I have a 2004 4 door short bed automatic truck that I just bought from Florida. It had a bad carrier bearing when I bought it so I thought that was the issue. The truck shifts and moves great until it locks the converter in od and the truck shakes and shimmys. As soon as the converter unlocks its fine again. Is this a symtom of the converter going bad or should I check other things first. Rear Driveline is tight all ujoints are New. Someone had told me to have the injectors checked.. It just have a slight weird idle but it doesn't haze or smoke or anything. There is no check engine line on and I have check for soft codes. Truck has 170k on it and it's solid. Just looking for some help!
