So I was driving down the road today in my 95 Accord auto, and I go to get on it just a hair so I could get around a slow ass truck and out of no where I have like no power at all! I turn off on a side road and slow to about 10mph and TRY to speed up to about 45mph and it took forever. I checked the fluid and its fine. I drove it again about 30mins ago and realize that it feels like it is skipping 2nd gear. The D4 light is flashing and all.

I dont know shit about transmissions so if anyone has any insight as to what the issue may be, please help.
