Diagnosis & Recommendation - Whining noises normally relate to the transmission, however in this case there was a technical bulletin that referred to this exact problem. The tech bulletin advised that the timing chains and timing chain guides needed to be replaced in order for the issue to be resolved. We also recommended replacing the water pump, thermostat, tensioner, idler and serpentine belt while we had front of the engine removed.
