Sorry - I just noticed this was answered farther down the page. Never mind.

I am sure this is pretty dumb question, but how does one know which auto tranny is in the truck? Can you tell from the VIN? Oh, it's a 2002 SC XLT Sport 4x4 with the 5.4L and 3.55 LS rear axle (6,500# GVWR).

 

Got this from www.fordf150.com

Here is an example of the vehicle sticker you wilfind in the driver's side door jamb:



Here is what each of the items are (corresponding numbers):

Exterior Paint Code
