When you go forward or reverse it makes a howling screeching noise. Don't believe it to be in the transmission. The gears shift fine. Would it be the tourqe converter?

you might look at trans as the one I bought parts off of had the cluster shaft come loose and back out enough to let front of cluster fall down and wore the teeth off cluster and imput, worn or improperly meshing teeth will howl
