4R70W Banner Rebuild Kit 2004, new and ready to install. Fits the 4R70W. Ships fast from the USA.
Owners of a 2004 F-150 with the 4.6-liter V8, a 2004 Mustang, a Crown Victoria, Grand Marquis or Town Car usually land here after the transmission starts slipping on the 2-3 shift, engages Drive with a delay, or leaves burnt-smelling fluid on the dipstick. This is a Raybestos banner kit for the 2004 4R70W: the photo shows the full overhaul gasket and seal set with the Raybestos friction pack and sealing rings, the soft parts a standard rebuild calls for.
The 4R70W shifts by clamping its forward, direct, reverse and intermediate clutch packs and applying the overdrive and low-reverse bands, all with oil pressure that has to be sealed every step of the way. Friction plates wear thin and glaze from heat, and the piston lip seals and Teflon rings that hold apply pressure harden with age. When both happen the unit slips, slipping makes more heat, and the decline speeds up. The banner kit renews the friction lining and the sealing together, so each circuit applies with full force again.
2004 is a different animal from the earlier units. Transmission Digest's November 2004 summary explains that Ford introduced a revised rear-drive unit for the new 2004 F-150 and E-150, tagged 4R70E behind the 4.6-liter engine and 4R75E behind the 5.4-liter. It added a turbine shaft speed sensor in the center of the case, a riveted sun shell made of a less magnetic material, and a rear ring gear with extended parking lugs that trigger the output speed sensor. None of those parts interchange with the older 4R70W.
Pull trouble codes before you tear anything down. A TSS or OSS fault on a 2004 can produce harsh or erratic shifts that feel like worn clutches, and a stuck solenoid can mimic slip. Check the fluid hot, then pull the pan. Heavy friction material on the magnet confirms worn packs. A clean magnet with poor shifts sends you to the valve body, where the post-2001 forward-to-direct cross leak is a known cause of burned clutches. Our 4R70W F-150 common problems guide walks through that diagnosis order, and the Crown Victoria common problems guide covers the Panther cars.
This kit is listed for 2004 4R70W transmissions, including the 4R70E name Ford used in the redesigned 2004 F-150 with the 4.6-liter engine. Ford ran older and newer designs side by side that year, so check the transmission code on the door tag and the ID tag on the case, compare a friction from your old packs with the kit, or send us your year and VIN to confirm. If your 2004 truck has the 5.4-liter, it carries the 4R75E and the 2004 4R75W banner kit is the right listing. Every other version is on the 4R70W collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, if the truck has the 4.6-liter V8. Ford used the 4R70E name on the revised unit in the 2004 F-150 and E-150 with the 4.6-liter. The 5.4-liter got the 4R75E, which has its own listing. Send us your VIN if you are unsure.
The kit is listed for 2004 4R70W units, which includes those cars. Read the ID tag on the case and compare an old friction with the kit before assembly, because Ford ran older and newer designs side by side that year.
Steels, bushings, bands and the filter are not shown in the kit photo. Measure the steels and bushings at teardown and buy only the ones that are worn.
MERCON V. Ford specifies it for 4R70W units and warns against using it where MERCON LV, ULV, SP or Type F is called for.
On 2000 and later units the intermediate clutch can rattle in the case until the 1-2 shift if the anti-rattle clip is missing. Reinstall the clip during assembly.
