It's okay, your a newb for a reason. Never straight up tell someone to FLUSH their transmission fluid after that person has just stated that they have a crap load of miles. I know you are just trying to get your post count up, but c'mon.

Realized I never updated this thread with the outcome. Though a machine flush was done every 30k, the screen/filter was never cleaned nor replaced. I had my rear main seal replaced a few months back and asked my mechanic to look into the issue at the same time. From the moment I described it, he was certain it was a clogged screen. He changed it at the time of the rear main seal job - and the problem was resolved.
Long story short, the clogged screen/filter was not allowing for proper cooling.
When the temperature got hot enough, it downshifted as described above.
And just to add his opinion and methodology - Nissan transmissions require Nissan fluid, he swears by it.

I can't tell you how much it cost to change the RMS because I did mine myself. I did have an observation, though. In my experience, the half moon gaskets are almost always the main culprit to oil leaks at the engine for Nissans. I believe many people incorrectly diagnose the leak because of the proximity to the RMS which is, generically, a lot more familiar term to most people(including numerous mechanics). These gaskets can be changed by dropping the oil pans. The RMS, on the other hand, requires dropping the transmission and oil pans. Translation? It's expensive. I only did mine because I had the transmission out to R&R the clutch and reseal the upper and lower pans.
