2001 pt cruiser engine light code P0700/ p1284

Well p0700 is a transmission code and the related repair on alldat is a error in tcm module! sounds like a bad computer but i couldn't say unless i tested it myself! sorry for lack of info and the other code was not in the list but there was a 1294 and that is a "target idle not reached" so i would be looking at the throttle body and clean it and make sure nothing is binding and aso vacume leaks throught the motor! good luck

P0700 is a pcm trouble code that basicly says there is more trouble codes in the trans controler side of the pcm.
in order to find out what those codes are you will need a scan tool and then once you have the codes further diagnois can be done.
depending on what codes come out of the trans controller it could mean something simple like a bad speed sensor or something bad like a loss of prime. gear ratio error codes can be caused by faulty sensors.
