Hi everyone, I just want to know what is the problem of my GD, it is japan import. Every morning I warm up the engine 5-10 mins and from there engaging from PARK to DRIVE, a strong vibration is coming under the hood ,sometimes a 1-2 knocking sound before the cars accelerates slowy even though it is in DRIVE already, the vibration is stronger if I turn ON the A/C. But all goes to normal when I drove the car longer. I just change the Honda CVTF oil 2 months ago, clean the CV Valve body and 1 yr old transmission support, 7 months old engine support, car is 120k mileage.

Any help or suggestions will be a big help
Thank you!

 

This is also my problem. Have changed my spark plugs, cleaned up the carburetor, replaced all engine mounts, still nothing has changed. It also vibrates when I stop the car on DRIVE (Especially when A/C is on).

 

Not seeing it, my first guess would be transmission mount.
