Knock/pop sound at low speed accelerating/breaking/turning
 

Hi, have a 2004 xc90 T6 106,000 miles and just had the trans rebuilt and they also said they replaced the engine mounts and rotated tires.
Now trans works fine but there is a single knock (like someone poping thier knuckle) coming from engine when accelerating after stopping, sometimes when coming to a stop and doing sharp turns. You can also slightly feel it.
It never happens a high speeds, mostly happens when accelerating after coming to a stop.

Anyone experience this?

I appreciate any feedback!
Thanks
