Greetings,

The stick sometimes comes out of first gear.  
Now, I’m not sure, the transmission is faulty or something is wrong with the shifting mechanism.
I notice, that the stick is shaking while driving, and I thought, maybe the shaking can jump it out. 
So, what may cause the shaking, if that is the culprit?  
Or if it’s the transmission, what maybe the problem?

Thanks to all the great minds on the List.
Zoltan
