I'm sure you use good fluid and change often, but you'll also see expansion/change of clearances internally as things heat up, seals can break down earlier, etc. Do you use any additives?
Street folks with turbo/supercharger kits will likely have less of a heat problem, unless maybe they are doing some really hardcore canyon driving. |
My last transmission failed on the 27th of december, 2020, on the 1st lap of the 2nd session of the day on a rather cold day!
I'd correlate the typical transmission failure more to tire grip and shock loading, rather than heat.
While this is highly anecdotal, I had just swapped in a stock torsen diff recently, due to selling my ATS LSD. My Drexler wasn't ready to put in yet. The track in question has rather large, painted berms, and my AIM data shows a lot of one tire fire when I get on the berms at WOT. This is the same type of load that shredded my OEM axles.
