Honda transmission problem

2003 Honda accord 4 cylinder original owner. About a month ago in rain when in red light and rain wanted to move because of little treads of tires the car skid and then some noises in the engine and didn’t move again. I towed the car to the drive way and its sitting there since. After checking youtube and other sources I have no idea what is wrong with it. I took out both solenoids check for malfunction and cleaned them. Never changed the transmission fluid but topped it when necessary. When I start the car and put it in any gear does mot move and make noise and the worst is when I put it back in park position. I want to flush the fluids tomorrow and put fresh one as I heard it may help. Need your help people. Thanks in advance
