    I have been away for three months and, on returning, my 2018 3.2 Mazda BT-50 auto is making a clunk noise when going into drive or reverse. Do you know what may be causing this?

    The first thing to do is take a look at where the car was parked. You’re checking for a pool of transmission fluid that has leaked out over time while the car has been stationary. A low of fluid can cause all sort of problems in an automatic transmission, including the one you’re experiencing.

    However, the transmission in this vehicle is well known for noises when selecting gears from Park, particularly after it has been sitting for a while. The problems were usually traced to the valve body of the transmission and some valve-body assemblies were replaced as part of a technical program conducted by the manufacturer.

    The catch, though, is that the service bulletin involved suggested that only transmissions in cars built up to 2014 were affected, and since your car is a 2018 model, it shouldn’t have the same problems. But it wouldn’t be the first time a problem thought solved by a car-maker has resurfaced in subsequent models.
