The additive can also be found at most auto parts stores, if you try it just add it into the transmission along with the new fluid and then drive it for a days to see if it helps as it usually does take a little bit for the additive and new fluid to do it's thing if it is a shudder issue.

I inspected the transmission fluid level with dip stick. It came out to be cherry red without any residue. Was not expecting it to be this clean. Then I tried to get under the body to inspect and realized its easy to drain the transmission fluid by opening the plug as its very much doable without using any lift/jack stands. But for engine oil drain it would need some lift as the area seem to be covered with rock guards and there's not much space to get under it without lift.
Coming back to my question of vibrating sensation, looking at the way transmission oil color shows my instinct says it does not seem to be having any problem there.
Since, we're talking about engine/transmission I just wanted to mention that I am consistently getting 17-19 mpg in City and 24-25 mpg on Freeways.
If there were some issues with transmission/engine are these fuel mileage do able?
What other things could be suspected for vibration?
