Automatic Transmission Shifts Too Hard on Mazda MPV

While driving the Mazda MPV, operators may notice harsh shifting or slippage of the transmission. It is important to note that the check engine warning light will likely not illuminate.

This is caused by software issues in many cases, however, internal transmission failure may be the culprit as well. In some instances, the failure has been attributed to the ‘sealed-for-life’ nature of the transmission, as the transmission fluid may break down before the transmission is taken out of service.

The manufacturer of the transmission, which is a third party, has issued many software updates, but when these updates fail to correct concerns, the transmission must be removed, disassembled, inspected, and repaired.
