Works fine for about 15 minutes just long enough for engine to get hot then stalls in low gear and will not leave that gear. Once it gets cool drives and shifts like a dream for awhile until you stop for a stop for a light, after that will not leave low gear.
What makes Transmission stick in low gear on 1995 Plymouth Voyager
Its probaly going into fail safe mode that is in 2nd gear. Transmission is computer controlled and it has sensor inputs that give problems. Could be several different things that can cause this problem. Check your fluid level first and then have a professional do diagnostics for you.
