4R55E Banner Rebuild Kit, new and ready to install. Fits the 4R55E. Ships fast from the USA.
For a 4.0L Ford Ranger, Explorer or Mazda B4000 whose four- or five-speed automatic has started slipping, flaring or engaging slowly, the frictions and seals are usually the first things to go. This banner kit covers both at a lower price than a full master kit. It is cataloged for 1997-up 4R44E, 4R55E and 5R55E transmissions and comes with 16 pieces: 15 friction plates for all three clutch packs and one overhaul gasket and seal kit.
All 15 frictions are 0.069 in. thick with spiral grooves and are labeled with A4LD part names, because the 4R55E grew directly out of the A4LD. Not included: steel plates, filter, bands and the pump bushing.
Ford gave the A4LD full electronic controls for 1995 and split it into the 4R44E for four-cylinder and 3.0L trucks and the 4R55E for the 4.0L. Wikipedia says the two are basically the same design, with the 4R55E using stronger parts and a 550 lb-ft rating after converter multiplication. The direct, forward and overdrive clutches take turns carrying that torque through the gear changes. Spiral-grooved frictions move fluid across the plate, which helps cooling, but once the facing glazes the clutch slips on every apply. A banner kit renews the lining in all three packs and reseals every piston, so the clutches lock up firmly again.
Not every 4R55E slip is a worn clutch. A leaking EPC circuit, a weak solenoid or a worn coast clutch valve can produce the same flares on clean fluid. Run the pressure test in our line pressure testing guide, and if pressure is low, try a 4R55E EPC solenoid before pulling the unit. Our slipping diagnosis guide covers the rest of the checks.
This kit is cataloged for 1997-up 4R44E, 4R55E and 5R55E rebuilds. Wikipedia notes the four-speed 4R55E was replaced by the 5R55E during the 1997 model year, so most 1997-up 4.0L trucks are five-speeds, and the five-speed shares this case and clutch packs. The kit catalog also names some 1995-1996 Explorer, Ranger and Aerostar trucks; those earlier units differ, so check them against our 1995-1996 4R55E banner kit first. This is a different transmission from the 5R55W and 5R55S in 2002-up Explorers and Mustangs, and the kit does not fit those. Check the code on the door label and the case tag before ordering, or send us your year and VIN. More parts for the family are on the 5R55 transmission parts page.

Fifteen: 6 direct, 6 forward and 3 overdrive, all 0.069 in. thick with spiral grooves, plus one overhaul gasket and seal kit.
No. Steel plates, the filter, bands and the pump bushing are not in this kit. Inspect yours and order what is worn.
Yes. It is cataloged for 1997-up 4R44E, 4R55E and 5R55E units, which share the case and clutch packs. It does not fit the 5R55W or 5R55S.
The kit is cataloged for 1997 and later. For a 1995-1996 truck, check our 1995-1996 4R55E banner kit, or send the VIN and we will confirm.
The 4R44E and 4R55E are electronic versions of the A4LD and use the same friction sizes in these packs, so they are cataloged under the A4LD names.
