Its a 47re. Thats what I have with 3.55's, personally I feel that 35's are a little big, I ran 33.5" tires and those are about as big as I would run towing with that trans and gear set up. You just put a lot of stress on the transmission if you ever try to use O/D or you have to wind it out in 3rd if you want to break 50mph and your milage suffers greatly for it. If you upgrade your trans and change the valvebody for running tires that size, you could probably get away with it without, being too hard on your stuff.
