4R44E Planetary 1995-01, new and ready to install. Fits the 4R44E. Ships fast from the USA.
This is a new overdrive planetary carrier assembly for the Ford 4R44E four-speed automatic, built for 1995-2001 units. The 4R44E was the light-duty version of the family, used behind the 2.3L four-cylinder and 3.0L V6 in Ford Ranger and North American Mazda B-Series pickups. If your truck whines in every gear, will not hold overdrive, or you found a loose or blued carrier during a rebuild, this is the part that replaces it. The carrier uses solid pinion pins and comes with the electric pick-up reluctor already in place.
The 4R44E grew out of the A4LD, which was the old three-speed C3 with an overdrive gearset added ahead of the main gear train. That overdrive planetary is the first thing torque meets after the converter. In 1st through 3rd the overdrive gearset turns as a unit and passes engine speed straight through to the rear section. For 4th, the overdrive band holds the sun gear and the carrier drives the ring gear faster than input, giving the overdrive ratio. The coast clutch locks the gearset for engine braking in manual ranges. Because the carrier is turning in every gear, worn pinion bearings or pins make noise all the time, not only in 4th.
The reluctor on this carrier is a toothed ring that a speed sensor reads. The 1995 update to the 4R44E brought full electronic control, and the computer uses speed sensor signals to time shifts and the converter clutch, so a bent or damaged reluctor can upset shift timing.
Loss of 4th is also very often hydraulic. Sonnax notes that leaks in the EPC circuit cause flares and delayed engagement on these units, so check pressures before you blame the gearset. Our harsh and delayed shift guide covers the same valve body family.
Check fluid level and smell first, then road test with a scan tool. A whine that follows engine speed in park and neutral points more to the pump or converter; a whine that follows road speed in gear points to the gear train. Our Ford noise diagnosis guide walks through those tests. When the unit is apart, spin each pinion, check pinion end play and look for heat discoloration and cracked welds on the carrier.
Fits the 4R44E from 1995 to 2001, the years it was used in the Ranger and Mazda B-Series with the 2.3L and 3.0L engines. The heavier 4R55E for the 4.0L uses a different part listing. Ford changed many internal parts during these years, so compare your old carrier for pinion count, spline count and reluctor tooth count before you install, or send us your year and VIN. The 4R44E shares a family with the 5R55, and related parts are on our 5R55 family parts page.

It is the overdrive planetary carrier assembly at the front of the gear train. It has solid pinion pins and comes with the electric pick-up reluctor that a speed sensor reads.
Only if the carrier is the cause. Loss of 4th is often caused by the overdrive band, servo or valve body leaks. Check line pressure and the band before you replace the gearset.
Inspect the overdrive sun gear, ring gear and one-way clutch, replace the thrust washers and bearings, and install a master rebuild kit if there is debris in the pan. Flush the cooler before you put the transmission back in.
Clear the codes and let the computer relearn shift timing with a few normal drive cycles. Check that the speed sensors read correctly on a scan tool during the road test.
