Theory of Operation
The Transmission Control Module (TCM) constantly calculates the transmission ratio based on the input speed sensor 1 and 2 (N2-N3) signals and the calculated output shaft speed. The intent of this diagnostic is to detect if the transmission is slipping or an invalid gear ratio is present.

  • When Monitored: Engine RPM greater than 450 RPM , output speed greater than 180 RPM , no N2 - N3 input speed sensor errors present, no gear selector lever errors present, no ABS system errors, and all wheel speeds above 450 RPM .
  • Set Condition: No shifting operation and detected gear is not the actual gear. No shifting operation - detected (calculated) gear is less than actual (expected) gear, no plausible gear is calculated, actual turbine speed - calculated turbine speed is greater than 300 RPM or calculated transmission ratio is above threshold. During an Upshift detected (calculated) gear is less than actual (expected) gear. During Downshift - detected (calculated) gear is less than actual (expected) gear.
Possible Causes
Always perform the NAG1 Pre-Diagnostic Troubleshooting procedure before proceeding. See: Transmission Control Systems\Testing and Inspection\Procedures\NAG1 Automatic Transmission

Diagnostic Test
With the scan tool, check transmission DTC's
Are there any solenoid and/or solenoid supply voltage DTC's present?
YES >> Refer to the Transmission category and perform the appropriate symptom(s).
Check the transmission fluid level.
Is the fluid level correct?
YES >> Go To 3
NO >> Properly adjust the fluid level.
Perform NAG1 TRANSMISSION VERIFICATION TEST - VER 1. See: Verification Tests\Transmission Verification Test 3. CHECK IF DTC IS CURRENT
With the scan tool, record the Environmental Data and erase Transmission DTC's. NOTE: If the TCM detects and stores a DTC, the TCM also stores the vehicles operating conditions under which the DTC originally set and is located in scan tool under Environmental Data. Before erasing any stored DTC's, record any available data to assist in duplicating the conditions in which the DTC originally set.

Using the Environmental Data recorded earlier, test drive the vehicle while trying to duplicate the conditions in which the DTC originally set.
Did the DTC P0733-GEAR RATIO ERROR IN 3RD reset?
YES >> Repair internal transmission as necessary.
Perform NAG1 TRANSMISSION VERIFICATION TEST - VER 1. See: Verification Tests\Transmission Verification Test
NO >> Go To 4

The conditions necessary to set this DTC are not present at this time.
Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
Wiggle the wiring and connectors while checking for any possible open or shorted circuits.
Check for any Service Information Tune-ups or Technical Service Bulletins that may apply.
Were there any problems found?
YES >> Repair as necessary.Perform NAG1 TRANSMISSION VERIFICATION TEST - VER 1. See: Verification Tests\Transmission Verification Test
NO >> Test Complete.

    Ignition on and battery voltage greater than 10 volts .

    An active DTC is stored in the TCM. One Trip Fault. Three good trips to turn off the MIL.


    DTC present in the transmission control module
    Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

    Diagnostic Test


    This is an informational DTC letting you know that a DTC(s) is stored in the Transmission Control Module. Erase this DTC from the PCM after all Transmission DTC(s) have been repaired.
    Using a scan tool, read the Transmission Controller DTC and refer to the Transmission Category and perform the appropriate symptom.

    Test Complete.

What is code po700

It means there is at least one transmission code set in the TCM's memory. P0700 is an informational code only. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module

My 2004 chrysler concorde throws codes po562 and po700 and will not start unless i have my battery charger plugged up to it. What could this be?

get a good battery into it and you should be fine. I don't remember where they hid the batteries on that one, but if it's in front of the left front wheel you will need to clean the contacts and test your battery because that configuration was problematic.

PO700 PO740, check engine light on. Run a test on

PO700 is a code telling you there are codes in the TCM of some late model cars where the Transmission control module has lost connection to the PCM the vehicals main computer , And basically it happens when the TCM has a issue within itself or the transmission that sets a code and it sends a request for the PCM to illuminate the SES or CHECK engine light.
PO740 is a chrystler specific code that involves your Tourqe Converter Clutch Circuit (specifically The TCC solenoid) this code if not repaired quickly could cause major transmission problems....slipping out of gear....not shifting from first to second properly and just all around trans problems...eventually leading to no shifting at all...I highly recommend fixing it soon.

Po700 and p1776

P0700 is EATX code present. It simply means that the engine computer has noticed that the transmission computer has a dtc in it. This causes the Pcm (engine computer) to turn the check engine light on. You will need to have the TCM (trans computer) checked for codes to know what to diagnose.

error code P1776 - Replace rear solenoid switch

Likely both related The P1776 probably kicked off the P0700 notification.

Hope that helps! Happy Motoring!
