Hello, my name is***** code means the transmission control module detected a problem and requested to turn on check engine light. These vehicles are known for the input speed sensor wiring getting damage near sensor on transmission. Next step would be to check codes with a scan tool capable of checking codes in transmission control module. P0700 is stored in the Engine control module. Let me know if you have more questions, thanks.
