4R70W Banner Rebuild Kit 1996-2003, new and ready to install. Fits the 4R70W. Ships fast from the USA.
From the mid-1990s through 2003 the 4R70W sat behind Ford's 4.2L V6 and 4.6L and 5.4L V8s in the F-150, the 4.6L Expedition, the Mustang, and the Crown Victoria, Grand Marquis and Town Car. Most of those vehicles now have well over 150,000 miles, and plenty have towed or worked fleet duty. If yours slips going into drive, flares between gears, has lost the direct clutch, or shows dark, burnt-smelling fluid, this new banner rebuild kit gives you the frictions, overhaul seals and gaskets, and the filter to put a 1996-2003 unit back in service.
The 4R70W grew out of the AOD and AODE. It uses a Ravigneaux gearset with forward, direct, intermediate and reverse clutches plus overdrive and reverse bands, all applied by hydraulic pressure from the valve body under electronic control. The forward clutch is fed through the pump and the direct clutch through the output shaft. When the piston seals or sealing rings in those circuits leak, the pack slips and burns. The banner kit replaces the soft parts that wear in every overhaul: frictions, seals, sealing rings, gaskets and the filter. Steels, bushings, drums and gear sets are not included and need inspection.
Scan for codes first. A full set of solenoid codes at once usually means the unit lost its power feed, not that the internals failed. Then do a line pressure check; a worn pressure regulator bore can make a healthy unit slip. Our 4R70W Expedition common problems guide lays out that order, including the cross leak below.
Through the 2000 model year a two-bolt stiffener plate clamped the separator plate under the 2-3 accumulator. Sonnax's Gregg Nader documented that Ford deleted it for 2001. Without the clamp, forward clutch oil bows the separator plate and leaks into the direct circuit, so the direct clutch drags in first and second. A new direct pack on an unmodified 2001-2003 valve body can burn again. Clamp the plate again with a retainer plate such as Sonnax 76507F-01K before the valve body goes back on.
This kit is listed for 1996-2003 4R70W transmissions. Inside that span there are speed sensor connector changes and the 2001 valve body update, but the soft parts are shared across the listed years. The bigger break is 2004, when the ring gear, output speed sensor and sun shell changed, so 2004-up units need a different kit. Read the ID tag on the case, not just the model year, or send us your year and VIN. On a 1997-2002 Expedition, confirm you have the 4R70W and not the larger 4R100 behind the 5.4L. See every part for this family on the 4R70W/4R75W collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. 2004 brought a new ring gear, output speed sensor and non-magnetic sun shell, and the parts do not interchange. Use a 2004-up kit for those units.
A banner kit gives you the frictions, the overhaul gasket and seal set, and the filter. It does not include steels, bushings or bands, which a master kit or separate parts would cover.
Ford removed the stiffener plate under the 2-3 accumulator in 2001, which lets forward oil cross leak into the direct circuit. Install a retainer plate such as Sonnax 76507F-01K during the rebuild.
MERCON V. Capacity varies by vehicle and cooler; Ford lists about 13.9 quarts dry fill for the 2003 Crown Victoria. Fill by the dipstick with the fluid hot rather than by a number.
Yes, when the vehicle has a 1996-2003 4R70W. The soft parts are shared across these applications. Check the case tag to confirm the transmission before ordering.
