Mysterious Noises

Hey Everybody,

Recently, every time I turn off the ignition, I hear a sound coming from my engine that sounds like it's still turning. I've had a buddy turn the car off while I was looking at the fan, belt, and pulleys and I can't seem to see anything turning after the ignition is off, yet the sound is still present. It doesn't really sound metallic but I'm not sure what it is.

Also as of late, sometimes when I shift into reverse I hear a loud popping noise. When I shift back into drive, sometimes I hear it again and sometimes it does it when the car shifts from 1 to 2. Not sure if this is suspension or transmission related but it's starting to worry me.

I have no CEL's or any other coding issues so I don't think any of these problems are really bad but I'm starting to worry. I was driving last night and the car felt like it was shuddering. I'm not really sure if it's due to something rubbing or an engine issue but like I said I have no codes as of right now.

I've had the transmission rebuilt before and the engine has less than 10,000 miles on it since it was rebuilt. Mods are listed below. Any ideas of what these could be? I plan on going to a shop Wednesday but I wanted to know if any of y'all had similar issues.

On the popping - check all THREE motor / transmission mounts (two motor, one transmission). Also the U-joints (popping when shifting from D to R and R to D? Prime trait of a blown U-joint!)

You'll have to use a stethoscope (which can be a long screw driver!) to find out what's still spinning. Could be the compressor itself, could be the fan, could be anything else.

The Sound After Your Ignition Is Off Might Be An Automatic Antenna.
