Master overhaul kit for the Ford 4R70W, 4R75W and 4R75E with gaskets, seals, O-rings, frictions and steels to rebuild a 1997-2003 unit.
If the tag on your Ford four-speed reads 4R70W, 4R75W or 4R75E and the truck or car is a 1997-2003, this is the master kit built for that case. It is the parts load for owners of an F-150, Crown Victoria, Mustang, Explorer V8 or E-series van who are past the point of a fluid change: the transmission slips on the 2-3, takes a long time to pick up Drive, or the pan came off full of black clutch material. The kit carries manufacturer part number ING-GN02979 and includes the gaskets, lip seals, O-rings, sealing rings, friction plates and steel plates, so the clutch packs and the seals behind them are renewed in the same teardown.
The 4R70W is a four-speed rear-wheel-drive overdrive automatic from the AOD family. Each gear is made by applying a combination of clutch packs and bands with hydraulic pistons, and the computer times those applies through the shift solenoids and EPC. Two things wear out together: the friction material on the plates, and the rubber and sealing rings that hold pressure behind each piston. When a piston seal or a pump stator sealing ring leaks, the pack it feeds gets less pressure, slips, overheats and burns. A master kit replaces both halves of that problem. Note what it does not include: no bands, bushings, filter or hard parts. Plan to inspect and source those separately.
Pull codes and check the solenoid power feed first. On these transmissions a whole set of solenoid codes at once usually means a lost power feed, not a dead transmission, and our 4R70W Explorer common problems guide walks through the shared fuse and harness checks. Then check fluid hot and look at the pan. If the shift complaint is a soft or late shift with clean fluid, a pressure fault in the valve body is more likely than worn clutches, and the F-150 shift problems guide covers how to tell the two apart. Sonnax's vacuum test guide for this family is also useful for isolating worn valve body bores before teardown.
The listing covers 1997-2003 Ford applications with the 4R70W family, including Crown Victoria, Econoline, Excursion, Explorer, F-150 and Mustang. Be careful with two of those. In the Explorer, the 4R70W sat only behind the 5.0L V8; V6 trucks used a completely different transmission. In the heavier Econoline and Excursion builds, Ford often used a larger unit, so go by the tag on the case, not the vehicle badge. This kit is not for 2004-up units: ATRA documents that the ring gear and output speed sensor changed for 2004 with no interchange, and those cases take the 2004 4R70W master kit. If you are unsure, send us your year and VIN, or browse every part for this transmission on the 4R70W collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It includes gaskets, seals, O-rings, sealing rings, frictions and steels. Bands, bushings, the filter and hard parts are separate, so inspect those during teardown and order what is worn.
It is listed for the 4R70W, 4R75W and 4R75E in 1997-2003 applications. Confirm the year on your tag; 2004 and later cases changed and need a 2004-up kit.
A delayed Drive engagement on a 4R70W is commonly a leaking forward clutch piston seal or worn sealing rings. Check fluid level first; if it is correct, the seals in this kit are the repair.
No. Only the 5.0L V8 Explorers used the 4R70W. V6 Explorers have a different transmission, so check the transmission code on the door tag.
MERCON V. Ford's 2003 Crown Victoria owner guide lists about 13.9 quarts dry for that car; other vehicles and cooler setups vary, so finish the fill on the dipstick hot.
