In Ford 6R140 transmissions, bore wear at the low/reverse regulator valve is a common source of pressure loss, leading to delayed Reverse engagement and clutch failure. Reconditioning the bore and installing the Sonnax oversized low/reverse regulator valve kit restores proper valve body function and hydraulic control. Engineered with annular grooves and a hardcoat anodized finish, the valve combats future wear and improves long-term durability.
