97 civic, automatic transmission. Replaced the radiator yesterday, and some tranny fluid came out when doing so. So i added what i thought was lost and when i started it up and put it in reverse the check engine came on along with the "D4" light blinking. the car wont go now. When i accelerate the car doesnt respond like it should. I plugged an ob2 scanner in and "P0700 & P0758" came up. Please help. :'(

 

did you unplug anything to get the radiator out? go and check everything is pluged in good, no grounds are disconnected and check all your fuses are good.

 

Everything is plugged in correctly. Not sure about the fuses. Some tranny fluid was lost while replacing the radiator but i topped it off and checked the level and it was fine.

 

You probably accidently unplugged the shift control solenoid. It's close to where you were working.
