Have Honda Questions? Ask a Honda Repair Expert.
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.the code P0700 indicates that there is a code in the automatic transmission and that code is the P0740. The code P0740 is a Lockup Clutch System Problem and it not uncommon to have to replace the transmission for this code. Neither of these codes will cause the battery light or Maintenance light to come on. Are you having any issues with the transmission?I have enclosed the pinpoint test for the code P0740 in the link below, copy and paste the link to your browser to open and view it.
If the code P0740 is still setting after you clear it then the computer system is still seeing a fault. I would suggest you return to your builder and have him recheck it.
