Transmission failure from coolant

Recently bought a 2005 frontier SE 4x4 6spd, so far been very happy with it. But i have been reading around and I am worried about transmission failure from coolant getting into transmission fluid. Everything i have read has referred to automatic transmissions, and i havent seen any mention either way about manual transmissions. Not sure if i should be worried and working on some fix, or enjoying my frontier. Thanks

Just found this: so i assume that applies to the frontier 6spd manual as well and they are not at risk of this contamination

I have an 08 Frontier Auto with 44k miles on it. I am curious...
1. All years have this issue?
2. Is there a certain age (assuming fluids were changed properly and when needed), that this failure occurs?

I personally would like to leave mine connected, as it can get cold here and having it able to be heated is nice. And also, when I go on long trips, it is nice to have it cooled.

I am thinking I may just buy a new radiator every 60k miles or so and keep it hooked up as intended?
