vibration when shifting problem
My car is 2010 S350 vibrates when shifts I think after the third gear or the fourth gear but when does this happens ? usually when I start the engine when it is cold I start it, wait for it until it warms up thin I drive the car at a straight road, when it shifts from the 3rd or 4th cannot tell, I feel it vibrates when it shifts at these gears only and after driving it for a while there was nothing no vibration even when I shutoff the engine for an hour and start it again and driving it also tried Manual shifting tried every gear there was no vibration ! but when I stop the car and turn it off leaving it for another day same problem comes again ! First I thought that it was the transmission mounting so I replaced both the transmission and engines mountings but nothing really changed I stopped my car till another day thin I start it and driven it and same vibrating happen but it was not like before it is not strong but I can feel it a little. so had any one this problem before ? also the previous owner replaced the transmission oil at 60K KM when I bought it, it was at 110K Km, now it is 128K KM I will replace the oil but first I wanna now what is the problem

could any one help me please ?
