Hey Ken,

I changed the transmission fluid a few weeks ago with Valvoline Synthetic oem ATF in the red 5 quart container. Occasionally, I hear metal to metal tap that sounds like a hammer hitting the atm oil pan. It did it again today once. I had been sitting parked in town for about 15 to 30 minutes. When I started it up and as soon as I put it in reverse to back out, I heard the tap. When I put it in forward, it does not do it. After I drive it and put it reverse before I park it again, it does not do it. When I try to get it to do it, it does not do it. Why does it make that single tap sound occassionally?

Thanks,

M D

Hello,

It sounds like you have an engine mount (torque) that is out but to be sure can you please shoot a quick video with your phone so we can hear the noise? that would be great. You can upload it here with your response. Here is a guide to help you see what I am talking about and diagrams below to help you on your car.

It doesn't do very often and don't know when it may do it again. I never considered the motor mounts as the suspect in this case.

Thanks,

I would lift the hood and start the engine while watching the engine put the transmission in forward gear then reverse gear to check the engine movement.
