5R110 Transmission Dummy Plug (2003-2010) Ford - 36940-17K

2003 - 2010 Ford Truck Owners

For only a few dollars and minimal labor, you can potentially prevent a catastrophic transmission failure and a costly rebuild!

APPLICATIONS:
Vehicles running a 5R110 Transmission

        Many Powerstroke owners spend thousands of dollars 'bulletproofing' their engines. How about showing the transmission a little love? 

The PROBLEM:
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. 

The SOLUTION:
Replace the unused pressure switches with machined steel o-rings plugs that will never fail! Once the transmission pan is removed it takes only minutes to perform this upgrade.

INSTRUCTIONS:

• Drain Fluid and Remove Transmission Pan
• Locate the pressure switches  

          On the 5R110, Ford installed plastic dummy switches and plastic dummy plugs. They are both failure prone and should be replaced with a steel plug. (if your transmission has previously been rebuilt it they may have already been replaced) We recommend dropping the pan and looking to see what you'll need before you order, or just ordering 5 plugs. Return any unopened plugs when you send in your EPC solenoid core and we'll refund your purchase amount on them. The chart below will help you determine how many dummy plugs you might need:
'03    5 dummy plugs 
'04    a transitional year, with anywhere from 1 to 5 
'05   1 switch

• Remove the retaining clip and remove the pressure switch or plastic dummy plug
• Install a steel 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
