This plunger valve positions the TCC modulator valve, which feeds line to the apply circuit, which controls slip rate. Wear of the sleeve will allow the TCC slip rate to continue to rise, and could prevent full lockup. The Sonnax assemblies restore hydraulic integrity to the TCC solenoid circuit with precisely toleranced parts. The elevated modulated pressure will not raise apply pressure to the point of TCC piston fatigue, and will result in firmer TCC apply and reduced slip RPM in heavier use applications. Increased ratio provides a firmer and quicker lockup feel. OE stock ratio restores original lockup feel. Precisely toleranced parts restore hydraulic integrity. Hard-coat anodized aluminum valves resists wear. High-grade aluminum sleeves are extremely wear-resistant.
