the car has been running daily for +2,000 miles since i put the motor back in it possibly without the tranny ground, soo what would suddenly make the difference?
you running it hard through 1st, 2nd, 3rd. who knows, maybe the car had enough with a ground missing and now its telling you to put it on lol
only assumptions based on what your telling us, we will never know unless we are looking at it personally
