5R44E Planetary 1997-2011, new and ready to install. Fits the 5R44E. Ships fast from the USA.
Read this first: although this item is filed under planetary, it is not a gearset. What ships is a complete super master rebuild kit for the 5R44E, 5R55E and 4R44E, the small Ford rear-drive automatics used through 1997-2011 in Ford, Lincoln, Mazda and Mercury applications. If your rebuild needs a planetary carrier, see the 5R44E planetary listing. If you are rebuilding a slipping, flaring or burnt unit and want one box with the wear parts, keep reading.
Not included: the reverse (rear) band and the torque converter. All components are new.
Sonnax explains that the 4R44E arrived in 1995 behind the 2.3L and 3.0L, the 4R55E in 1996 with the 4.0L, and that in 1997 Ford turned both into five-speeds by applying the front servo to get an overdriven first and fifth. That means the overdrive and intermediate bands work harder in a 5R44E or 5R55E than they did in the four-speed, and worn bands are a standard failure in this family. Having both new bands in the kit, along with fresh frictions and steels, covers the parts that usually cause a rebuild in the first place.
Sonnax traces several of these to the EPC circuit: leakage and a sticking EPC and engagement control valve can cause delayed reverse, flares and harsh shifts, and EPC problems can also break bands and blow out servo piston seals.
Rule out the valve body and solenoids before you commit to a teardown. A unit that slips because of a leaking EPC circuit will slip again on new frictions. Start with a line pressure test, scan for codes, and follow our 5R55 harsh or delayed shift walkthrough. The rebuild cost guide helps you weigh a kit rebuild against a replacement unit.
Listed for 1997-2011 5R44E, 5R55E and 4R44E transmissions in Ford, Lincoln, Mazda and Mercury applications that use the 2WD (4x2) filter. 4x4 trucks use a different filter, so if your unit is four-wheel drive you will need to source that filter separately. Hard parts and valve bodies changed many times after 1995, so confirm your transmission model on the door tag and compare the clutch plates against your old ones, or send us your year and VIN. More parts for this family are on the 5R55 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Despite the listing name, this is a super master rebuild kit with seals, gaskets, frictions, steels, two bands, two bushings and a filter. Planetary carriers are sold separately.
No. The kit has the overdrive and intermediate bands only. Inspect the reverse band and replace it separately if the lining is worn.
The internal parts are listed for the 5R44E, 5R55E and 4R44E, but the filter in this kit is the 2WD (4x2) style. A 4x4 needs a different filter.
Current Mercon V. Flush the cooler and lines completely, since early Mercon V fill was linked to solenoid problems in this family.
A converter is not included. If the old unit failed with heavy debris, have the converter replaced or rebuilt, since debris trapped inside will contaminate the new parts.
