Symptoms of Failure

• Erratic gear engagement and slipping under load: When the 4644.153.440 clutch wears, the transmission may hesitate or fail to hold a gear, especially during heavy hauling or uphill operation.
• Oil contamination and metallic debris in the fluid: Friction material degradation from this clutch introduces fine metal particles into the hydraulic circuit, often visible during routine oil changes.
• Delayed or harsh shifting between forward and reverse: A failing clutch causes noticeable lag or abrupt engagement, often accompanied by a shuddering sensation through the driveline.
• Overheating and burnt odor from the transmission: Slipping clutches generate excessive heat, leading to fluid breakdown and a distinct burnt smell emanating from the vent or dipstick.
