Deterioration at the balance spool end allows critical fluid loss, resulting in high line pressure, harsh shifts and overheating due to reduced cooler\/converter flow. Wear at the outboard spool robs converter feed pressure and lowers line pressure, resulting in soft shifts and burnt clutches.\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003eInstalling Sonnax pressure regulator valve kit 104520-15K restores the hydraulic integrity of these circuits for proper line pressure control in all ranges. A new pressure regulator valve outer spring is also included to replace weakened original springs and provides a modest 5 psi increase across the pressure curve.\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eHardcoat anodized aluminum valve combats premature wear\u003c\/li\u003e\n\n\u003cli\u003eLengthened critical spools operate in non-worn portion of bore for added stability and wear prevention\u003c\/li\u003e\n\n\u003cli\u003eAnnular grooves help center valve in bore to reduce future side-load wear\u003c\/li\u003e\n\n\u003cli\u003eReplacement spring provides modest 5 psi line pressure increase\u003c\/li\u003e\n\n\u003cli\u003eNo pump drilling required\u003c\/li\u003e\n\n\u003cli\u003eDrop-in Zip Valve™ parts install quickly and easily\u003c\/li\u003e\n\n\u003c\/ul\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e\u003clabel for=\"notes-panel\"\u003eNote:\u003c\/label\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cdiv class=\"accordion-content\"\u003e\n\n\u003cp\u003ePump must be removed to install kit.
