Transmission cooler
Has anyone installed a secondary trans cooler on the X? I need extra cooling and would appreciate any tips on manufacturers and installation. Thanks.

I don't know much about the V-10's, but one of the common upgrades for us 7.3L PSD owners is to swap out our tranny coolers for a 6.0L PSD tranny cooler.
Is that an option for you?

My 2002 V-10 has one of the largest coolers I have ever seen on a non-commercial vehicle, I wonder if they used different coolers on earlier models. If you can get one of the big coolers it might not be much more than one of the big aftermarket coolers.

Agreed wholeheartedly and would add; I believe the gauge should always come first no matter the load size honestly. If you're gonna tow, you gotta know your temps.

I installed an Auto Meter trans temp guage with the sender in the test port on the side of the case. I mentioned it in another thread that I was running temps up to 225 degrees (2nd gear, very long climbs with a 10K lb trailer) and was wondering if others thought that was too high. My own research says that is a very borderline temp that doesn't acutally cause mechanical failure on its own but does degrade the fluid and causes a need for replacement at 10,000 mile intervals.
I'm hoping that by adding another cooler to the system, I can drop the max temps down to about 190 - 200 degrees. I'm just wondering if this approach will actually work. Without the trailer, I never get above 180 degrees even if the vehicle is loaded with kids and gear. It's the trailer that really heats up the trans.

If I were going to add an "additional" cooler, i would go with a Stacked Plate with LPD (low preesure drop). This would allow the fluid to by-pass the cooler when it was too cold - letting the fliud warm up to operational temp.
You could also look at a larger/deeper tranny pan.
If your tranny is running that hot, have you considered installing diff temp guages?

Nice graphic. It seems that the break-points for "too hot" are all over the place. This info says 220 degree temperature is good for 50K miles while other sites say it's good for only 10K miles. I wish Ford had some engineering info on the 4r100 that says what's what. Anyone have access to fluid-related tolerances as reported by Ford?
I've read about the larger trans pan and heard arguments for and against. Some say that more fluid takes the fluid longer to heat up and therefore results in slightly lower temperatures. Others say that it is only effective to a point and the problem is when the fluid temp finally does get high, it tends to stay high longer. I'm just not sure more fluid is a proper solution.
You suggest installing a different guage. Why should I not have confidence in the Auto Meter? I've read that it's a very good guage when compared to others.

Jones02', I had forgotten that you posted about your highish tranny temps in the other thread!
Ford does have "something" to say. Change it every 30K, more if temps get above 260°.
I would keep your gauge. Autometer is good stuff but would follow housedad's suggestion and add that type of cooler. His last sentence was asking if you thought of installing Differential temp gauges. I don't think it is necessary but I think he may be alluding to the fact that something is causing your tranny to run hotter than most.
I would make sure your have the correct port and that all your connections are tight.

Just as an aside, I have been looking to install this cooler along with my standard V10 cooler.
http://www.dieselsite.com/index.asp?...ROD&ProdID=205
I like what it says about it:
"You CAN run the V-10 upgrade in place of your OEM (see related products below) and then add this Tru-Cool 4739 for even lower temps. We double up like this in our company truck. These two coolers in sequence can still pass the OEM flow rate test with flying colors."
