I have a snap on graphing brick. I pulled trans codes myself and there are none. Most of the time it works fine. But if I get straight on the freeway in the morning it will: work fine, not shift out of second no matter the throttle position (if I manually shift into neutral and back it will still go into second even at 55mph) and once it downshifted into second from 3rd while under acceleration. It takes about 1 to 2 minutes and it will start working fine. It has never happened while warm. Also occasionally it will be slow going into reverse.
