Hi, I'm new.

I recently was leaving my home when I turned my 99' accord on and my D4 light was constantly blinking. I could reverse, put it in neutral and everything like normal but I could not get an acceleration. Felt like my transmission was slipping? My car knowledge is very limited so any light shed on my issue would be greatly appreciated. On a side note, I take very good of my car and do on the normal maintenance when its needed immediately.

Car has 136K miles BTW.

Thanks for anyones help in advance.
