Thank you for all of your replies as well as the in-depth research. You guys are great. When installing the larger trans. cooler and gauge I also had them flush completely the transmission, put in a new filter and put in BG brand synthetic fluid. The old fluid (about 12,000 miles old) was a little off color which prompted me to make improvements during this vacation. Once I am home I may go to a deeper pan as well. All good suggestions.
I have had the 6.0 cooler on mine nearly as long as I have been towing heavy about 8 years early 99 7.3. 185-190 on long mountain grades in 90 plus degrees. 240 IMO is going to get that 4R100 eventually. Have never read where that deeper pan did anything but give you more fluid to cool. It is not the answer, a 6.0 31 row cooler is all you need. Not sure what you mean by installing a larger cooler, if it is a 6.0 31 row, you shouldn't see over 200, with mine towing 13K, like I said ,185-190 is the extreme. You may have a problem that a cooler won't fix.
