2012 Dodge Grand caravan shudder while driving what are possible causes.
It could be a symptom of transmission going out. But it can also be a heat shied on the cataltyic converter that is loose.
Do you hear it when stopped at a stop light with the transmission in Drive?
Do you have any light on ( check engine or whatever) ??. Could you share a video with while this problem is happening maybe we can give you better advice.
On loose heat shield.
I have a scan tool I ran a diagnostic test there are no codes.
Does it shift properly between each gear?
either tranny, heat shield of engine support. hopefully not tranny. but considering you are not getting any error codes - could be just the latter two.
