I test drove an 2004 cc with offroad package. I am not there right now to look at it and Im trying to figure out what gears it has. It does not have the trans temp guage. So Im guessing that means it does not have the big tow package. Does big tow package also incorporate an external trans cooler or is that found on all titans? The more searching I did here the more conflicting info I found. I can get the VIN if that will tell. I want to make sure I have the 3.36 gears and the external trans cooler because I will be towing regularly.
