Genuine Nissan Transmission & Differential Fill Plug – R32 R33 R34 Skyline – 33312-33G0B
Maintain your Nissan drivetrain with a Genuine OEM Nissan Transmission & Differential Fill Plug – 33312-33G0B, designed for compatible Nissan manual transmissions and differential assemblies, including selected R32, R33 and R34 Skyline applications.
Whether you're performing a routine gearbox oil change, servicing your rear differential or replacing a damaged or rounded original plug, this genuine Nissan replacement provides factory-style fitment and quality.
Transmission and differential fill plugs are important service components that close the lubricant filling opening in the gearbox or differential housing. A correctly fitted plug helps retain the lubricant and prevent contamination from entering the assembly.
Over time, original fill plugs can become rounded, damaged, corroded or difficult to remove due to repeated servicing or incorrect tools. Replacing a worn plug with a genuine Nissan component helps restore the original service hardware and reduces the risk of future removal difficulties.
Manufactured to Nissan's original equipment specifications, this replacement plug is designed to provide the correct thread engagement and sealing interface for compatible factory applications.
Ideal for Skyline GT-R restorations, gearbox maintenance, differential servicing and general Nissan drivetrain repairs.
