If you are going to pull hills like this more than once, you definitely need to do an oil cooler add on, and possibly a trans cooler. Extended hot, high stress running will score your cams. This is why racers tend to use the 20/50wt oil.
If you are not using synthetic trans and hypoid lube....now is the time (Royal Purple, Mobil One, Red Dot are all good).[8)]
