At least we try to answer questions posed here. I asked this question on Ford Powerstroke.org:
'99 PS Transmission Heat Issue
O.K., here's the deal. Had this truck for a couple of years now. Had a DP Tuner, dual exhaust and gages on the pillar which include a pyrometer, transmission temp and turbo boost installed when I bought it. It had 195K on the clock and had the tranny rebuilt at 130K. Bought it to tow our 25' 5th wheel. Transmission does just fine pulling the trailer at highway speeds even up some pretty steep Idaho grades. Runs about 180 degrees towing.
Once a year I pull this trailer up to hunting camp, uphill for about 9 miles at 25mph max. The first time, towards the top, the temps got to about 240 and I shut it down and let it cool before continuing. Changed the fluid when I got back to town but it didn't smell burnt.
I figured it wasn't getting enough air across the cooler at that speed so I added a tranny cooler with thermostatically controlled fan which was rated to 30K motorhome.The next year it made no difference. I shut it down earlier but it was on it's way to 240 again.
It's been a great truck other than this issue. No fluid leaks at all and uses about a Qt. of oil in 5K
So, I figure a line is plugged or bypass malfunctioning? Do I need to take it to a good tranny shop to have it diagnosed or do you guys have any tricks?
I forgot to mention that when I bought the truck, I serviced the tranny,replaced the filter and replaced the in-line filter.
This post sat there for 5 fucking days with no response. The forum has thousands of members. Then one guy posts that he has the same issue. 3 days later I get this:
When it's heating up a lot, is the TC unlocked?
If the bypass tube was messed up, you'd be heating up a lot all the time.

WTF? I missed the TC (torque converter, I'm guessin') switch on the dash? If it's not locked it's not going to be moving very well, is it? Maybe someone on our motorcycle forum could give a less innocuous or inane answer? Rant over, go back to your lives now.

i had an e40d in a ford diesel that i was sorry i ever put in a trans temp gage. yours is basically a "newer" e4od called the 4r100? mine did the same thing. they are well known for eating torque converters. i would prolly still have it if i didn't keep track of the temp.

Yep, but I don't appreciate any slipping so I can't see it being the TC.

Manual Transmissions rule.
You could try just adding a bigger, beastlier cooler. Take the Oil cooler off of an RX-7. Or a water-oil heat exchanger.
