Rostra variable bleed solenoids for Ford Gen. 2 6F35 transmissions feature an improved design that delivers OE performance with increased durability. For greater long-term reliability, the Rostra design has no permanent magnet like the OE for less drift over time, plus uses a stainless-steel internal seat, rather than a plastic one. Each solenoid is tested to meet four different pressure gates, as well as multiple pressure targets, to ensure quick vehicle adaptation will occur. See datasheet for testing details.

• Improved sensitivity and reduced hysteresis over the OE design
• Accurate pressure control to within tenths of a psi allows for seamless torque transfer between active clutches
• Improved Rostra design increases reliability and durability
