So, I wonder if anyone has actually measured the temperature of the transmission oil in a FR-S/BRZ, under or just after, an extended load (like a heavy track session) ...??
Anyone out there .. ??

Air is an awesome insulator. There are a few inches of rapidly moving air between the case and the tunnel to spirit away all that heat.
The temp question. I'd ask Velox. They measure everything.
Element added a high capacity transmission oil cooler after they started burning up transmissions, but they are very protective of their information.
...I don't suppose those tractors had transmission oil coolers...?
That, and you said they did get warm on the outside... which takes quite a bit of energy with a thick-walled nodular iron case.
As for me, I haven't burned up a transmission... yet. If I do, I suppose I'll have to start measuring.
