Help! Vibration+ Rumble uphill detailed
2010 C300 4matic.
190 000km
6 Months ago ish all the Xmas tree came in my dash. Took about 2 months to get it fixed by replacing my Yaw rate sensor with a used one. Plugged and play lights went off. No coding/calibration or anything else was involved.
ALSO within the pass 3 months ish , a more or less subtle vibration from ~2200 rpm . As soon as I release gas it goes away.
2 weeks ago I decided to replace the transmission mount.
Also within the same time frame, upon going uphill the vibration become big vibration/rumble.
I'm not sure if it's my imagination but I believe that
When going reverse a clunk came from underneath.(but only twice).
I bought the car used at 170000km and I have no track of previous maintenance. For 20 000km everything seemed going smoothly

I Highly doubt since it's only while pushing gas pedal.
Let's say I accelerate , from 1800 rpm, at 2200 vibration starts, then (ei) I keep accelerate up to 3000rpm vibration still going.
Then if I release gas pedal even at 3000rpm the vibration stops. Until I rev up to 2200rpm

Now what should I check for? Broken/ loosen bolts, bent flanges, cracked rubber?
BTW I forgot to mention that icarsoft as no codes.
