Enhancing Subaru Transmissions: Upgrades, Challenges, and Control

In a quest to unleash the full potential of their SuperX and Subaru WRX, the team at Donut embarked on a transmission upgrade journey. With $4,000 invested in the SuperX and a whopping $112,000 splurged on the WRX, the question loomed large - does a higher price tag equate to superior performance? The answer lay in the heart of the issue - weak gears, a common woe in Subaru transmissions due to the constraints of an all-wheel-drive system in a compact car. The solution? Upgrading to helical cut dog gears for third and fourth gear in a bid to bolster strength and reliability.

But the transformation didn't stop there. Enter the STI six-speed swap for the WRX, a game-changer brimming with promises of enhanced speed and resilience. The comprehensive upgrade package included not just the transmission but a myriad of peripherals - from the drive shaft to the clutch, flywheel, axles, shifter, and linkage. A meticulous approach was adopted, ensuring every component aligned seamlessly to create a powerhouse on wheels. The team's dedication to saving costs without compromising on quality shone through, a testament to their passion for the craft.

As the pieces of the puzzle fell into place, challenges emerged - aftermarket parts clashed with OEM counterparts, demanding finesse and expertise to harmonize the system. The expertise of a seasoned professional, Ron, proved invaluable in navigating the intricacies of transmission assembly. Amidst the trials and tribulations, a stroke of genius manifested in the form of a DCCD controller, offering unparalleled control over power distribution between the front and rear wheels. The team's perseverance in overcoming setbacks, from gear interference to clearance modifications, underscored their unwavering commitment to pushing boundaries and redefining performance standards.
