4R55E Overhaul Kit 1995, new and ready to install. Fits the 4R55E. Ships fast from the USA.
A 1995 Explorer or 4.0L Ranger that puddles fluid under the transmission, hesitates before it pulls into reverse, or has started to flare between gears is usually telling you the seals have hardened. This is the TSS S27900H overhaul kit catalogued for the 1995-1996 electronic four-speeds in this Ford family: the 4R55E behind the 4.0L V6 and the 4R44E behind the 2.3L and 3.0L, along with the A4LDE label some catalogs use for the same years. It is the gasket and seal set a rebuilder reaches for when the unit comes apart, so a 1995 truck goes back together with fresh sealing everywhere.
The 4R55E grew out of the A4LD and keeps its basic hardware: a front pump, clutch packs for forward, reverse and overdrive, and bands held by servos, all applied by line pressure. What changed with the electronic version is control. The powertrain computer sets line pressure through the EPC solenoid and decides each shift with solenoids in the valve body. That control only works if the pressure stays where it is sent. The gaskets at the pan, pump and valve body, the piston lip seals in each drum and the sealing rings on the rotating shafts are what hold it in. A 1995 unit has lived nearly three decades of heat cycles, and its rubber has lost the stretch it needs to seal at idle when pressure is lowest.
Start with the fluid. Clean red fluid and a leak point to seals; black, burnt fluid and clutch material on the magnet mean the frictions are gone and the 1995-1996 4R55E master rebuild kit fits the job better. For slow engagement or slipping with good fluid, put a gauge on the line pressure tap and compare each range, as our line pressure testing guide describes. Low pressure in every range points to the pump or EPC side; a drop in one range points to a single seal or sealing ring. Our 4R55E problems and cost page covers repair-versus-replace math.
This listing is for the 1995 4R55E. The TSS kit is catalogued for 1995-1996 A4LDE, 4R44E and 4R55E units in the 1995-1996 Ranger and Explorer, and the 1996 Aerostar, in two- and four-wheel drive. Mazda B-Series trucks of the same years use the same transmissions. Do not use it on a 1997 or later unit: Ford converted this case into the five-speed 5R55E and 5R44E that year and the later seal set is different, so a 1997 truck needs the 1997 4R55E overhaul kit. A 1995 4.0L should read 4R55E on the door tag transmission code and the case ID tag; send us your year and VIN if you are not sure. More kits are in our rebuild kits collection.

No. An overhaul kit is the gasket and seal set: gaskets, O-rings, lip seals and sealing rings. If the clutches are burnt or the steels are blued, step up to a master rebuild kit for 1995-1996.
Yes. The kit is catalogued for 1995-1996 4R55E and 4R44E units, so a 1996 Explorer, Ranger or Aerostar with the four-speed automatic uses it as well. 1997 and later units take a different kit.
They share the case design and the seal kit, but the 4R55E was built with stronger drive components for the 4.0L V6. Smaller-engine Rangers and Aerostars got the 4R44E. Check the door tag transmission code to confirm which one you have.
Use the automatic transmission fluid type printed on the dipstick or in your owner guide for that year. Check the level hot with the engine running in park on level ground.
Inspect the pump bushing and stator area, test the EPC and shift solenoids, replace the filter, and flush the cooler. A pump that is scored or a weak EPC solenoid will cause low pressure even with new seals.
