Remco overhaul kit for 1997-2003 Ford 4R70W and 4R75W: friction pack, overdrive band, pump bushing, 2WD filter and gasket set. Steels not included.
The 1997-2003 4R70W is the transmission behind the 4.6-liter and 5.4-liter in the F-150 and Expedition of those years, and in the Crown Victoria, Grand Marquis, Town Car and Mustang. When one of them starts slipping on the 2-3 shift, sits in neutral for a moment before Drive engages, or drops into a slip when it shifts to overdrive, an overhaul is the usual answer. This Remco kit (part number RK4R70W) packs the parts that wear in that kind of failure: the friction clutch pack, a flex overdrive band, the front pump bushing, a 2WD filter and the full overhaul gasket and seal set. Steel plates are not included, which keeps the price down if yours are still flat and clean.
Each forward gear in the 4R70W comes from clutch packs and bands clamping parts of the planetary set. The overdrive band wraps a drum and holds it for second and fourth gear, and it is one of the parts that cooks first when line pressure drops or the servo loses apply. The pump bushing supports the converter hub at the front of the unit; once it wears, the pump loses pressure and converter charge oil leaks away. This kit addresses both, along with every friction and seal, which covers the most common reasons a 1997-2003 unit comes out of the truck.
Scan for codes and test the solenoids and EPC circuit before buying a kit, since electrical faults can mimic worn clutches. On 2001-2003 units, look at the valve body too. Transmission Digest and Sonnax report that Ford deleted the two-bolt stiffener plate in 2001, and the resulting cross leak between the forward and direct circuits is a known cause of burned clutches. Sonnax ties burned bands and a 4-3-neutral complaint to overdrive servo regulator wear. If you rebuild the clutches without fixing that leak, the new frictions will burn again. Our 4R70W Expedition shift problems guide and the Crown Victoria common problems guide walk through both checks.
This kit is for 1997-2003 Ford 4R70W and 4R75W transmissions. Year coverage differs by component: the gasket set is 1997-2003, the friction pack is 1994-up, and the filter is the 1996-up 2WD style. A 4WD truck may need a different filter, so check yours against the one in the kit before you put the pan back on. Confirm the case tag reads 4R70W or 4R75W, and send us your year and VIN if you are unsure. 2004 and later units are a different design and need the 2004-up complete rebuild kit. Every 4R70W part we stock is on the 4R70W collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It includes frictions, an overdrive band, a pump bushing, a 2WD filter and the gasket and seal set. Inspect your steels and buy them separately if they are heat-damaged.
The clutches and gaskets will fit a 1997-2003 4R70W, but the filter in the kit is the 2WD style. Compare it with your old filter and use a 4WD filter if the pickup does not match.
It replaces the burned frictions that cause the flare. On 2001-2003 units, also fix the valve body cross leak or the new direct clutch can burn again.
No. Ford redesigned the transmission for the 2004 F-150. Use the 2004-up complete rebuild kit instead.
The 1997-2003 4R70W uses MERCON V. Soak the frictions in it before assembly and check the level hot with the engine running in Park.
