After driving on the highway for a while, I started to mess with the different gauges on the dash....I noticed the transmission temp was anywhere from 208 - 210. Is this normal? Seems hot for not towing/hauling anything. Anyone else have this same experience?

I just got in this afternoon from western NC to south Ga ( about 425 miles) and checked my trans temp through out the trip and it read between 188 - 198. The outside temp today was 102 degrees....Yeeeooowww!!!

Have any of you installed a front grill guard which would ruduce air flow and increase temps?

I noticed this on my truck soon after I bought it. After normal driving for 15 minutes or so the transmission temp would be 91-93 C (200 F). I thought that was pretty warm for an unloaded truck and kept an eye on it for awhile but it didn't get any higher than that. This past summer I pulled the holiday trailer through the mountains and saw it as high as 96 C (205 F). I normally have a grill installed to protect the inter cooler but remove it when pulling a trailer. I've stopped worrying about the transmission temp as it has never caused a problem and I'm approaching 60,000 km on my truck. One thing that I have noticed regarding the transmission temp is that the truck will not get it's best fuel mileage until the temps are into the 80+ C range. The difference is quite significant 2-3 litres/100 kms. 2 1/2 -3 mpg.

The lock up torque converter is temp controlled, maybe you're feeling that until it warms up enough to lock up. My truck runs at higher rpm in 6th gear also until it warms up.This is normal unless its severe slipage

The lockup converter is not allowed to engage until the trans temp is around 104 degrees F.  If you watch the trans temp on a cold start and go and drive the truck, you will feel the converter lock once the gauge is reading that temp.  That is to prevent customer "whine" due to not understanding how all the systems tie together.  If the engine and trans are not at proper temps you can have strange noises, and drivability issues, and the possibility of misfires under certain loads.  It also allows the fluid to be at enough temp to do it's job properly.  That is why it is set up the way it is, to prevent complaints and wasting technitions time at the dealer for something that is not an issue.  Typically I will see my engine coolant temp around 192-194F before the trans hits 104F and allows lockup.  The temps of the trans under load, or unloaded on my truck have never been over 210F.  Unloaded it is normal to see 195-200F, and a little higher with a load.  I had discussed that issue with the higher trans temps with a buddy of mine that works at a Ford dealer, and he said it is normal.  My 2003 F-350 with a 3 clutch converter and Amsoil wouldn't even hit 170F with a 100hp tune, and 12,000 lb behind it on a 95F day.  His 2012 F-350 with the 6.7 diesel runs the same temps on the trans as the F-150 trucks.  The trans cooler is mounted in front of the radiator, and is above the CAC, so having the grill cover on the bottom to protect the CAC will in no way affect the trans cooler.  If you have the main upper grill covered, well then you can have an issue.
