Absolutely. It will only get worse. What was the actual purchase date? If it's within the 5 year powertrain warranty I'd get it to Mazda right away.It is barely over 5 years now, it is a very small leak, is it worth it to dismantle the transmission
Contact Mazda and find out. Could be the difference between having to pay for the repair or not. Id act quickly if I were you.It is a japan import not purchased directly from local agent, didn't know the exact purchase date all i know is that the Y.O.M is 2020
