There is minimal valve-to-bore sealing at the line pressure to converter feed circuit, which allows critical apply fluid to leak past the valve spool and directly to exhaust\/sump. Typical cores show low vacuum at this critical TCC apply circuit and confirms the issue of poor valve-to-bore sealing. This minimal engagement of valve-to-bore by OE is further aggravated by continuous oscillation that causes casting bore wear.\u003c\/p\u003e\n\n\u003cp\u003eSonnax oversized TCC regulator and accumulator valve kit 44912-12K incorporates an extended spool for additional sealing support at the critical interface between the line pressure circuit and the TCC apply circuit. Also included in the kit is an oversized accumulator valve and a thicker accumulator spring retainer. The Sonnax valve kit is designed to salvage excessively worn pumps showing significant signs of wear. This valve kit can also be used as an enhancement to extend the life of the pump after repair.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eHardcoat anodized aluminum valves combat premature wear\u003c\/li\u003e\n\u003cli\u003eTCC Regulator valve has a lengthened critical spool for additional sealing area and wear prevention\u003c\/li\u003e\n\u003cli\u003eThicker accumulator spring retainer replaces thinner damaged OE accumulator spring retainer\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\u003cdiv class=\"part-accordion cb spaced-vertical\"\u003e\n\u003cp\u003e\u003cstrong\u003e\u003clabel for=\"components-panel\"\u003eContents:\u003c\/label\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"accordion-content\"\u003e\n\u003cul\u003e\n\u003cli\u003eTCC Regulator Valve\u003c\/li\u003e\n\u003cli\u003eAccumulator Valve\u003c\/li\u003e\n\u003cli\u003eAccumulator Spring Retainer\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eRequired Parts:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eReamer F-Tool Kit - Part No. \u003ca href=\"..\/i-30503036-reamer-f-tool-kit-for-44912-12k-92835-25k.html\"\u003eF-44912-TL12\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"col-4\"\u003e\n\u003cp\u003e\u003cstrong\u003eSymptoms:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConverter concerns\u003c\/li\u003e\n\u003cli\u003eLockup concerns\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\u003cdiv class=\"col-4\"\u003e\n\u003cp\u003e\u003cstrong\u003eCause:\u003c\/strong\u003e\u003c\/p\u003e\nMinimal valve-to-bore sealing at the line pressure to converter feed circuit allows critical apply fluid to leak past valve spool and directly to exhaust\/sump.\u003c\/div\u003e\n\u003cdiv class=\"col-4\"\u003e \u003c\/div\u003e\n\u003cdiv class=\"col-4 last\"\u003e\n\u003cp\u003e\u003cstrong\u003eCorrection:\u003c\/strong\u003e\u003c\/p\u003e\nRestore hydraulic control by reconditioning the bore and installing Sonnax oversized TCC regulator and accumulator valve kit.
