Nissan Pathfinder oil and transmission leaks with RPM fluctuations over 3000 RPM on Nissan Pathfinder

Some Nissan Pathfinder owners report experiencing transmission fluid leaks, often due to hose problems, which can lead to slipping transmission and long-term damage if not addressed promptly. Additionally, engine oil leaks may occur from worn-out drain plugs, damaged gaskets, or component failures, making it crucial to identify and fix the source to prevent engine damage. Some owners also report RPM fluctuations over 3000 RPM, which may indicate underlying transmission or engine issues linked to these leaks. Furthermore, the radiator in some Pathfinders is known to develop cracks, potentially causing coolant to mix with transmission fluid and impairing lubrication. Repair costs for these issues can vary significantly, with fixing valve cover gaskets for oil leaks potentially costing around $600. Timely inspection and repairs are essential to prevent further damage to the vehicle.
