Transmission problem
2001 Volvo S40 4 cyl Front Wheel Drive Automatic

I just finished repairing an idling problem by replacing the ECT sensor. The Idle control Valve cleaned and was not the problem. While test driving the car, it all of a sudden shifted very hard, a check engine light came on and an UP arrow became visible blinking. When I got it home the following error codes were present: 700 and 704/705, not sure which of these codes were present. One or the other either way. I have not yet checked the fluid level in the transmission, but the car has not been driven in over 5 months. Any ideas

The check engine light will have a code to indicate the transmission control module has posted a trouble code since the arrow light is. Now for PO700 codes, those will be transmission fault codes and I can not seem t find info on 704/705 codes. Is it possible for you to have the transmission control module scanned for codes?
