my 2000 ml430 has a problem at gearchange.
it takes too long to select gear and makes the engine rev during this process.
its been on the diagnostic computer with no faults and no engine lights on dash come on
can anyone shed some light on this

 

Need more specifics. Do you mean when it up-shifts, or when you first put it into gear ???
What equipment was used to test ??

 

not sure but was in mercedes and they said it was on machine for testing for faults.
its when it changes up.
it has lost drive once when i put it in gear
