Hello All,

I am having problem with A-Class automatic Merc. On the speed meter its coming up with F even though its in parking and when i change it to REVERSE or to DRIVE i get really strong jerk how ever when i drive it doesn't change gear. i checked transmission oil level which was low but i top up with more transmission oil with the exact level.

Will someone please help me as i have asked few people/garages and they are giving me different answers and options which is very expensive for me, if its just a reset thing and it can be fix with low cost where and what should i do.

Your answer to this thread will be much appreciated.
