In this riveting episode from the Donut channel, the intrepid team embarks on a quest to unravel the mystery behind the transmission failures plaguing their beloved WRX cars. With a hefty $330,000 investment in upgrades, including everything from tires to turbos, they were met with a cruel twist of fate when their transmissions went kaput. And it wasn't just one, but two separate failures, both involving the same model of transmission. Cue the finger-pointing and suspicions.
Our daring heroes waste no time in delving into the inner workings of these mechanical marvels. Armed with a transmission from a 350Z, they meticulously dissect it to shed light on its intricate mechanisms. The input shaft, the output shaft, and the counter shaft all play their part in transmitting power from the engine to the rear wheels. And let's not forget the shift forks, those cunning contraptions that engage the gears, allowing for seamless gear changes.
But alas, with great power comes great responsibility, and in this case, great stress on the transmission. The team uncovers the Achilles' heel of the WRX transmission: the third gear. Comparing it to the robust gears of the 350Z, it becomes painfully clear that the WRX gears are simply not up to the task of handling the increased horsepower. It's a design flaw, plain and simple.
As the team opens up the WRX transmissions, they are met with a disheartening sight. Teeth, or rather the lack thereof, are scattered about like casualties of a fierce battle. Third gear takes the brunt of the damage, leaving no doubt as to the source of the problem. The small, feeble gears of the WRX simply cannot withstand the forces unleashed upon them.
So what's the verdict? The team contemplates their options, pondering whether to replace the transmissions with STI 6-speeds, rebuild them with stock 5-speeds, or go all out with sequential transmissions. The decision hangs in the balance, and the fate of their beloved WRX cars hangs in the balance with it.
In the end, the Donut team emerges innocent, their hands clean of any wrongdoing. They have uncovered the truth behind the transmission failures, exposing the flawed design that couldn't handle the power unleashed upon it. It's a cautionary tale for all WRX enthusiasts out there, a reminder that not all upgrades are created equal. And as the dust settles, they bid farewell, leaving us with a lingering question: what's next for their trusty WRX cars?
