a stock 4L60E, sitting in traffic on a hot summer's day is known to see temperatures of 200+ degrees, so i assume it can protect past the 200 degree mark. i mean engine oils are made to work in environments of 210-230+ degrees and they don't break down. transmission fluids have tons more detergents and additives than engine oils, so i would imagine they could go to the 210-230 mark, too. i'm not 100% sure though. hopefully a sponsor will chime in.

Click the link in post #3. My TH400 runs at a cosistant 165* in cool weather and sees 185-190* in the heat. Temps go up at the track/ on the brake, and when I'm beatin' on it fairly steadily, but the fans seem to bring it right back down.
Keep it cool and it'll go a long time-

true ATF is cotton seed oil and is the same as used by Mcdonalds and other fast food fry units that run around 400 to 475 deg.
We have seen transmissions that run in the desert race series run at 315 to 325 deg for hours at a time,
they need time to cool down before the engine is stopped as the heat soak will boil out the fluid and cause an air lock.
but 150 to 235 is ok

i dont think it is the fluid temp that really burns it, more like the extreme heat found when clutches slip that burns the fluid, so if even if the fluid is at 200*F chances are the area where the slip occurred will be alot hotter, but not raise the overall temp by much...
