1999 Ford Taurus 6 cyl Front Wheel Drive Automatic 126784 miles
started up fine went into reverse a little slow put it in drive still a little slow drove for 5 min slowed down then tryed to speed up would not change gear put it in park let it sit for a few mins now it wont go in to any gear no check eng lights eng runs fine just stop going in gear.
Green od light blinking by any chance? Trans issues may not necessarily set the check engine light. Tow it to a locally owned reliable trans repair shop for diagnosis. My 99 trans failed at 65k, planetary gearset fractured. 1450 for a rebuilt. Hopefully yours is otherwise. A lot of trans issues do not turn out cheap and simple. Good luck
