Have an 89F150 WITH 5.0 AOD TRANNY has a hard shutter from 1st to 2nd and shutters hard under low rpm I am Second also shifts rouph all the way through and in to od and reverse was wondering what's the posibel pro lens nd how to fix them

 

Most likely it is an engine miss.

 

That's just it the more runs amazing fore the most part until it reaches 1 to 2 nd gear
