NISSAN 32709-58S00 Speed Sensor Oil Seal

The genuine NISSAN 32709-58S00 (Speed Sensor Oil Seal / SEAL-OIL) is a premium quality, original component designed to ensure proper sealing between the speed sensor and the transmission housing. Its function is to prevent gear oil or transmission fluid leaks at the sensor mounting point while protecting the internal mechanism of the transmission from external contaminants, dust, and moisture.

Technical Characteristics and Material Composition

Although specific physical dimensions are not individually listed, genuine Nissan oil seals are manufactured to the strictest OEM standards:

• Material: High-grade, oil- and heat-resistant elastomer (typically NBR or FKM/Viton) that resists the chemical properties of modern transmission lubricants and elevated operating temperatures.
• Design: Precision sealing lip design for optimal fitment and minimal friction loss.
• Durability: Excellent wear resistance and elasticity retention over an extended service life, even under extreme temperature fluctuations.

Function of the Oil Seal and Symptoms of Failure

The speed sensor oil seal plays a critical role in maintaining proper transmission lubrication. Seal aging, wear, or damage can result in the following issues:

• Oil Leaks: Oil spots appearing under the vehicle, specifically around the transmission housing.
• Sensor Contamination: Leaking oil combined with accumulated dust can disrupt speed sensor operation, causing inaccurate speedometer readings or triggering diagnostic trouble codes (service indicator light).
• Low Transmission Fluid Level: Continuous fluid loss reduces lubrication levels, potentially leading to premature transmission wear or severe mechanical damage.

Genuine Nissan components guarantee precise fitment and reliable performance, preventing leaks that may result from dimensional inaccuracies in aftermarket alternatives.
