3.3 L engine, between every shift, there is a loud rumble and vibration, the mechanic says it is the torque converter and needs to break in, it has 3000 miles??? The noise sounds like a truck at 60mph
noisy on 2009 Dodge Grand Caravan
That does sound like symptoms of torque converter engagement issues. Is this a dealer mechanic that told you this? It sounds like your van is brand new, maybe try speaking to the service manager to see if another technician can look at it and check service bulletins. Has it done this since new?
I have a 2009 shakes like crazy when I stop...Roters front and back are bad. Had resurfaced at 12,000 and 18,000 miles...fighting to get new ones
