JDM Subaru WRX TY754VBBAA 5-Speed with Matching 4.44 LSD

The WRX 5-speed takes a beating, especially behind a turbo engine with sticky tires. When yours finally grinds, pops out of gear or whines, this JDM Subaru TY754VBBAA transmission is a ready-made fix. It’s the 5-speed manual AWD gearbox for the 2002–2004 Impreza WRX turbo, with a 4.44 final drive. In addition, it comes with the matching 4.44 limited-slip rear differential. As a result, you get a complete, ratio-matched drivetrain package.

Why the Matching LSD Matters

On an all-wheel-drive Subaru, the front and rear final drive ratios must match. Otherwise, the drivetrain binds and the center differential wears out fast. Because this package includes a 4.44 rear diff, the ratios already line up. Moreover, the limited-slip rear diff improves traction out of corners and on wet or snowy roads.

Signs Your WRX 5-Speed Is Failing

• Grinding when shifting, especially into 2nd or 3rd
• Popping out of gear under load
• A whine or howl that changes with speed
• Clunking or binding when turning

Fitment

• 2002–2004 Subaru Impreza WRX turbo, 5-speed manual (bugeye and blobeye)
• Other 2002–2007 WRX builds can also use this package, with the correct clutch parts and the included 4.44 rear diff
• Not for the STI, which uses a 6-speed

To confirm, match the code on your current transmission with TY754VBBAA, or send us your VIN. For background, see the second-generation Subaru Impreza overview.

Why Buy JDM?

JDM drivetrain parts often come from lower-mileage cars, thanks to Japan’s strict shaken inspection rules. In addition, a used JDM 5-speed costs far less than a rebuilt unit.

Installation Tips

1. Fill the transmission and rear diff with fresh gear oil of the correct grade.
2. Use the correct clutch kit, release bearing and fork for this transmission, and resurface or replace the flywheel.
3. Inspect the transmission and rear diff mounts.
4. Check the axles and CV boots, and replace any that are worn or torn.
