P0700 Transmission Control System Malfunction OBD-II Trouble Code Technical Description Article by Dale Toalston ASE Certified Technician Transmission Control System TCS Malfunction What does that mean? Many vehicles have a control module for the automatic transmission called a transmission control module (TCM). The engine control module (ECM) communicates with the TCM to monitor the automatic transmission for faults. If the TCM detects a fault in the automatic transmission and sets a transmission related fault code, the ECM is informed of this also and sets a P0700 in the ECM memory. This illuminates the Malfunction Indicator Lamp (MIL) to let the driver know there is a problem. If this code is present and the MIL (Malfunction Indicator Lamp) is illuminated that basically means there is at least one transmission code set in the TCM's memory. P0700 is an informational code only. It doesn't point to a direct fault in the engine, only a general fault in the transmission. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module. Symptoms Symptoms of a P0700 DTC may include: Malfunction Indicator Lamp (MIL) illumination The transmission may exhibit drivability problems like slipping, etc. Causes More often then not, the cause of this code is that there is a transmission problem of some kind. The TCM detected the problem and set a code. P0700 means that a fault code is stored in the TCM. However this doesn't rule out the possibility of a failed PCM or TCM (unlikely). Possible Solutions For a P0700 the only real solution is to acquire a scan tool that will communicate with the transmission control module. Extracting this code from the TCM will be the first step in repairing the fault in the transmission. If the TCM compatible scan tool will not communicate with the Transmission Control Module then that is a good indication that there may be a fault with the TCM itself.

Having owned a trans shop in the 1990's,I would get ride of it
80% of my work,was Caravans transaxles.
Very unsafe vehicle,in the event of an accident,all van type vehicles are.

P0160....O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 2)
P0700....Transmission Control System (MIL Request)
P0740....Torque Converter Clutch Circuit
p1297 doesnt exist in my GM code list sorry but in generic codes they only have a 0 infront of them

both codes are transmission related codes,you need to have a transmission shop run a check on the curcuits

I have Dodge caravan 2010 and my falfunction light is on,what do i do?

Hello! Well - both of these codes are in reference to shift pack issues. P0700 is related to torque management, designed to reduce the RPM's at highway speed and lock up the torque converter. If it's throwing this code, there is a strong likelihood that the clutch packs are damaged. P0740 is directly related and will most likely result in the need for the clutch packs being replaced. I wish I had better news to report. :(

Hope this helps and good luck!

Hi I'm litoshop these problems your having are from the transmission p0700 is the transaxle control and the 1776 is the solenoid latching back you have to go into data and test drive with scanner on data and see which is the solenoid is really making the problem good luck if this information has been useful please let us know thank you

0605 is for an Internal Control Module Read Only Memory (ROM) Error. This is typical of a malfunctioning computer. If the computer is bad, your retrieved codes are probably wrong anyway. May need to replace computer, drive, then see if if your check engine light returns.

same thing happened in my dodge, come to find out it was the transmission module in the computer, computer needs changing out. I got the true reading from auto zone, transmission shop couldnt get right reading for a year and a half, try auto zone first, they can pinpoint your problem and its free, good luck
