Driving down the highway one day around 65mph the vehicle began to shudder violently, reducing my speed to less than 45mph all the way home (all the while still shuddering) I took it to a well known transmission shop "whitty transmissions" in oak ridge NJ only to have them drop the pan and find the transmission flooded with metal chips costing me a $3900+ rebuild. My transmission failed at 87,000 miles.
