Many Powerstroke owners spend thousands of dollars 'bulletproofing' their engines. How about showing the transmission a little love with some Ford 5r110w transmission plugs?

The 5R110W Torqshift transmission came equipped with dummy pressure switches in the valve body that were never used or monitored by the computer in any production vehicle. These plastic / rubber switches are prone to failing from heat and leaking or blowing out of the valve body. This causes a drop in transmission line pressure, missing up-shifts, slipping clutches, and ultimately transmission failure.

Trucks that have performance programmers usually have higher shift pressures - and will be more likely to experience pressure switch failure.


A simple 5r110w transmission upgrade is as easy as replacing the unused pressure switches with machined aluminum o-rings plugs that will never fail! Once the transmission pan is removed it takes only minutes to install our Ford 5r110w transmission plugs.

Admit it! It has been too long since you serviced your transmission! Time to perform a fluid and filter service and while you are at it perform an upgrade that may pay for itself many times over.

- Drain Fluid and Remove Transmission Pan
- Locate the pressure switches
(Most 2003 transmissions will have five pressure switches that will need replacement. Many later trucks only have one switch. Some trucks will have a plastic dummy plug installed in place of a switch. These plastic plugs are also failure prone and should be replaced with a steel plug. Note that if your transmission has previously been rebuilt, that the factory switches / dummy plugs may have already been eliminated.)
- Remove the retaining clip and remove the pressure switch or plastic dummy plug
- Install an aluminum replacement plug and replace the factory clip. Be sure to verify that the factory clip securely retains the plug. In some cases it may be necessary to re-shape the clip with a pair of pliers if it has become deformed.
-Use wire ties to retain unused electrical connectors to the transmission wiring harness
