Trans wont shift from 1st to 2nd without letting off throttle
I have a 99 2wd with a 3.0 auto. When the trans shifts from 1st to 2nd I have to let off the gas to get it to shift or it will shift at like 3000 rpm on its own but the od light will flash untill I restart. Trans shifts great in all other gears. Is there anything I can do or is it DOOOMED?
