4R70W Solenoid Kit, remanufactured and ready to install. Fits the 4R70W. Ships fast from the USA.
If your F-150, Expedition, Crown Victoria or Mustang with the 4R70W is starting in second, refusing overdrive, banging into Drive or setting P0750, P0755 or P1747, this is the full electrical service set in one box. The listing photo shows five pieces, each with its Ford number printed beside it: the shift solenoid pack (F7AZ-7G484-AA), the electronic pressure control solenoid (F6AZ-7G383AA), the torque converter clutch solenoid (F5AZ-7G136A), a pan filter (F6AZ-7A098A) and a cork pan gasket (F2VY-7A191A). The kit is remanufactured and is listed against the F-150 application.
The 4R70W picks its four forward gears with just two on/off solenoids that live together in the pack. Per the Sonnax and ATRA charts, 1st is SS1/A on, 2nd is both off, 3rd is SS2/B on and 4th is both on. That is why a dead 12-volt feed leaves the truck in 2nd with a good Reverse: Reverse is set by the manual valve, not the solenoids. The EPC solenoid is a variable force part that meters line pressure, and Ford built it so zero current means maximum pressure. The TCC solenoid applies the converter clutch once the computer sees cruise conditions. Replacing all three at once makes sense when the unit has high mileage and you are already dropping the pan.
Read which gear the truck is stuck in first, because the chart tells you which solenoid failed and in which direction. Then unplug the case connector and measure each circuit: Sonnax gives 20-30 ohms for each shift solenoid, 10-16 ohms for TCC and 2-5 ohms for EPC. A low EPC reading is normal, not a short. If every circuit reads open from the shared power pin, suspect one bad terminal before four bad solenoids. Our 4R70W shift solenoid testing guide has the full pin chart, and the EPC solenoid guide covers the line pressure gauge test and the worn pressure regulator bore that a new EPC will not cure.
This listing does not carry a year range, so treat the printed Ford numbers as the fitment check. Sonnax shows three case connector generations across this family (1997 and earlier, 1998-2008, and 2009 and later), and solenoid styles changed with them. Pull your old pack, EPC and TCC and compare the numbers and connector shapes to the photo, and hold your old filter beside the one shown, since pans and filter depths vary between 2WD, 4WD and aftermarket deep pans. If you would rather we check it, send your year, model and VIN before ordering. Kits listed by year, such as the 1998-2004 shift solenoid and filter kit and the 2005-2008 solenoid kit, are on the 4R70W parts collection page.
Drain, drop the pan and pull the filter. Unplug each solenoid, remove the retainers and lift the parts out, keeping track of which bolt holds what. Lube every new O-ring with ATF and push each solenoid straight into its bore; TeckPak warns that a rolled EPC O-ring causes low line pressure. Inspect the internal harness or lead frame and the case connector pins while you are in there, because Transmission Digest documented a case where pushed-back connector terminals caused solenoid codes after a fresh rebuild. If the wiring is brittle, an internal wiring harness is cheap insurance on early units. Install the new filter and gasket, refill with MERCON V as Ford specifies, clear codes, reset adaptive memory and road test through all four gears.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The listing photo shows a shift solenoid pack, an EPC solenoid, a TCC solenoid, a transmission filter and a cork pan gasket, each labeled with its Ford part number.
No year range is listed, so match the Ford numbers in the photo (F7AZ-7G484-AA, F6AZ-7G383AA, F5AZ-7G136A) to the parts on your valve body, or send us your year and VIN and we will check it.
Possibly. Both shift solenoids off gives 2nd gear, so a failed solenoid, a lost 12-volt feed or a bad case connector terminal can all do it. Measure the circuits at the case connector before replacing parts.
MERCON V. Ford's fluid chart lists it for the 4R70W and 4R75W and advises against supplemental additives.
Clear all codes, reset the adaptive memory with a scan tool or by disconnecting the battery, check the fluid level hot, and road test at light and moderate throttle so the computer relearns shift timing.
