Mine is very quiet. I have heard Aisin only wants their guys working on the transmission not a Ram/Cummins tech where the failure involves opening it up. But, i have only heard that a few times and have no experience personally with the arrangement. So the dealer should still be able to help by either putting in a new transmission or sending it out for Aisin to fix. Depending on where you are an Aisin tech may be sent to the dealership. Keep us posted as i do not hear many issues with this transmission.
