Default Chirping from engine area in reverse only under load

I noted a high pitch chirping from the engine area when auto trans is in reverse. No noise until I put it under load. No noise in neutral of forward gears. Any ideas?

You have to be more precise in where the noise is coming form by using a rubber hose to your ear and listening. Becasue you did not write that you have to be moving in reverse...under a load.

I can start rattling off possible things it can be...but...it would be easier if you centralized the noise..

It sounds like you have a broken right-side motor mount that is allowing the engine to lift up which is causing the fan to hit the inside of the shroud. With your hood open and the transmission in REVERSE give it some throttle and observe the engine.

Checked that out and it was a negative. Watched the torque and put it on my lift and could see nothing wrong with the mount. It has stopped now and I am watching. Will advise if I come up with something????
