4R70W Banner Rebuild Kit, new and ready to install. Fits the 4R70W. Ships fast from the USA.
If your Ford F-150, Expedition, Crown Victoria, Grand Marquis, Town Car or Mustang with the 4R70W has started flaring between gears, taking a second or two to pick up Drive on a cold morning, or turning its fluid dark and smoky, the clutch packs and seals are usually where the money goes. This listing is a Toledo Trans-Kit banner rebuild kit for the 4R70W, packaged by Seal Aftermarket Products. It is the budget path through an overhaul: new friction material and the sealing parts, without paying for steels and hard parts you may be able to reuse.
The 4R70W is a four-speed rear-drive automatic that builds every gear by holding or driving parts of a Ravigneaux planetary set. Clutch packs (forward, direct, reverse, coast and intermediate) and two bands do that work, and each one is applied by fluid pressure pushing a piston. Two things wear out: the paper lining on the frictions, and the rubber and Teflon seals that keep apply pressure from leaking away. A banner kit bundles fresh frictions with the overhaul gasket and seal set and a filter, so both halves of the problem get renewed in one teardown. What it leaves out is everything metal: steel plates, bushings, drums and planetary parts are reused unless you find damage.
Scan for codes first. Shift solenoid, EPC and TCC solenoid faults are some of the most common 4R70W complaints and can feel like a worn transmission when the clutches are actually fine. Next, drop the pan. A thin film of grey paste on the magnet is normal wear; clumps of friction material, flakes of band lining or brass chips mean the unit needs to come out. Sonnax's vacuum test guide is useful if the clutches look acceptable but shifts are still wrong, since a worn solenoid regulator, overdrive servo regulator or pressure regulator bore can produce slip on its own. Our 4R70W F-150 shift problems guide covers that diagnostic order, and the Expedition common problems guide lists the failures that show up on heavier trucks.
This kit is listed for the 4R70W without a specific year range, and the 4R70W changed several times between 1993 and 2008. Transmission Digest notes that Ford redesigned the unit for the 2004 F-150 and E-150 with a turbine speed sensor and new sun shell and ring gear, and 2001 units dropped the valve body stiffener plate. Seal and friction counts can shift with those revisions. Before ordering, check the transmission code on the door jamb tag and the ID tag on the case, or send us your year and VIN and we will confirm the kit matches. If you already know your year, the 1996-2003 banner kit and the 2004 banner kit are year-specific options. Every 4R70W part we carry is on the 4R70W collection page.
If your teardown shows burned steels as well as frictions, a kit that includes both, such as the 4R70W master rebuild kit with frictions and steels, is the better buy.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
A banner kit gives you the overhaul gaskets and seals, friction plates and a filter. A master kit adds steel plates and usually bands and a bushing set. If your steels are flat and not heat-marked, a banner kit is the lower-cost way to rebuild.
The listing covers the 4R70W without a specific year range. Because Ford revised the unit in 2001 and again in 2004, send us your year and VIN or the case tag number and we will confirm fitment before it ships.
No. Inspect your steels and bushings during teardown. If the steels are blued, scored or warped, order a kit that includes steels or buy them separately before reassembly.
The 4R70W takes MERCON V. Soak the new frictions in it before assembly and check the level hot with the engine idling in Park.
On a high-mileage unit it is a good idea. Shift solenoid, EPC and TCC solenoid faults are common on the 4R70W, and the solenoid pack is easy to replace while the pan and valve body are already off.
