What is trouble code P0700?
P0700: Transmission Control System Malfunction. The OBD-II scanner error code P0700 problem is a generic code that applies to vehicles equipped with OBD-II. It refers to the transmission control module (TCM) in the automatic transmission. You may be seeing poor gas mileage or have transmission shifting problems.
When to set the trouble code p0700?
The TCM monitors the sensors and actuators relating to transmission control and communicates with the Engine Control Module (ECM) to inform it of any possible issues with the automatic transmission control module. The trouble code P0700 is set whenever the TCM detects a malfunction with the transmission controls.
What does the p0700 DTC stand for?

Why is the Check Engine Light set to p0700?
P0700 is set when the PCM detects a malfunction in the transmission control system. This malfunction causes the vehicle to set a Check Engine Light and trigger a failsafe mode.
What to do if your transmission control system is malfunctioning?
If there is an automatic transmission control system fault, a transmission-specific DTC (diagnostic trouble code) will set in the TCM. Since there is no “Check Transmission Light,” the ECM sets an informational DTC P0700 and illuminates the MIL or CEL (malfunction indicator lamp or check engine light).
What does the p0700 code in automatic transmission mean?
It refers to the transmission control module (TCM) in the automatic transmission. The P0700 code is informational. The code points to a general fault, not a direct fault.
What to do if your p0700 is having trouble?
Monitor the Slip Speed, Lockup Duty Cycle and Output Shaft Speed for irregularities. One thing to try when fixing the P0700 code is to clear the code and take it on a road test. Before clearing out the data, record all present codes and any data from the scan tests. After the second road test, look for the codes that appear.
Why do I get a p0700 code on my TCM?
The most likely reason the code appears is that the TCM detects a problem in the transmission. The P0700 code indicates a problem with the transmission. It should not be ignored, because there can be serious drivability problems now and in the future. The technician should check for all codes present to accurately diagnose the problem.
