Tranny probs
 

I know this is a forum for classics, of which I have '65 coupe, but my other car, a '96 GT Convertible Mustang, has this sound coming out of my automatic tranny when I hit third and overdrive gears. The sound is something of rumble, somewhere between a flutter and just loud vibration. I was looking to see if anyone has ever heard of this on any tranny, and what I'll have to do to it to repair it,(hope not replace it). Rev, I hope you read this post, you're always a lot of help. Thanks!

Sounds like your 3rd clutch pack. That applies when shifting into 3rd and stays applied while the od band applies when shifting into od. They are typically weak links in AOD type trannys, although not as bad on your model as the older ones. Only solution is to rebuild at least that clutch pack.

Thanks a lot for the reply, that's exactly what it sounds like to me. What parts would I need to perform the rebuild, or would it just be better to take it to a shop and have it done there?
