		| think that the ZF shifts way to roughly! It is like that the computer does not cut of the motor when the transmission is shifting gears. I would like to get this fixed for firmer driveing and to protect the ZF unit. | 
	
 Do you see the gear and mode indicated in the cluster?
If not, clean the gear selector switch which might be dirty

Then always a transmission oil and transmission filter change is recommendable and often makes improvements in shifting.
How to do, is on my website below in the link to europeantransmissions.com

 Where exactly is the vibration? In the area of the driveshaft, or in the front axle when driving, or while braking? Steering wheel?
This might help
