A transmission pressure oil switch reads the amount of pressure that builds up within the transmission, as a result of acceleration and the transmission fluid pump, and then
signals the vehicle's computer
.
Can I drive with a bad transmission pressure sensor?
Most vehicles are quite useless without a transmission position sensor that is working properly. Even if the vehicle will drive in in “limp mode”, that drive home will be choppy, slow and will consume lots of your car's fuel. So, try to get to
a mechanic
as soon as you notice the issue.

What happens when a transmission pressure switch goes bad?
Difficulty shifting gears
– A faulty auto transmission oil pressure switch may cause your vehicle to struggle with switching gears. This can be caused by the sensor detecting incorrect levels of pressure. Vehicle enters limp mode – Your car may enter limp mode when it a transmission oil pressure switch is failing.
How do you check transmission fluid pressure sensor?
In order to test the switch you can
connect your multimeter between the pin and the senders body
. You should find the switch is closed while the engine is at rest. When the engine is running, the switch should open. As you can see this switch has only one pin, so the switch works between ground and the pin.

What is a transmission pressure control solenoid?
Transmission Pressure Control Solenoid: DESCRIPTION
The transmission pressure control solenoid
controls the fluid pressure to the internal friction plate clutches or drum bands
. A bad or failing transmission pressure control solenoid can cause slipping, which can result in the transmission overheating.
How long does it take to replace a transmission sensor?
Q: How long does it take to replace the transmission speed sensor? Most experienced technicians can replace the transmission speed sensor within
2-3 hours
. Depending on the severity of the damage it can take a bit longer.
How many sensors does a transmission have?
Typically,
two sensors
communicate the transmission data to the vehicle's powertrain control module. The first sensor, referred to as the input sensor, monitors the speed of the transmission's input shaft. The second sensor is the output sensor, which monitors the output shaft speed.
Can you drive with a bad transmission pressure control solenoid?
Can You Drive It? The short answer is that,
yes, you can usually drive a car with a bad shift solenoid
. … Fluid pressure control should continue to function in the gear with the working solenoid, but you should avoid putting any serious stress on the transmission — towing or drag racing — just in case.
How do you check a transmission pressure control solenoid?
Raise up the vehicle with a jack and place jacks stands at all four corners to support it.
Remove the bolts that are securing the transmission oil pan with a ratchet set and slide out the pan
. This should reveal the solenoid that is attached to the transmission body.
Where is the transmission pressure control solenoid located?
Where is the transmission pressure control solenoid located? The solenoid operates through signals or voltage supplied by the electronic control module or transmission computer. They are usually located
within the valve body, the transmission control module, or the transmission control unit
.
