I have a 1990 ford F250 diesel truck with turbo and automatic trans. the transmission started shifting hard. within two block one hard shift and the truck went out of geart and will not move. I was told by one transmissions shop that is a very typical of a tourqe converter to fail. Replacing the converter should fix the problem A second shop said no way and that the transmission should be replaced. Is this a typical T.C. failure or ?
If anyone has an idea.
thank you Dennis
