Hello All: I just purchased a 2003 F-150 4.6, 4r70w, 355 LS Extended cab XLT. How do I tell if I have the tow package??

 

Transmission oil cooler. (for auto trans). 7 pin connector (although these are easily added later).

 

factory reciever hitch
fuse block pre-wired for trailer brakes and relays

 

Trailer Towing package includes a heavy-duty alternator, HD battery, super-cooling package, auxiliary trans cooler, factory hitch, factory 7-pin connector on the bumper.

Look in front of your radiator. If there is a cooling device on the passenger side that's the aux trans cooler. That's a good sign you have the tow package along with all the other stuff listed.

 

I could be wrong, but didn't the aux trans cooler come as a part of the super-cooling package? (which was, of course, a part of the trailer towing package) If so, an aux. trans cooler is not necessarily an indicator of the TT package.... it's all a little fuzzy these days.

Another package that you may have is the Heavy duty payload package which is identical to the tow package minus the reciever and 7 way receptical. Even though its not the tow package it does still have all the fuses and relays for brake controller. I
