4R44E Overhaul Kit 1994-1996, new and ready to install. Fits the 4R44E. Ships fast from the USA.
The 4R44E is the automatic behind the 2.3L four-cylinder and 3.0L V6 in four-wheel-drive Rangers and Mazda B2300 and B3000 pickups from the first years of electronic control. These are light trucks that often spent their lives on farms, job sites and trailheads, and by now most of them are leaking at the pan and tailshaft, slipping on the 2-3 shift, or slow to pick up reverse. This overhaul kit is the 4x4 version, and it goes past a basic gasket set: along with the seals and gaskets it carries BorgWarner frictions and steel plates, all three bands, a filter, and the pump and extension housing bushings, so one box covers the whole teardown.
Ford created the 4R44E for the 1995 model year by giving the old A4LD full electronic control, and Sonnax notes it launched first behind the 2.3L and 3.0L engines. The number tells you its job: four speeds, rear-drive or four-wheel-drive, rated for about 440 lb-ft after converter multiplication. The geartrain uses clutch packs plus three bands, and every one of those apply circuits depends on a rubber or Teflon seal holding oil. Line pressure itself is set by the computer through the electronic pressure control (EPC) solenoid. When piston seals harden and sealing rings wear, pressure bleeds off before it reaches the clutch or servo, which is why an old 4R44E slips even when the frictions still have lining left.
That is the point of the overhaul: renew every seal, gasket and O-ring so each circuit holds pressure again, and replace the wear parts that ride on those circuits at the same time. The Transtec soft parts set covers the sealing side, while the BorgWarner clutches, steels and the intermediate, overdrive and reverse bands cover the friction side.
Not every one of those complaints means a full overhaul. Sonnax traces delayed reverse, 1-2 and 2-3 flare and harsh shifts after a forced downshift to leaks in the EPC circuit and a sticking EPC boost valve, and the same circuit can break bands and blow servo seals. Loss of fourth can come from a worn coast clutch shift valve bore. So test before you tear down. Put a gauge on the line pressure port as shown in our line pressure testing guide, and use the harsh and delayed shift walkthrough for this valve body family. Low pressure with clean fluid points at the valve body or EPC; good pressure with slipping and burnt fluid means the clutches and bands are done and this kit is the repair.
The listing is labeled 1994-1996, but Ford introduced the 4R44E for 1995, and most 1994 trucks carry the A4LD instead, which has no EPC solenoid. In practice this kit fits the 1995-1996 4R44E in four-wheel-drive Ranger and Mazda B-Series pickups with the 2.3L or 3.0L. It is the 4x4 kit, because four-wheel-drive units use a different tailshaft housing, so the rear bushing and seal suit the transfer case adapter rather than a 2WD tailshaft. If you only need frictions, steels and seals without bands or bushings, compare our 1995-1996 4R44E frictions and seals kit. Read the tag on the case, or send us your year and VIN and we will confirm. The full family is on our 4R44E and 5R55 parts page.

No. Along with the Transtec seals and gaskets, the kit includes BorgWarner frictions and steel plates, the intermediate, overdrive and reverse bands, a filter, the pump bushing and the extension housing bushing.
Probably not. The 4R44E started in the 1995 model year, and most 1994 Rangers and B-Series trucks have the A4LD. Check the transmission tag or send us the VIN before ordering.
This is the 4x4 version. Four-wheel-drive units use a different tailshaft housing, so the rear bushing and seal are for the 4x4 case. Send us your year and VIN and we will match the right kit for a 2WD truck.
Yes. Sonnax links EPC circuit leaks to delayed reverse, shift flares, broken bands and blown servo seals. Air test the EPC circuit with the valve body bolted on, and repair or replace the valve body if it leaks.
Use the Ford MERCON-type ATF listed in your owner guide. Soak the frictions and bands in it before assembly and check the level at operating temperature.
