4R44E Master Rebuild Kit 1997, new and ready to install. Fits the 4R44E. Ships fast from the USA.
The 4R44E is the four-speed automatic behind the 2.3L four-cylinder and 3.0L V6 in late-1990s Ford Ranger and Mazda B-Series pickups. Once one of these slips on the 1-2 or 2-3 shift, takes its time finding reverse, or shows black fluid with band lining on the magnet, it is past the point of a fluid change. This new master rebuild kit is cataloged for the 1997-up 4R44E in two-wheel-drive trucks and supplies every wear part for a full overhaul in a single order.
Ford built the 4R44E for 1995 by putting full electronic control on the old A4LD, and the Ranger Station rates it at 440 lb-ft after converter multiplication, a lighter-duty sibling of the 4.0L 4R55E. Ratios are 2.47 first, 1.47 second, 1.00 third and 0.75 overdrive. Three bands do much of the holding in this design, applied by servos and fed by line pressure that the electronic pressure control (EPC) solenoid sets. A four-cylinder Ranger that is worked hard or towed with runs that pressure high for long stretches, and the bands glaze and shed lining before the clutches give up. Because band debris circulates through every circuit, the right repair is new frictions, steels, bands and seals throughout, which is exactly what this box covers.
Several of those symptoms can also come from the valve body. Sonnax traces delayed reverse, 1-2 and 2-3 flares and even broken bands and blown servo seals to wear and leakage in the EPC circuit, and loss of fourth or engine braking to coast clutch valve leakage. Its vacuum test guide also links code P0741 and converter clutch slip to worn TCC valves. So pull the pan before you order: clean fluid and a clean magnet point to a hydraulic or solenoid problem, while lining on the magnet and a burnt smell mean worn bands and clutches. Our harsh or delayed shift walkthrough for this family and the slipping diagnosis guide lay out the checks.
The listing year is 1997, and the kit is cataloged for 1997-up 4R44E, 4R55E and 5R55E units in 2x4 trucks. The Ranger Station lists the 4R44E in 1995-2000 Rangers with the four-cylinder or 3.0L. This box is the two-wheel-drive version: the filter and extension housing bushing suit the 2WD case, so a 4x4 will not use them. A 1995 or 1996 4R44E is an earlier design; use our 1995-1996 4R44E kit for those. Read the transmission code on the door label and the tag on the case, and send your year, drivetrain and VIN if you want us to confirm. The rest of this transmission family is on our 5R55 and 4R44E parts page.

Not as supplied. It is the 2x4 version, with the 2WD filter and extension housing bushing. Four-wheel-drive trucks need the 4x4 filter and rear bushing, so tell us your drivetrain before ordering.
Yes. Along with the Borg-Warner frictions it has steel plates and all three bands: intermediate, overdrive and reverse. It also includes the filter, pump bushing and extension housing bushing.
This kit is cataloged for 1997-up units. For a 1995-1996 transmission use the earlier 4R44E kit, or send us your VIN and we will match it.
No. If the old unit failed with heavy debris, the converter should be replaced or rebuilt, because it holds contaminated fluid and lining that will reach the new clutches.
Only if worn bands or clutches are the cause. Sonnax documents delayed reverse from EPC circuit leakage and worn reverse modulator valves, so check the valve body during the overhaul.
The kit is listed for the 1997-up 4R44E, 4R55E and 5R55E in 2WD trucks. Confirm your exact code on the door label or case tag first.
