{"product_id":"pressure-switch-rebuild-kit","title":"Pressure Switch Rebuild Kit","description":"\n\u003cdiv class=\"spaced-vertical\"\u003e\n\u003cp\u003eListed GM 6-speed transmissions often set various trouble codes related to failures of fluid pressure switches that are internal to the transmission electro-hydraulic control module (TEHCM). These codes may be accompanied by TCC apply problems or shift irregularities such as slipping, flares, harsh application, and bind-ups. As time goes by, the laminated portions of the pressure switches can breach, preventing normal switch operation. If more than one switch breaks down, failsafe mode can be triggered. Since switches cannot be obtained through OE channels, replacement of the TEHCM was the only previous remedy available.\u003c\/p\u003e\n\n\u003cp\u003eIt is no longer necessary to replace the expensive TEHCM assembly to rectify this concern. Installing Sonnax pressure switch rebuild kit 124740-70K restores normal switch operation, eliminating codes and providing renewed shift performance in all ranges.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eAllows salvage of expensive TEHCM\u003c\/li\u003e\n\u003cli\u003eKit includes enough discs and seals to rebuild 10 TEHCM units\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=\"notes-panel\"\u003eNote:\u003c\/label\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"accordion-content\"\u003e\n\u003cp\u003eBefore installing kit, test switches to verify proper electrical operation.
