Product Description
The ATS 303-121-2326 68RFE Accumulator Piston & Cover Kit is a critical upgrade for 2007.5+ 6.7L Cummins trucks looking to improve transmission reliability and shift performance. Designed to address common failure points in the factory 68RFE transmission, this kit strengthens the accumulator system for better clutch engagement and durability.
The factory accumulator piston and cover are known to wear and flex under increased pressure, especially in tuned or heavy towing applications. This ATS upgrade replaces those weak components with precision-machined, high-strength parts that maintain consistent hydraulic pressure and improve shift quality.
Ideal for both stock and performance builds, this kit helps extend transmission life, reduce slippage, and deliver more consistent shifting under load.
FAQ
Q: What does the accumulator piston and cover do?
A: It controls hydraulic pressure during gear shifts, helping ensure smooth and consistent clutch engagement inside the transmission.
Q: Why should I upgrade the factory components?
A: The factory parts can wear or fail under increased pressure, leading to poor shifting or transmission damage. This upgraded kit improves strength and reliability.
Q: Is this needed for tuned trucks?
A: Yes, it is highly recommended for tuned or towing applications where additional stress is placed on the transmission.
Q: Will this improve shifting?
A: Yes, it helps deliver firmer, more consistent shifts and reduces clutch slippage.
