Car Shaking on Medium Speed

Hi.

I have a 2008 Honda Accord V6. It has done about 95,000 Kms and in great condition.
The car shakes when I drive normally between 40 and 60 kms and is less obvious at higher or speed. All services are up to date and tyres are in good condition.
When I drive in S gear, then the problem completely goes away, however I don't want to drive in this mode all the time.

Three Mechanics have not been able to diagnose the issue correctly. They suggest it may be Transmission but I am not convinced. Gear box oil change a while ago and quite clean.
No lights flash on the dashboard and engine mounts are good. Also, suspension is good too.

Any idea?

CV joint.

wheel balance

Place ya bets.

Thanks. Hope it is the CV Joints only.

The tyres are quite good and balanced 6 months ago to ensure the problem would not happen.

Now I can take it to another Mechanic and ask them to check it out.

Inner CV joint. Had the same issue on my Accord Euro. Vibration was at 55 km/h only, and only under throttle. It would also vibrate at twice that speed, 110 km/h, which was obvious on the freeway.
