4R75W Governor Pressure Solenoid 2005-2008, new and ready to install. Fits the 4R75W. Ships fast from the USA.
Searching for a 4R75W governor pressure solenoid usually means a late Ford truck or police car that has started shifting badly, and the parts listings are confusing. The 4R75W never had a governor. Line pressure and shift timing are controlled electronically, and that is what this package replaces: a dual shift solenoid pack, an EPC pressure solenoid and a torque converter clutch solenoid, with a new filter and a Duraprene gasket for the 14-bolt pan used on 2005-2008 units. It is the set to reach for when a 4R75W behind a 4.6L or 5.4L starts flaring, slamming, hunting for gears or refusing to lock up.
The 4R75W is the heavier-duty member of the 4R70W family, built for more torque and weight, but its electronic control works the same way. Two on/off shift solenoids in a single pack give the valve body its gear commands. The EPC solenoid is the one that matters most in a heavy truck or a fleet car: it continuously sets line pressure, and because the computer raises pressure with throttle and load, a weak EPC shows up first as clutches and bands sliding when the vehicle is working hard. The TCC solenoid controls converter lockup, which cuts heat and slip at highway speed. In 1998-2008 units the solenoids connect through a rigid molded lead frame bolted inside the case.
Before buying, check fluid level and condition, pull codes, and measure the solenoid circuits at the case connector. Electrical readings in range with pressure complaints point to the hydraulics; Transmission Digest has shown how a worn pressure regulator bore bleeds EPC oil back to the pump inlet so line pressure never rises, no matter how good the solenoid is. A gauge on the line pressure tap during a stall or road test separates the two. Our 4R70W and 4R75W F-150 common problems guide and the Expedition common problems guide lay out the known weak points by vehicle.
The listing covers 4R75W transmissions from 2005 through 2008 with the 14-bolt pan. Earlier 1993-1997 units in this family used a white soft-wired case connector and different solenoids, and ATRA warns they do not interchange with the black 1998-on hard harness design. For 2009 Ford replaced the lead frame with a new soft harness and new solenoids, and ATSG states none of those parts retrofit to older units. Confirm your pan bolt count and connector before ordering, and if your truck or car was built near a model-year changeover, send us the year and VIN so we can check it. More parts for this family are on our 4R70W and 4R75W parts page.
If testing shows the valve body itself is worn, the 2005-2008 valve body with filter and gasket is the next step up. For a truck that is coming apart anyway, the 4R75W master rebuild kit supplies the frictions and seals.

No. The 4R75W is electronically controlled with no governor. This item is the solenoid set that does that job: shift solenoid pack, EPC solenoid and TCC solenoid, plus filter and pan gasket.
It is listed for 2005-2008 units with the 14-bolt pan. 1993-1997 units and 2009-later units use different connectors and solenoids, so they are not a match.
Only if the EPC solenoid or its circuit is the cause. Worn pressure regulator bores and worn clutches also cause slipping under load, so check line pressure with a gauge before you buy.
MERCON V for 2005-2008 units. Check the level with the engine running and the fluid at operating temperature.
Clear the codes and drive the vehicle through every gear and converter lockup so the computer adapts to the new parts. No special programming is needed for the solenoids.
