E4OD Master Rebuild Kit 1989-95, new and ready to install. Fits the E4OD. Ships fast from the USA.
Owners of early E4OD trucks usually land here after the same story: a 7.3 diesel, 460 or 351 in an F-Series, Bronco or E-Series van, years of towing, and now a transmission that slips into fourth, smells burnt, or drips from more than one seal. This new E4OD master rebuild kit for 1989-95 covers the first generation of Ford's electronic heavy-duty automatic, so a builder or a determined owner can overhaul the whole unit in one pass.
Ford built the E4OD from a C6-style case and added an overdrive section with its own overdrive and coast clutches, all controlled by the engine computer through a solenoid block on the valve body. Every one of those clutch packs is applied by fluid trapped behind seals, which is why an E4OD with hardened seals feels like a worn one: pressure bleeds off before it can clamp the frictions. A master kit puts new frictions, seals and gaskets through the whole unit at once. The listing photos show what this kit contains, so check them for steels and a filter as you plan the job.
Pull codes and do the electrical checks first; early E4OD shift complaints often come from the solenoid block or the case connector rather than the clutches. Then look at what the failure is. If the overdrive section is blued or the planet is damaged, the cause is often lube starvation, not tired frictions, and our E4OD rebuild wear points guide covers the melted front lube valve, the walking overdrive snap ring and the leaking center support that soft parts alone will not cure. If the shift complaint is a soft or missing gear with clean fluid, read the E4OD valve body testing guide first, since bore wear there outlives any clutch kit.
This kit is listed for the 1989-95 E4OD. Inside that window Ford made running changes: Sonnax lists the E9 valve body casting for 1989 and F0 or F1 for 1990-95, and splits the solenoid block, rear case bushing and pump gears between 1989-94 and 1995. Transmission Digest warns that mixing E4OD components across those changes causes comebacks, so a unit that was rebuilt before with used parts may not be all one year. Read the ID tag, compare your old seals to the listing photos, and send us your year and VIN if anything does not line up. The rest of the parts for this family, including late E4OD and 4R100 kits, are in the E4OD/4R100 collection.
Clean the case and every passage thoroughly, then inspect bushings, drums, the planetary sets and the pump before installing a single friction. Soak new frictions in Mercon V before assembly, set clearances on each pack to spec, and prime the pump when installing. Update the plastic front lube/drainback valve to the aluminum design while the pump is apart, and fit a locking ring behind the overdrive piston return spring. If the coast or overdrive clutch drum is worn, the E4OD clutch module for 1989-1996 covers this range, and a cooler that has carried debris should be replaced; the 1994-95 E4OD transmission cooler fits the later trucks in this window. Fill with Mercon V, check level hot, and recheck after the first drive.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 1989-95. Ford changed the solenoid block, rear bushing and pump gears for 1995, so confirm your ID tag build date and compare your old parts, or send us the year and VIN.
No. Replace the damaged planet and fix the cause, which on the E4OD is often a melted front lube/drainback valve restricting lube flow. Sonnax offers an aluminum replacement for it.
Mercon V ATF. Soak the new frictions in it before assembly and check the level hot after the first drive.
Heavy-duty Ford F-Series trucks such as the F-250 and F-350, the Bronco, and E-Series vans, behind gas V8s and the diesel. Confirm your truck has the E4OD rather than a manual or another automatic before ordering.
Only if testing shows bore wear. Vacuum test the valve body during the rebuild; worn accumulator or manual valve bores cause soft shifts and missing gears that a clutch kit will not fix.
