What does the governor pressure sensor and solenoid do?
The computer uses the governor pressure solenoid to generate governor pressure relative to road speed, emulating what the hydraulic governor did in older ‘RH’ series transmissions. The computer varies the duty cycle to the PWM governor pressure solenoid to achieve the desired output pressure.
What does the transmission pressure sensor do?
The transmission oil pressure sensor’s primary function is to relay information to the ECM that regulates control of the transmission. However, if the switch is damaged or not sending information correctly to the ECM, the transmission may default into “limp” mode.
What causes a pressure control solenoid to fail?
Common causes of transmission solenoid failure include: Electrical issues (e.g. applying incorrect voltage to the coil) Dirty transmission fluid, which may cause the shift solenoid to become stuck open or closed.
How much does it cost to replace a downshift solenoid?
The overall cost to replace the shift solenoid in an automatic transmission ranges from $200 to $500 for a single solenoid. If the damage requires you to replace the entire solenoid pack the cost increases to between $250 and $700.

Where is the transmission pressure solenoid located?
In most cases, solenoids are located inside of the oil pan, connected to the valve body. Depending on what you drive, the technician may be able to replace just the failed shift solenoid.

What causes transmission pressure switch to fail?
Over time, the transmission oil pressure switch can wear down because of the hard environment it works in. It is subjected to heat and friction on a daily basis, so the switch can become broken, fail, or not read the pressure accurately.
Where is the transmission pressure sensor?
The Transmission Fluid Pressure Sensor/Switch (TFPS) is usually found attached to the side of the valve body inside the transmission, although sometimes it may be found screwed into the side of the transmission case/body itself.
