Noodles, the transmission he has is a manual gearbox that does not require the use of the clutch. The W168 A class uses an automatc clutch to shift gears. Some W168 actually had a manual gearbox with manual clutch and some with automatics. Those sequential transmissions are not offered for the US market. Mostly european markets can have them as an option.
Faustino, you might have issues with the clutch actuator. usually first and reverse require the clutch to overcome resistance and has to create kinetic energy to move the vehicle, therefore the jerking. It can be caused by a bad clutch, but most importantly, the automatic clutch might be failing. I would see if they have the proper equipment to re-teach the clutch friction point. If all fails, it probably has to be replaced.
I am not too familiar with the construction of this transmission, but if it has clutches like the A Class, the A class had issues with one of the clutch packs having stress cracks and it would cause a jerking hard shift when engauged. Cheers!
