how come my OC light flashes while I'm driving and the check engine light turns on solid then it feels kind of like it downshiftsor like it stays in neutral but it still runs poorlyit doesn't overheat or nothing

What is your question?

my O/d light turns on it blinks and the check engine light stay solid yellowand ask if I'm going 35 40 miles per hour I like goes into neutral or shifts down and when I park and leave it in park sounds like the engine is celebrated
