{"product_id":"pressure-regulator-valve-kit-104520-15k","title":"Pressure Regulator Valve Kit","description":"\n\u003cp\u003eGM 6L45, 6L50, 6L80 and 6L90 units may exhibit multiple line pressure and cooler\/converter\/lube flow problems due to excess wear in the pressure regulator bore. 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\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\u003cul\u003e\n\u003cli\u003eHardcoat anodized aluminum valve combats premature wear\u003c\/li\u003e\n\u003cli\u003eLengthened critical spools operate in non-worn portion of bore for added stability and wear prevention\u003c\/li\u003e\n\u003cli\u003eAnnular grooves help center valve in bore to reduce future side-load wear\u003c\/li\u003e\n\u003cli\u003eReplacement spring provides modest 5 psi line pressure increase\u003c\/li\u003e\n\u003cli\u003eNo pump drilling required\u003c\/li\u003e\n\u003cli\u003eDrop-in Zip Valve™ parts install quickly and easily\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003e\u003clabel for=\"notes-panel\"\u003eNote:\u003c\/label\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"accordion-content\"\u003e\n\u003cp\u003ePump must be removed to install kit.
