P0700 Transmission Control System (MIL Request)
It just means that the MIL is being requested, but there don't seem to be any other codes associated with it, so I wouldn't worry about it unless a driveability or fuel economy or engine/transmission performance problem arises.

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.

Po605 and po700


p0700 is a generic trans. code, so the problem if it is in the trans. would require further trans diag. so i would scan trans specific codes first. but in most cases when a chrysler tells you it is an internal controller fault you can believe it. just make sure which controller it is telling you has a fault!

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!
