Problem overview

Some INFINITI M37 owners report experiencing transmission slipping, which can lead to symptoms such as locking and difficulty engaging drive. This issue can significantly impact vehicle performance and safety, resulting in erratic driving experiences. Symptoms like engine RPM fluctuations are often among the first signs of transmission problems. Additionally, owners have reported varying severity levels of transmission issues, including hard shifting and complete failure. For those with a four-cylinder rear-wheel-drive INFINITI using a 7-speed automatic transmission, sudden and intermittent symptoms like harsh gear shifts or gear slippage may also occur. It is crucial for owners to recognize these symptoms early to prevent major complications and costly repairs, as well as to maintain regular transmission fluid changes and inspections to ensure smooth operation. Consulting a mechanic for proper diagnosis and timely repairs is advisable if experiencing these issues.
