I havent owned it but a few weeks . has 150K on it . 2015 awd . NO CODES but slight shudder. Was thinking fluid flush and change might help. any advice ? pull battery cable for few hours to reset the tranny? Im new to this car. its a nice one but I see some big expense in my future. cant imagine the stroke I would have taking it to the dealer. I have never used a dealer to do my car work but tranny replacement might be too big for me without a lift. hoping its not that.

 

Drain and refill 3x. Don't get it flushed.
