Problem overview

Some Mazda CX-9 owners report experiencing transmission failure, which often requires replacement due to common issues such as hard shifts, transmission slippage, and hesitation during gear shifts, particularly in models with a six-speed automatic transmission. Additionally, many owners have noted transfer case failure as a frequent problem within the transmission system. Instances of the transmission slipping during acceleration or displaying erratic behavior in certain gears have also been reported, suggesting potential internal issues that may necessitate component replacements like the torque converter or valve body. It is essential for owners to consult with a transmission specialist to accurately diagnose the problem using error codes such as P0981d and P0984e, which can provide valuable insights into the nature of the transmission failure and guide the necessary repair or replacement actions to ensure the vehicle operates smoothly.
