Vibration in reverse - any idea?

Vibration in reverse - any idea?
This one has me baffled.
I backed my car up my driveway yesterday and noticed this "vibration".
Here's a list of knowns.
- Shifts into every gear as it should
- No slippage
- When I shift in to R, it engages as it should. No funny vibration in R
- When I apply gas in R, I feel it. Through the steering wheel/body
- If I back up by "creeping" in Reverse (no gas applied), there's no vibration.
- Transmission fluid is at correct level. Car was properly warmed up and the I checked the fluid with the engine idling. Fluid color was cherry red
- I backed up going straight, left and right. Symptoms seem the same backing up straight, left or right.
- It is a bit cold around here recently - about 40ish (Fahrenheit).
- Vibration doesn't get worse the higher the RPM.
- No Vibration when I rev the engine in Park or Neutral or in Drive.
- Car drives just fine in Drive. No vibration.
- Engine is in good shape.
Any ideas?
I'm wondering perhaps engine and/or transmission mount maybe going bad....

I might be going out on a limb here but, maybe try jacking it up, put it on stands and run in it reverse, just to see if its a load only ordeal. I know you said it's only when you apply the gas, but just try giving it throttle off the ground and see if anything changes.

i have had the same prob but i have a manual and instead of a slight vibration it bucks violently and locks up abruptly and stalls i think it is the cv joints bc it makes a lash noise in 1st -5th at any speed but not in nuetral. still goes into gear fine but it got stuck in 1st for a little bit but only happened once also think it could be throw out bearing, clutch, or i spun reverse i could use a second opinion b4 i spend all kinds of money
