Transmission Filter w/o Neck for Nissan RE4R03A 1990-Up

Maintain the efficiency and longevity of your Nissan or Infiniti vehicle's automatic transmission with this filter without neck.

Designed as a direct replacement for OEM part #31728-51X02, it fits RE4R03A (also known as JR403E or RG4R01A in related applications) 4-speed transmissions from 1990 onward, helping to resolve typical concerns like gear slippage, delayed or harsh shifts, failure to engage 3rd or overdrive, whining noises, overheating during towing or heavy loads, and reduced performance from contaminated fluid in high-mileage units. This durable all-metal filter effectively removes debris from the transmission fluid, supporting consistent flow, proper lubrication, and reduced friction on components such as clutches, bands, solenoids, and torque converters to prevent escalation into major failures like burnt bands or seal leaks.

Compatible with rear-wheel-drive and 4WD models including Nissan Patrol (Y60/Y61 with TB45, TD42, ZD30 engines), 300ZX Twin-Turbo (Z32 with VG30DETT), Frontier/Navara (D22 with 3.0L/3.2L), Cedric (Y33), Infiniti Q45 (with VH45DE V8), QX4 (3.3L/3.5L V6), and select Mazda Eunos Cosmo (20B-REW), often paired with V6, V8, or diesel powertrains. Ideal for routine fluid changes or rebuilds on vehicles showing signs of slow shifting, limp mode, or diagnostic codes related to pressure loss, this filter ensures reliable operation under daily driving, off-road, or demanding conditions, helping to extend the service life of your robust RE4R03A transmission and avoid expensive repairs.
