I have a 93 f150 with 102k on it. I have code "T" on my sticker, which I see is an AOD. When accelerating slowly, I hear a low whining sound coming from I guess the trans. I also notice that when I am slowing down, for say a curve, and then give it gas after the curve, the trans doesn't shift up for acceleration. It is as if I am driving a manual with it in 4th instead of 2nd. I have to push hard on pedal to get it to shift into a lower gear. Otherwise, it drives fine....no slipping or vibrations. I have no idea when last trans flush was done.

Any ideas on what to do? I would guess a flush and fill would be in order, but any other fixes come to mind?

 

Can anyone offer any help?

 

not quite sure about the whinning. other wise sounds normal to me. but ive never driven an AOD I have an E4OD. so i dont know there caracteristics specifically.
