Transmission cooler stock or optional on an '04 Titan?

I posted this question under another thread, but started this post to get more exposure to my question with more detail.

Being new to Titans, having just bought a 2004 LE, mine appears to have two radiators with a fan both inside and outside. Lines run from the tranny up to the radiator(s) and back to the tranny. Did the 04 come with a trans cooler as standard or an option?

I have already established that i have the 3.36 gears for towing (engine turns 2000 rpms at 70 mph), but have no tranny temp gauge. I do not have the off road package that has the 3.36 gears, as i have 18" wheels and no skid plate. I was planning to buy a tranny cooler, but looked under the hood and see the two radiators, or at least it appears to be two of them. fron beneath the truck, i can put my fingers up between the two radiator cores. Else, why would there be two fans unless there are two radiators there?

You have a line going through the one and only radiator plus a small external cooler sandwiched between it and your ac condenser......which is the reason for having an extra fan.
Are you sure it's a tow package?
I would expect a Tow Mode switch also.
My non big tow has that.
Speed and rpm will always be in sync with each other, regardless of wheel and tire.
Actual speed is what can vary.

It sounds like you definitely have a tow package.
*Lower gear ratio, the physical size of the gear doesn't change*
You mean the size of the ring gear, because the pinion size will vary....3.36:1 uses a smaller pinion.
Or look for an ID tag on the axle, look up the VIN etc.

You'll have to turn the drive shaft and watch the tire, because turning the tire will only turn the other tire backwards.
