Vehicle is 2013 Honda Civic DX with 210, 000 kms and 4 speed auto transmission. When accelerating gradually in D, there is very noticeable shudder coming from the front, likely from transmission. it happens more when the engine is still cold, less so later on but still does. It is espescially easy to hear and feel when going uphill.
It typically starts around 29 kmh until about 40 kmh, which I think is the lower range of second gear. There is no engine warning light coming on yet and technicians at Honda dealership and another independent mechanic could not pull any codes to work with. What could it be and what can be done about it?

 

lol doubt you took it to the dealer because they would have inspected it... im sure you pulled the codes and it was fine and obv not throwing any codes if the CEL isnt on.... at 210k miles its going to be due for engine and trans mounts im sure , could be a knot in a tire , if not competent enough to diagnose it take it to a mechanic/dealer
