Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hello, my name is***** for the question. Will it make this noise revving the engine in park?
Thank you. Most of the time if this happens only when slowing down it is caused by an issue within the transmission. There are issues within the transmission that will cause the clutch packs to make a noise like this. One other failure I have seen to cause this is a failure in the cam timing actuators. This can occur if they are failing, but can also make noise if the engine oil is low or if the oil is not changed often and there is some sludge build up.
