Every 200 mi or so of 80/20 in/out town driving, it wont shift into 2nd. this happens after leaving stop sign/light. I have driven it slow till it shifts (off the side of the road) and it has shifted in as soon as 2 blocks and as long as 1 mi. I have had luck on pulling over and restart, shift in reverse, sat and waited 5 min., though none of theses were repeatable corrections to find a solution. I have had a trans flush and fluid level is correct.
Dose this sound major or minor, and is there anything to try to narrow down the cause?
