Nissan Rogue split transmission oil cooler likely due to manufacturing defect on Nissan Rogue

Some Nissan Rogue owners report experiencing issues related to a split transmission oil cooler due to a manufacturing defect, which can lead to transmission problems such as difficulty shifting gears and slipping. Additionally, inadequate cooling may result in CVT overheating, causing shaking and shuddering, particularly in hot climates. Owners of early generation CVTs have noted design flaws and insufficient cooling systems that have led to overheating and mechanical failure, prompting Nissan to extend warranties for certain models to cover these CVT problems. Regular maintenance and proactive measures are advised to mitigate the risk of transmission issues, and using incorrect fluid or overfilling the CVT fluid can also result in symptoms that require attention according to NTB12-057.
