| Description of the problem | On 11/12/15, the radiator body around the lower transmission oil line fitting on the radiator cracked, allowing the fitting to break away from the radiator. This caused almost all of the transmission oil to be pumped into the right side of the engine compartment. The vehicle was being driven in heavy rain on rain soaked roads at 55mph on secondary roads when smoke was observed. When the vehicle was stopped heavy smoke was coming from under the hood and bottom of vehicle, but no fire started. No oil leak was observed before the incident (no oil on garage floor). Leak happened suddenly after approximately 3 miles of driving. The vehicle odometer reading was 95,510. |
