Product Description
Built 6R140 Performance and Reliability with ATS Stage 2
The ATS 309-924-3368 Stage 2 6R140 Transmission Package is engineered for 2011–2014 Ford Super Duty 6.7L Power Stroke 4WD trucks that demand more strength, reliability, and performance than the factory transmission can deliver. Designed for towing, heavy-duty use, and increased horsepower applications, this ATS Stage 2 package provides the upgrades needed to handle real-world diesel stress.
The factory 6R140 transmission is strong, but under heavy loads, tuning, or aggressive towing conditions, internal wear and clutch slippage can become an issue. ATS addresses these weaknesses with a fully upgraded Stage 2 transmission package that improves clutch holding capacity, increases durability, and enhances overall transmission performance.
Whether you're towing heavy loads daily or running added power, this ATS package delivers the confidence and reliability your truck needs.
Key Features:
- Stage 2 upgraded 6R140 transmission package
