Replaces the shift, EPC, and TCC solenoids plus the filter and pan gasket on 2005-2008 Ford 4R70W and 4R75W transmissions with the 14-bolt pan.
This is a one-box electrical service for the late Ford 4R70W and 4R75W with the 14-bolt oil pan, built 2005 through 2008. The listing names F-150 and E-Series van applications of that era. If your truck or van is shifting harshly, hanging in a gear, refusing to lock the converter or storing codes in the P0750, P0755 or P0743 range, the kit replaces the shift solenoids, the EPC solenoid and the TCC solenoid together, and gives you a new filter and pan gasket so the pan only comes off once.
Think of the solenoids as the computer's hands inside the valve body. Two shift solenoids decide the gear by their on/off pattern - Sonnax's chart shows both off for 2nd and both on for 4th, with 1st and 3rd using opposite combinations. The EPC is a variable force solenoid that trims line pressure for every shift and engagement; Ford's patent on this control describes a 0-1 amp signal producing a 0-6 bar output, with the highest pressure at zero current. The TCC solenoid locks the converter so the engine is not slipping at highway speed. On a work truck or a loaded van these parts see a lot of heat cycles, and they tend to wear out as a set.
Pull codes, then go to the case connector before you drop the pan. The 1998-2008 units use their own connector style, and Sonnax publishes the pin map and resistance specs: 20-30 ohms per shift solenoid, 10-16 ohms TCC and 2-5 ohms EPC. A circuit that reads open at the connector but good at the solenoid is a harness or terminal fault. If the electrical numbers are right and shifts are still soft under load, put a gauge on line pressure, because valve body bore wear can bleed off EPC oil. Our shift solenoid symptoms and testing guide and the Expedition shift problems guide cover both checks in more detail.
Listed for the Ford 4R70W and 4R75W with the 14-bolt pan, 2005-2008. Later Ford paperwork also calls these units 4R70E and 4R75E, and both naming styles describe the same family. Count your pan bolts first: the earlier transmissions use a different pan and filter, and the filter in this box is sized for the 14-bolt pan. The kit cross-references service numbers 76919, 76420, 46118, 76923 and 76921 and Ford numbers including F6AZ-7G383AA and F7AZ-7G484-AA, so you can compare against what is on your valve body. If you are unsure, send your year and VIN. Every other version for this family is on the 4R70W and 4R75W collection page.
Drain the fluid and drop the pan on a lift or stands with a large catch pan. Remove the filter, unplug the solenoids and unbolt them from the valve body, then fit the new ones with fresh O-rings lubricated in clean ATF. Look over the internal harness while it is exposed; if the insulation is brittle or the connector is damaged, the solenoid kit with wire harness is the better buy. Install the new filter and gasket, torque the pan bolts evenly, and refill with six-plus quarts of MERCON V, the fluid Ford's chart specifies. Check the level hot. If the transmission has high miles and the bands are suspect, a Kevlar overdrive and reverse band set belongs in the same rebuild.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2005-2008 Ford 4R70W and 4R75W transmissions with the 14-bolt oil pan, including F-150 and E-Series applications of that period. Confirm the pan bolt count and connector, or send your year and VIN.
The shift solenoids, the EPC solenoid, the TCC solenoid, a transmission filter and a pan gasket. Fluid is not included.
Plan on six or more quarts of MERCON V for a pan-drop refill. Check the level with the transmission at operating temperature.
The pan and valve body access are the labor. The solenoids share the same heat history, so replacing the set while you are in there avoids a second pan drop when the next one fails. Test the harness first so you know the solenoids are the cause.
Not as a complete match. Earlier units use a different pan and filter, and Sonnax shows a different case connector before 1998. Look at the 1998-2004 and 1996-1997 kits on our 4R70W page.
