I just got word from the dealer installing my jwt clutch/flywheel and new tranny, and not only were my belts cracked at 37k, but my ac belt was completly gone!!!! Anyone else run into any problems like this, Also does the turbonetics void the powertrain warranty??? I thought the magnuson/moss case covered all of us aftermarketers... Any thoughts or ammunition to aid me with Nissan would be greatly helped.
