so a 1989-1995 transmission should use a kit made for those years.
No. The listed contents are seals, rings and gaskets only. Order a filter and, if the clutches are burnt, a friction kit separately.
Yes, the front pump seal is in the kit, and the rear and manual shaft seals are included too. You will still need to remove the transmission to replace the front seal.
Use Mercon V ATF. Flush the cooler and lines first so old debris does not reach the new seals and clutches, then set the level hot in Park.
