High-performance applications often require an alternate source for line pressure regulation because the vehicle is equipped with a non-reprogrammable electronic control module. This kit makes a nice alternative for a more reliable and tunable pressure control system.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures and benefits:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThis TransGo internal modulator kit provides tunable line pressure regulation with a vacuum modulator instead of the vehicle PCM controlling the EPC solenoid. The kit includes everything needed to add the internal modulator system with the oil pan off the transmission. From the outside of the transmission you will need to connect it to an intake manifold vacuum source, however hardware is not provided for this. In addition, it comes with an oil pan based resistor to pacify the control module for the missing EPC solenoid in applications where the computer will still manage the gear changes.\u003c\/p\u003e\n\u003cp\u003eThe kit requires the OE reusable pan gasket GM part # 8677743 for adequate clearance.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli style=\"list-style-type: none;\"\u003e\n\u003cul\u003e\n\u003cli\u003ePressure regulator valve spring and snap ring\u003c\/li\u003e\n\u003cli\u003eBrass fitting\u003c\/li\u003e\n\u003cli\u003eVacuum modulator, pin, valve and bushing\u003c\/li\u003e\n\u003cli\u003eHold down bracket\u003c\/li\u003e\n\u003cli\u003eElbow vacuum hose and spring\u003c\/li\u003e\n\u003cli\u003e(4) Short zip ties\u003c\/li\u003e\n\u003cli\u003e(5) Long zip ties\u003c\/li\u003e\n\u003cli\u003eVacuum tee\u003c\/li\u003e\n\u003cli\u003eResistor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"TransGo","offers":[{"title":"Default Title","offer_id":47967344132318,"sku":"A34431E","price":123.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/5464\/5470\/files\/A34431E_1.jpg?v=1773167398","url":"https:\/\/transmissioncenter.net\/products\/4l80e-4l85e-vacuum-modulator-kit-transgo-48-mod","provider":"Transmission Center","version":"1.0","type":"link"}
