1995 Toyota Camry Transmission shifting

Transmission wont start from rest in first gear unless shifted manually then works fine. It also tries to start in second gear after coming to a stop. After it is hot it works as designed(starts in first and shifts normally). I am also having an intermittent blinking of the O/D light as well as a "check engine" light. Car runs as if nothing is wrong except for this. Just had trans serviced and oil level is full.
