You will have a 6 speed. Use the towhaul button - forget about the 3rd gear advice.
Your rear end as mentioned above 3.08 or 3.42. Forget the reference to 3.73 - not available.
If 3.42 you should be fine if your tongue weight is not too high and you use a good WD system.
If 3.08 you will be well below requirements to tow that trailer.
9 3/4" rear with 3.73 was available on max tow trucks, but you'd have better luck finding a unicorn and the OP doesn't have that package.
OP - you will likely find that the truck will want to stay in fourth, depending on speed. If you stay around 60, it may hold fifth. More than that and it will go between 5th and 4th. Not a big deal, just drop into fourth if that happens.
Look in the glove box, there will be a sticker with a bunch of codes. GU4 - 3.08. GU6 - 3.42. KNP - Aux trans cooler.
