When a mechanic goes to diagnose a serious problem with your vehicle, they will usually hook up a scanning tool to the power control module. The computer of the module will then provide the scanner with a troubleshooting code which signifies the problem of the vehicle.
For instance, the diagnostic trouble code “P0700” signifies that the transmission control system is experiencing some type of malfunction. Some vehicles may give you this code automatically on your dashboard while others will require a scanning tool to find the code.
The first symptom that you will experience from a malfunctioning transmission control system is the “Check Engine” warning light illuminating on the dashboard. This will be followed by the failsafe (or limp home) mode being activated until the problem with your transmission control system is fixed.
While under failsafe mode, the central computer of your vehicle will work to reduce the damage as much as possible by altering the revolutions per minute of your engine and the shifting of your transmission.
Common Causes of a P0700 Trouble Code
When you receive the trouble code P0700, there might be one of four causes for your transmission system malfunction. Below are the 3 most common causes.
1) Transmission Solenoid
This is the component which allows the transmission fluid to flow into the body of the valve so that it can make contact with the appropriate gear.
2) Transmission Valve Body
This will ultimately cause the transmission to fail because the valve body is the transmission’s control center.
3) Transmission Control Module
This is the separate computer which controls the functions of the transmission. If that goes bad, then the transmission will go bad.
