Nissan 3137580X01 — Automatic Transmission Oil Pump Seal
Overview
Automatic transmission oil pump seal Nissan 3137580X01 seals the front oil pump housing within the automatic gearbox assembly, preventing automatic transmission fluid (ATF) leaks at the pump interface. Manufactured from heat-resistant fluororubber (FKM), this O-ring withstands continuous thermal loads up to +180 °C and resists chemical degradation from synthetic ATF fluids. Key technical specifications include an inner diameter of 112 mm, outer diameter of 118 mm, and a cross-section thickness of 3 mm. OEM reference numbers include 31375-80X01 and 3137580X01. The seal retains elasticity across temperatures from -40 °C to +180 °C, maintaining line pressure inside the hydraulic circuit. Exact factory dimensions allow precise seating into the pump groove without sealant.
This transmission oil pump O-ring fits Nissan Pathfinder R51 2.5 dCi / 4.0 models 2005–2014, Nissan Navara D40 2.5 dCi 2005–2015, Nissan Patrol Y61 3.0 DDi / 4.8 2002–2013, 350Z Z33 3.5 2003–2009, Infiniti FX35 S50, FX45 S50, G35 V35, and QX56 JA60 equipped with the Jatco RE5R05A 5-speed automatic transmission. Replacement is required when ATF fluid leaks appear around the bellhousing area, during gearbox overhaul, or when replacing the front oil pump assembly. Prompt replacement prevents pressure drop and fluid starvation in the clutch packs and valve body.
