Symptoms of Failure

• Erratic shift timing and gear hunting: When the 4661.185.097 accessory wears, the transmission may struggle to find the correct gear, especially under load, leading to delayed or harsh engagements.
• Low hydraulic pressure warnings: A failing unit often causes internal leakage, triggering dashboard alerts for low line pressure or torque converter clutch slippage.
• Oil seepage around the valve body area: Degraded seals or cracks in this accessory can produce visible oil leaks near the HOUSING II interface, leaving puddles under the vehicle.
• Intermittent neutral or loss of drive: Severe wear may cause a complete loss of hydraulic circuit integrity, resulting in the transmission dropping into neutral without warning.
