Hello everybody from France ! I have a Cruise-o-matic medium case on my 64' Mercury and after my vacation my gearbox make a bad noise from the converter (I think because when you are under the car and you listenning the gearbox you can heard a lot when your are under the converter and the same noise but not so loud when you are under the oil sump.) If anyone have an idea of the part can do this noise ... maybe the converter ? Maybe the pump ? Maybe a bearing ? The noise ride with your rpm and became more quiet after 50mph... The torque nut of the converter is ok, the starter is ok, engine is really good ... Video : http://dl.free.fr/jIBhTqBk5 Thank you so much, sorry for my bad english and I hope you can see the video !
