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 http://www.obd-codes.com/p0700

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.
the po700 code will be found in the engine controller all it means is there is a code preasent in the trans controller a good scan tool is needed to communicate with trans controller to retrieve the stored codes that specify problem
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.
code po700 is what the pcm gets from the tcm when there is a problem with the transmission-anywhere from fluid level, sensor, solenoid, tcm problem, or mechanical problem.
the situation you have with the car being in 2nd gear is called "limp-in" mode. so you can limp-in to a repair center.
