I have a chrysler 300m, it drives good, but every time i come to a stop, it jerks. i put it on a computer, code 0700 comes on (tcm). .where is it located? can i fixd it on my own?

Do you have problem with transmission?

code p0562 refers to system voltage low---or ECM power relay control--open circuit ===causes for both ---wiring---poor connection ---battery--- alternator
and wiring ---ecm relay
If the voltage is low then the ECM relay may be not able to remain closed all the time.
code p0700 refers to transmission control module (TCM) MIL ----malfunction===causes wiring ---- TCM
from the first code --it suggests that the power from the alternator is below requirement and the electronics are malfunction because of it
check all wires and connections are clean and tight
check for good ground wires on the engine and battery terminals are shiny clean and tight
I would suggest a load test on the battery as if it is failing then the charge from the alternator will be going to the battery and starving the electronics
bench test the alternator as it may be the regulator as well
TCM controls the transmission functions

The transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module (ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transaxle controls.

You need the TCM module scanned for fault codes.

code p0700 refers to transmission control system/ MIL- malfunction===causes--wiring ---TCM replace the TCM
code p0750 refers to shift solenoid9SS) A-circuit malfunction===causes --wiring---shift solenoid ECM/TCM. When the TCM is replaced then it should be fixed as the TCM is common in both faults.

Hi there:
The DTC P0700 is a Information Code The Transaxle Control Module (TCM) that monitors the malfunction of sensors and actuators relating to transaxle control. If any malfunction is detected, the TCM informs the PCM by sending a signal (P0700 code). P0700 means that a code has been set in the TCM.
This code is for information ONLY. If this code is present, check for transaxle codes. So basically, the P0700 code is telling you to check the TCM for a transaxle DTC. The TCM can not turn on the check engine light so it has the PCM do it, which can only be done with a diagnostic scanner. The self retreival method for chryslers with the ignition key will not pull up the specific transmission fault codes in the TCM.


Hope this helps.

108 Map sensor or pcm computer,113 IAT sensor or pcm,122 TP sensor or pcm, 700 Automatic trans computer or pcm, 733 Automatic trans leak or low pressure, 733 leak low pressure Your main computer(pcm) is shot start there. Then possible trans computer shot also(TCM)

You need to have the TCM scanned for codes. Autozone can only give you the ECM codes. You have code 0700 listed. That means there are codes in the TCM. When the TCM has a code in it, it goes into limp mode and locks the Transmission in 2nd. You might have a bad speed sensor.

Please don't forget to rate!


Trouble Code: P0871 (3.5L V6 VIN G Auto)
A/T O/D Pressure Switch Circuit Malfunction

Trouble Code Conditions:
Engine started; vehicle driven in a forward gear, and the PCM detected that the O/D Pressure Switch circuit indicated open or closed at the wrong time.

Possible Causes:

• Related DTCs may be present
  
• O/D pressure is incorrect, or internal transmission faults exist
  
• O/D pressure switch circuit is open, shorted to ground or power
  
• O/D pressure switch is damaged or it has failed
  
• TCM relay power circuit to O/D switch is open (loss of B+)
  
• Intermittent wiring or connector problems exist
  
• PCM or TCM has failed
  

Trouble Code: P0700 (3.5L V6 VIN G Auto)
Automatic Transmission Control System Malfunction

Trouble Code Conditions:
Ignition on or engine started. The PCM received a message over the CCD Bus from the Transmission Control Module (TCM) that it had detected a problem and set a trouble code in memory.

Possible Causes:

• The presence of this code means the TCM detected a problem
  
• TCM related Sensor has solenoid is damaged or has failed
  
• This code is for information only - check for other TCM codes
  
• TCM or PCM has failed
  

You don't replace a transmission
Worse case you remove and rebuild
