Hot trans tunnel
2000 F250, 7.3, 4x4, ZF6, 285k miles
I was driving my pickup with a camper on the highway the other day and I could feel heat in the trans tunnel, outside temp was probably around 90. I don't remember feeling it in the past even with my camper and towing my car trailer. Pretty much just do that in the summer so I would think I'd have noticed it before if it was ongoing.
With an IR thermometer, it was registering 160ish at the highest right on the shift boot bezel.
I don't have a pyrometer so unsure on EGTs but I was monitoring EOTs and they we're staying 200-210 range for the most part. Seems to me that would rule out the EGTs causing the extra heat?
I didn't crawl under there to check cooler lines, wasn't aware about those until I started searching online about the problem. I was already planning on changing the fluid as it's been about 60k.
What an easy way to check if the cooler is plugged or the pump is shot?
Is there any other cheaper and easier explanation to the heat that I'm not thinking about?

A lot of heat is in that area. That's where the downpipe is, the up-pipes and the turbo is right above it. With the fan kicked on, the heat is forced through the engine compartment and down. 160 on the inside seems a little hot, but its only 70 degrees above ambient and I bet you might have a little leakage of air through the boot area. Mine does.
