4R70W Shift Kit 2005-2008, remanufactured and ready to install. Fits the 4R70W. Ships fast from the USA.
The title on this listing says shift kit, but what you get is a solenoid service set for the late 4R70W and 4R75W: a dual shift solenoid pack, an EPC (electronic pressure control) solenoid and a TCC lockup solenoid, all remanufactured and tested, plus a new filter and a new pan gasket for the 14-bolt pan. It is aimed at 2005-2008 F-150s and the Crown Victoria, Grand Marquis and Town Car of those years when the transmission shifts erratically, sits in 2nd, will not lock the converter, or sets solenoid codes. It contains no valve body springs or valves.
The computer picks the gear by switching the two coils in the shift pack on and off; the pattern of the two selects 1st through 4th. With both off, the unit falls back to a fixed gear, which is why an electrical fault often feels like the truck is stuck in 2nd. The EPC solenoid is a variable force part that sets line pressure for every shift, and on these Fords more current means less pressure. The TCC solenoid applies and releases the converter clutch. All three bolt to the valve body and plug into the internal lead frame, so they can be replaced with the pan off.
Measure the solenoids through the case connector before you drop the pan; an open or shorted reading confirms a part, while correct readings with codes point at wiring. Transmission Digest has documented solenoid codes and higher-gear starts caused by an aftermarket case connector with pushed-back terminals, so look there too. Our 4R70W shift solenoid testing guide lists the steps, and if the truck will not reach 4th, read why a 4R70W will not shift into overdrive first.
The listing fits Ford 4R70W and 4R75W 14-bolt pan models from 2005 through 2008. That window sits inside the molded lead frame era Ford introduced in 1998. For 2009 the 4R75E went back to a soft internal wire harness with all new design solenoids, and ATSG notes none of those parts retrofit to earlier units, so a 2009-up truck needs different parts. 1993-1997 units with the white connector also use different solenoids. Match your pan, connector and year, or send us the year and VIN. More parts for this family are on our 4R70W collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Despite the title, it is a solenoid service set: dual shift solenoid pack, EPC solenoid and TCC solenoid, remanufactured, with a new filter and pan gasket. It does not change valve body calibration.
No. Ford changed the 2009-up 4R75E to a soft internal harness with all new solenoids, and those parts do not interchange with 2005-2008 units.
The solenoids are remanufactured and tested. The filter and pan gasket are new.
No. The solenoids, filter and gasket are all serviced with the pan dropped.
Refill with MERCON V. A pan drop only replaces part of the fluid, so add a few quarts, start the engine, and top up to the hot full mark in Park.
Clear the codes and drive normally through all gears; adaptive shift feel settles over the next several drives.
