727 no 3rd gear

I would talk to a few guys on ur area that may be able to recommend a good mopar tranny shop. I would tell the builder of the issues ur having even though he should spot anything out of the ordinary.u can ask the builder if he found the problem or is at the very least he is fairly confident it's cured. My experiance with a stuck shuttle valve is a little harder upshift. I personally do not think u have a governor problem. Kim
