A worn or noisy gearbox can hold back an otherwise healthy RB25DET. The genuine Nissan Manual Transmission Assembly (part number 32010-AA520) is the factory five-speed unit specified for rear-wheel-drive Nissan Skyline R34 GT and GTT models with the RB25DET engine. Catalog applications cover ER34 25GTT cars with the five-speed manual and HI.2WD layout from the 1998–2002 production period, in both two-door and four-door body styles.
This is a pull-type clutch gearbox, the configuration used on late R34 RB25DET cars. It is the correct direct replacement when restoring or rebuilding an R34 GTT or GT rather than relying on a high-mileage used box of unknown history. Builders also use this assembly in other RWD Skyline and swap applications, though R33 GTS-T cars originally used a push-type clutch and require the appropriate conversion hardware if this later gearbox is fitted.
New Nissan transmissions are typically shipped with a small amount of preservative fluid to protect internal components during storage. That fluid is not service oil and must be drained and replaced with the correct GL-4 manual-transmission lubricant before the vehicle is driven. Professional installation, clutch inspection, and alignment are recommended to protect the new assembly.
At Terra Firma Automotive, we supply this genuine Nissan R34 GTT/GT Manual Transmission Assembly as the factory RWD solution for RB25DET owners who want a new OEM gearbox instead of a used unit. Choose Terra Firma Automotive for authentic Nissan drivetrain components that restore correct shift quality and reliability on the R34 platform.
