Your comments and write-ups on the 4R-100 transmission are interesting, informative & enlightening. Printed a lot of it out for future reference ... but now the future is here.
Just completed a 6000 mile trip to East Coast & back towing our 25' travel trailer. It was fun & good except for the 3 tire blowouts on the trailer the last 2 days of the trip. 5 new tires corrected that problem.
The last 50 miles had me on the edge of my seat because of EGTs (1200 degrees for 2-3 minutes) and TRANSMISSION temps. (220 degrees for maybe 10 minutes) Pulling the mountain out of Vegas to Pahrump was the longest, hard pull of the whole trip & it was 112 degrees outside!
The FIX: Run my programmer in the Tow-Safe mode instead of Performance and upgrade to the 26 row 6.0 trans cooler. Ordered mine yesterday from AutoNation Ford (formerly Tousley) ... They're great! I mistakenly ordered the 31 row but Mike quickly changed to the 5C3Z-7A095-CA unit before the part was shipped.
I'm going by "woodnthings8's" excellent write-up. My problem is: Where to get the 1/2" transmission fluid rated hose at some reasonable price. O'Reillys here in Pahrump will order it for me @ $15 per foot. I know it's precious, but it's not gold.

Any suggestions?? I'd appreciate it.
