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.

I don't have anything to tell what the codes are, but you may have a bad CV joint or shaft. Have struts checked too.

Hi Leetroy, I'm glad to help! The P0760 code you have is: Transmission Solenoid Pressure Switch Assembly. The problem could be in the wiring, it also could be the solenoid assembly itself or it could be the engine control module (PCM). It will need to be checked out to verify which part is bad. Hope this helps and have an awesome day Leetroy.

P0700 is an information code from the transmission controller to the engine controller(computer) it says "hey I'm having trouble making the trans do what I want it to!" P0740 is a trans code saying that the TorqueConvertorControl system isn't working. Could be the solenoid pack, valve body or the torque converter itself. I would recommend to leave this for a pro! $1400 is a fair price.

P0740 Torque Converter Clutch Circuit Malfunction

Sounds like the auto transmission is having or about to have some issues. Normally you will see the engine running faster than is should for the speed you are traveling. get your transmission checked out soon

P 0700 = EATX (Electronic Automatic Transmission Communication) Controller DTC Present. = An automatic transmission input DTC has been set in the transmission controller.
P 0740 = Torque Converter Clutch. No RPM Drop at Lockup. = Relationship between engine speed and vehicle speed indicates no torque converter clutch engagement.

Yes the Fluid and Filter Change should take care of this. However, Dodge, Chrysler, and Plymouth Minivans have had alot of Transmission problems over the years. Make sure that whomever changes the Transmission Fluid that they use exactly what is specified. Also, do not let any Mechanic talk you into a Superflush of the Transmission. This procedure does not change the Filter.

Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

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

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!
