Drive off the lot in a 2007 Titan 4wd with just over 105,000 miles on Monday of this week. Everything looked good, felt good, no signs of abuse or leakage anywhere, shifted fine. Sharp looking truck overall and I got it at a great price. All is good I thought. Drove it home about 1.5 hrs away and park it in the driveway. Tuesday morning I come out to find something has been leaking onto the driveway. Looks like tranny fluid. Long story short, my new to me Titan is now in the transmission shop awaiting diagnosis. To say I'm pissed is an understatement. Turns out I may have coolant in the transmission. I checked the fluid before it was towed to the shop and all seemed fine. Hopefully the transmission is ok. I will find out tomorrow morning.
I can't even believe this happened...

That sucks my friend. It is a very common problem. It can be absolutely detrimental to the tranny if not identified very quickly. I'd say as long as it was shifting fine all the way home that hopefully no damage was done and just a good flush and tranny line fix will have you on your way to enjoying your new to you truck.

Was it leaking from the radiator? Those clamps they use on the lines connecting to the cooler side of the radiator leak pretty badly.
I had an issue over 100k ago where it leaked, was not locking up at 1st press of the accelerator from a stop (low fluid symptom) and I made the fix, added fluid and it has had no issues since. The Jatco tranny used in these trucks are robust and can take a little fluid leak as long as you get it resolved as quickly as you have.

Leaking from the front near the radiator or from the tranny itself?
Well, what I thought was tranny fluid turned out to be power steering fluid. Fixed the ps leak and did the tranny cooler radiator bypass just because of all the horror stories I've read about on here. Changed the trans fluid also. I get the truck home yesterday afternoon and notice another leak that looks to be coming from the rear differential. Looks like the cover gasket or maybe the pinion seal. Holy freaking crap! I'm afraid to drive the thing for fear of where the next leak is gonna spring up. My 01 f150 with near 200,000 miles looks bulletproof compared to this truck so far. Oh well, guess it gives me something to do on the weekends....

My 01 F150 was a piece, all sorts of problems before I traded it at 95k, My sons 04 is the same, he only has 45 K on it and it has been in the shop multiple times.

How common is this? I'm somewhere between 140 and 150K miles. No signs of leaks or loosing coolant but I'd like to avoid any risk to the tranny.

It's not common at all. The transmissions in the Titan are pretty tough actually. You have to watch out for the OEM transmission cooler line wearing out around 100k, I think it is. Just change the tranny fluid every 30-50k, depending if you drive it everyday or not and you will be fine. The motor will go before the transmission as long as the fluids are swapped within a reasonable amount of miles.

Plastic radiators are in all cars now so over 100K miles cracks happen and unfortunately the transmission lines run through the area the Titan radiator cracks. This floods the tranny with coolant and destroys the $4k tranny. I suggest doing the bypass mod or risk that nightmare...
Have they changed the design or is this true for all 04-15 Titans? I hate to risk my transmission but I don't want to lose the cooling feature for the transmission either. It gets hot in Texas.
I installed the stillen all aluminum rad at first sign of the hunk of junk that is the Oem rad. Drain chock got brittle and broke off, literally just crumbled in my hand. Stillen was on sale so less that $200 later I had something I didn't have to worry about anymore and it looks great.

Ok, thanks guys for the input. I'll start with a bypass mod and then maybe add an external heat exchanger if I can find a bulletproof one.
