4R44E Overhaul Kit 1995-1996, new and ready to install. Fits the 4R44E. Ships fast from the USA.
A 1995 or 1996 Ranger or Mazda B2300/B3000 with the 2.3L four or 3.0L V6 and an automatic most likely has the first-generation 4R44E, and by now most of them are seeping at the pan, dripping from the front pump seal or the tailshaft, or taking a long breath before they pick up drive or reverse on a cold morning. This is the Precision International KP53900R gasket and seal overhaul kit for those early 1995-1996 units. It is the soft-parts set for a teardown: paper and rubber gaskets, O-rings, lip seals, metal-clad seals and the sealing rings, with no frictions, steels, bands or filter.
The 4R44E arrived for 1995 as the electronic replacement for the A4LD, and Sonnax notes it went in first behind the 2.3L and 3.0L engines. It is a four-speed rated for about 440 lb-ft after converter multiplication, with clutch packs and three bands applied by oil pressure that the computer sets through the electronic pressure control (EPC) solenoid. Every piston seal, sealing ring and valve body gasket is part of that pressure path. When the rubber hardens and the rings wear, pressure leaks off before it reaches a clutch or servo, so the unit slips or flares even when the friction material still looks usable.
The 1995-1996 units are the early style. From 1997 Ford began applying the front servo to create the five-speed 5R44E and 5R55E, and the seal kits were split: this KP53900R is catalogued for 1995-1996 only, while 1997 and later units take our 1997-2011 4R44E overhaul kit.
Pull the pan and look at what is on the magnet and in the filter. Fine gray paste is normal wear; heavy black friction material or metal flakes mean the clutches or hard parts are done and you need more than seals. Sonnax recommends an EPC air test at 50-70 psi with the valve body on the case, which finds leaking circuits before you buy anything. Our line pressure guide walks through a pressure check, and the harsh or delayed shift walkthrough covers the same family of units.
Catalogs list the KP53900R for 1995-1996 4R44E and 4R55E units in Ford Ranger, Explorer and Aerostar and Mazda B2300, B3000 and B4000, in two-wheel and four-wheel drive. On this page, that means the 4R44E behind the 2.3L or 3.0L. Four-wheel-drive units use a different tail housing than two-wheel-drive ones, so check the extension seal against your truck. Read the transmission ID tag on the case, or send us your year and VIN, before you open the package. If your truck has the 4.0L, see the 4R55E 1995-1996 overhaul kit.

No. The KP53900R is a gasket and seal set: gaskets, O-rings, lip seals, metal-clad seals and sealing rings. If your clutches or bands are worn, use the 1995-1996 master rebuild kit instead.
No. It is catalogued for 1995-1996 early-style units only. 1997 and later 4R44E, 5R44E and 5R55E transmissions take the 1997-2011 overhaul kit.
It is catalogued for 1995-1996 two-wheel and four-wheel drive applications. Four-wheel-drive units use a different tail housing, so compare the extension housing seal to your original before installing.
Yes, the front seal can be changed with the transmission out of the truck and the converter removed. Inspect the converter hub for wear at the same time, because a scored hub will cut a new seal.
Use the automatic transmission fluid printed on the dipstick or listed in your owner guide, and set the level with the fluid at operating temperature.
