Hard circuit CRV 2.2 CTDI

Hello, drive the new Honda CRV 2.2 CTDI, have problems with the switching operations. The first gear and the second can be difficult to switch, the lowest gears, i.e. four and six, can not be switched completely clean. In the workshop you have all the moving parts that lead to the transmission re-lubricated.The whole has then worked well for about 3 weeks and now the same problem is there again.Lt. Statement of the workshop is the gearbox harder to switch than with a petrol engine. Who has of you also such problems and how did you solve them?
