Automatic gearbox problem

[RhysMT]

Hi,
I've got a 2006 A170 that sometimes won't select drive (if I'm stopped) or slips out of drive into neutral at low speed - has anyone have an idea what is happening, and if it will be expensive to fix?

Thanks in advance,

Rhys

Assuming this is a proper automatic and not the semi automatic 2 pedal manual gearbox it could be low pressure in the gearbox hydraulic system. How many miles has it done and when was the last transmission oil and filter change?

It's a CVT Alastair - they dropped the silly clutchless box with the end of W168.

Rhys, it is most likely what LostKiwi said above - get the ATF and filter changed, and check your service book - it was supposed to be done at 37.5k miles or 4 years.

I was advised to do the transmission oil change every 35-40k miles (same year, same CVT as yours), rather than just once at the mileage above - I had the first one done recently and am going to follow this advice.

Also, when you start from cold, do not shift into gear, until RPM drops below 1000 - this is from Des (aka Forrera) - he does almost exclusively W168 / W169 and has a wealth of knowledge on these models.
