The Corolla CVT truly has much less clutches than a standard transmission, as well as the belt shouldn't be slipping. Jack up still left front wheel, eliminate wheel & plastic panel guiding it so that you can see the fill bolt marked with “FE”. Loosen bolt. Set wheel back on. https://cvttoyota85061.daneblogger.com/33419199/cvt-toyota-can-be-fun-for-anyone
