Product Description
The ATS 303-010-4290 Allison Pressure Regulator Valve is a high-performance upgrade designed for 2004-2005 6.6L Duramax trucks equipped with the Allison transmission. This upgraded regulator valve improves transmission line pressure control, resulting in firmer shifts, better clutch engagement, and increased transmission durability.
The factory pressure regulator valve can wear over time, leading to inconsistent line pressure, slipping, and reduced transmission performance. ATS addresses this issue with a precision-engineered replacement that restores proper hydraulic control and enhances overall transmission operation.
This upgrade is ideal for both stock and performance applications, especially for trucks used in towing or tuned for additional power where consistent transmission pressure is critical.
