check engine light came on recieved codes po700 eatx controller.

My information says when you get a P0700 code use "DB3 scan tool and use it's diagnostics to look for transaxle faults."

Hello the vehicle is in limp mode and the fault code [P0700- AUTOMATIC OVERDRIVE TRAMISSION WILL NOT SHIFT OUT OF FIRST GEAR OR WILL NOT SHIFT OUT OF SECOND GEAR].The speedometer may not work properly or not work at all,this will stay this way until the next key cycle.You are welcome to have a complete diagnostic performed at RECO'S RENCHES ina Pittsburg,Ca.418 E.10th Str.HAVE A BLESS DAY from DR.
