TR690GBDCA HIGH-TORQUE LINEARTRONIC CVT

The TR690GBDCA belongs to Subaru’s TR690 High-Torque Lineartronic continuously variable transmission family.

Subaru designed this transmission for higher-output applications such as the turbocharged WRX. Unlike a conventional automatic transmission with five or six fixed forward gears, the TR690 continuously changes its operating ratio according to vehicle speed, engine load, throttle position, and driving conditions.

The TR690 combines:

• Continuously variable ratio operation
• Torque converter
• High-torque CVT architecture
• Electronically controlled hydraulic system
• AWD transfer system
• Integrated front differential
• Manual simulated-shift operation
• Transmission cooler circuit

Subaru specifies Subaru High Torque CVT Oil for Lineartronic for the WRX automatic transmission and warns against substituting other fluids.

FA20DIT 2.0L TURBO APPLICATION

This transmission targets compatible Subaru WRX models equipped with the:

FA20DIT 2.0L Turbocharged Direct-Injection Boxer Engine

The FA20DIT uses:

• 2.0L displacement
• Horizontally opposed boxer layout
• Turbocharging
• Direct fuel injection
• Dual AVCS
• Timing-chain operation

The important drivetrain relationship is:

FA20DIT + TR690GBDCA + AWD + 4.11 Final Drive

Engine family alone does not guarantee interchangeability. The full transmission code and final-drive ratio should also match.
