4R55E Master Rebuild Kit 1995-96, new and ready to install. Fits the 4R55E. Ships fast from the USA.
This kit is for the two-wheel-drive version of the first electronic Ford four-speed, the 4R55E, as built for the 1995 and 1996 model years. It covers the rear-drive Explorer and the 4.0L Ranger and Mazda B4000 pickups of that era. If yours slips out of overdrive, flares between second and third, or engages reverse slowly and you are taking the transmission down for a full overhaul, this set covers the wear parts: friction plates and steel plates, sealing rings, seals, gaskets and O-rings, a 2WD filter, a new intermediate band, a pump bushing and an extension housing bushing.
Ford created the 4R55E for 1995 by putting full electronic control on the A4LD. It is the heavy-duty partner to the 4R44E and sits behind the 4.0L V6. Gear changes come from clutch packs working with three bands, and line pressure is set by the computer through the electronic pressure control (EPC) solenoid instead of a vacuum modulator. A master kit renews the parts that wear out together at high mileage. That includes every clutch pack, every rubber seal and the sealing rings that hold pressure in the drums. Steel plates are included, so you are not stacking new frictions against heat-checked steels. Of the bands, this level of kit includes the intermediate band, the one behind the classic 2-3 flare, so inspect the overdrive and reverse bands and their drums before you reuse them.
Sonnax links several of these complaints, including delayed reverse and flares, to leaks in the EPC circuit and wear at the intermediate servo bore. That is why the valve body gets checked during the rebuild as well.
Check the fluid first against our ATF color and smell chart. Dark, burnt fluid with debris means the clutches and band are done. Clean fluid with a shift complaint points toward hydraulics. A pressure gauge settles it: our line pressure testing guide shows the hookup, and Sonnax gives the targets of about 125-130 psi of maximum EPC in overdrive and up to 144 psi in reverse. If pressure is low, start with the valve body. Our harsh and delayed shift walkthrough covers the same valve body family.
Listed for the 4R55E for 1995-1996, two-wheel drive. The kit also covers the 1995-96 4R44E, the light-duty version behind the 2.3L and 3.0L, because it shares the same internals. The included filter is the 2WD filter. Four-wheel-drive trucks use a different tailshaft and filter, so a 4x4 needs our 1994-1996 4x4 master kit instead. For 1997 and later units, including the 5R55E, use the 1997-up master kit. A 1994 truck still has the A4LD, which is a different transmission. Check the identification tag on the case and the drive type before you order. If you are not sure, send us the year and VIN, or browse the 5R55 family collection.

No. This set includes the 2WD filter. Four-wheel-drive 4R55E units use a different tailshaft and filter. Order the 1994-1996 4x4 master kit for those trucks.
Yes. The 4R44E and 4R55E share the same internal parts in these years, and this kit is listed for both. Match the 2WD drive type and the year on your case tag.
Steel plates are included, and so is a new intermediate band. The overdrive and reverse bands are not part of this kit. Inspect their linings and drum surfaces, and replace them if they are glazed or worn.
No. Ford revised the unit for 1997, and the 5R55E arrived that year. Use the 1997-up master kit for 1997 and later trucks.
Ford specified MERCON automatic transmission fluid for these trucks. Check your owner's manual for the exact spec for your year, and refill after the cooler has been flushed.
Inspect the pump, the center support and the intermediate servo bore. Also vacuum test the valve body and test the EPC solenoid. Leaks in the EPC circuit can burn a new band quickly.
