Triple-Disc Torque Converters: Upgrading to a triple-disc converter triples the friction surface area. This ensures that when the converter locks up, the power goes to the ground instead of generating heat through slippage.
Billet Internal Shafts: For those pushing over 500 horsepower, billet steel input, intermediate, and output shafts are essential insurance against catastrophic mechanical failure. cummin tranny cum updated
The primary enemy of any Cummins transmission is heat. Because these engines produce peak torque at low RPMs, the internal components are under immense stress during acceleration and towing. Common failure points include: The primary enemy of any Cummins transmission is heat
If you are looking to update your transmission to match the power of your Cummins, there are several "must-have" modifications that experts recommend. 000 to 30
Stock Torque Converters: The single-disc factory converters often slip under heavy loads, leading to fluid contamination and eventual burnt clutches.Input Shafts: Under high horsepower or sudden "boosted" launches, the factory input shaft can snap like a toothpick.Valve Body Pressures: Low line pressure in stock units prevents the clutches from holding tightly, leading to premature wear and "flare" shifts. Essential Updates for Performance and Towing
No matter how many upgrades you install, maintenance remains king. With the high torque of a Cummins, transmission fluid breaks down faster than in a gasoline vehicle. Regularly changing your fluid and filters—every 20,000 to 30,000 miles if towing heavily—is the cheapest way to protect your investment.
