The computer varies the pulse width modulation of the TCC PWM solenoid, which regulates the apply pressure of the lock-up clutch. Because of the constant PWM solenoid induced oscillation, over time, excessive wear of the bore occurs. As a result, the computer loses the ability to control the lock-up clutch apply rate and slip rate properly due to the loss of TCC apply pressure.\u003cbr\u003eFeatures and benefits:\u003c\/p\u003e\n\u003cp\u003eThis TransGo drop-in precision ground USA-made hardened steel TCC valve is designed to restore the hydraulic integrity of the circuit without the need to machine the bore. It has re-positioned longer lands so that both ends of the valves have better support which promotes less wear. Additionally, the valve has a machined groove cut where a scarf cut sealing ring is fitted. As a result, this new valve is a fix even with substantial bore wear. Two different springs are provided providing the option for either stock or slightly elevated TCC pressure and slightly firmer TCC apply.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eOptional ON\/OFF lockup in 2 easy steps for high power hot rods or overloaded trucks:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eConvert lockup into an ON\/OFF system for improved holding with a shorter apply time for severe duty applications.\u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003eCorrects\/Prevents\/Reduces:\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eTCC slip\u003c\/li\u003e\n\u003cli\u003eCodes 39, 68, P0741 and P0894\u003c\/li\u003e\n\u003cli\u003eDamaged torque converter due to slip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eDrop-in precision ground USA-made steel valve\u003c\/li\u003e\n\u003cli\u003eScarf-cut sealing ring\u003c\/li\u003e\n\u003cli\u003eOrange spring for stock lock-up pressure and feel\u003c\/li\u003e\n\u003cli\u003eGreen spring for slightly elevated TCC pressure and slightly firmer lock-up apply\u003c\/li\u003e\n\u003cli\u003eO-ring (for sizing only)\u003c\/li\u003e\n\u003cli\u003e0.125” drill bit for optional ON\/OFF lock-up\u003c\/li\u003e\n\u003cli\u003e0.063” drill bit for optional ON\/OFF lock-up\u003c\/li\u003e\n\u003cli\u003eRivet for optional ON\/OFF lock-up\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"TransGo","offers":[{"title":"Default Title","offer_id":47978270392542,"sku":"A34741CK","price":22.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/5464\/5470\/files\/A34741CK_1.jpg?v=1773326167","url":"https:\/\/transmissioncenter.net\/products\/4l80e-4l85e-tcc-regulator-lock-up-valve-kit-transgo-4l80e-tcc","provider":"Transmission Center","version":"1.0","type":"link"}
