I have a 2000 7.3l F250 and have had the 6.0 oil cooler installed. You do not want to be at 240 for very long. Check the smell of your tranny fluid on the dipstick. If it smells burned, you have been too hot. I also have the BTS transmission installed and I do not see temps above 160 anymore. I run Scheffers synthetic fluid in the truck as well.
X-2. I have the John Wood Towmaster tranny with the 6.0 tranny cooler.
The stock 4R100 tranny is the weak link if you are towing heavy.
I agree they are the weak link, but IMO the weak link was the cooling, and not so much the tranny. I am still running the stock tranny in my early 99. As I said been towing heavy for the past eight years, but have had the 6.0 cooler. The inadequate cooling killed a lot of the 4R100's before the 6.0 cooler even showed up. If I had been towing heavy with mine early on I probably would of burnt it up also. There is nothing on my truck before I installed the temperature gauge to even tell me if I was overheating. Many were probably overheated and ruined before they knew it.
