    NNBS 4l70-e to 480-e swap.

    ok so i was haveing a fuel problem and on my way to test drive it the trans went out, a LOAD BOOM and then it sounded like i was shaking a coffee can full of change. so needless to say i am just gonna take the dive into a 4l80-e. According to my transmission guy he said the 4l60 is same thing as the 4l70-e. Is this true?I was thinking of a finishline trans until i saw the price now im kinda swaying toward a Monster trans seeing as thought its free shipping thats if Monster is any good. Last but not least does anyone sell a complete kit to do the swap?
