Pressure Switch Plugs
Fits 5R110W 2003-on
- Distributor Part Numbers
- Tech Notes
Early valve bodies contained 5 pressure switches that were never used nor monitored by the computer. In later valve bodies, the holes and the switches were removed with the exception of the direct clutch, which retained the hole in the body with a plastic dummy plug installed.
It is common during the extreme pressure that breaks the low reverse lugs out of the case to also damage the switches or a dummy plug, particularly the direct clutch dummy plug.

- General Details
Ford vehicles equipped with the 5R110W automatic transmission often have damaged pressure switch diaphragms as well as a broken dummy plug resulting in slip complaints and solenoid performance codes.
Early valve bodies contained five pressure switches that were never used or monitored by the computer. In later valve bodies, the switches were removed except for the one in the direct clutch circuit which now uses a plastic dummy plug. With the excessive high line pressure problems that plagues these units the switches as well as the plastic dummy plug often fail and create hydraulic leaks in the circuit.
Features and benefits:
This TransGo 5R1-PLUG-PS kit includes five new aluminum plugs and O-rings in case you need one or all five. These plugs will replace either a pressure switch or a dummy plug. Replacing pressure switches that the computer never monitored in the first place with aluminum plugs is good preventive maintenance during overhaul.
Corrects/Prevents/Reduces:
- Pressure loss
- Delay engagement
- Slip or flare shift
- Solenoid performance codes
- Clutch failure
Includes:
- (5) Aluminum pressure switch plugs
- (5) O-rings
