I am looking at buying a 1989 LX vert 5.0 with an AOD in it. I'm a lil leary on it though because the transmission takes forever to shift gears. I know some older cars have vacuum modules that control shift points. Is this the case in the 89 AOD?

Any help would be greatly appreciated.

I can get the car for $800, it neeeds some work but seems relatively mechanically sound as far as running and such with the exception of the Trans. It needs a rear window but I know that is relatively easy as I've done it before. other than that it needs painted and thats about it.

Thanks guys
