MB Paul :

Hi, my name is Paul & I will try to assist you.

MB Paul :

This is certainly one possibility but there are other possible causes.

MB Paul :

In the first instance I would be checking the transmission oil level (you need a special workshop dipstick for this) as a low oil level can cause problems & if low then top the oil up to the correct level & check the transmission for leaks (the electrcal connector seals are a very common cause.

MB Paul :

I would also be checking for fault codes using a diagnostic tool.

MB Paul :

If this is all ok then the next step would be to remove the transmission sump pan & check inside for excessive signs of swarf which may indicate mechanical wear inside the transmission.

MB Paul :

Following this a transmission oil & filter change with a flush would also be a good idea to see if the problem improves.

MB Paul :

If the problem still persists then it is likely to get quite expensive after this point - transmission removal & strip down & rebuild would be required to see if there is any mechanical wear inside the transmission or problems within the valve body.

MB Paul :

Best regards, Paul

Customer:

Hi that sounds about right, well is it possible it's could be transmission computer

MB Paul :

It is possible - although generally the transmission ECU is fairly reliable, we do not get too many issues with the ECU itself but it is a possibility

Customer:

Ok thank you for your I will check the gearbox and control unit thanks again

MB Paul :

no problem at all - please remember to rate my answer positively if I have been helpful or let me know if you need anything else

MB Paul :

Best regards, Paul
