Talking 2007 Expedition Transmission Temps

Hello All, I am the newbie here but will give this a shot for info. I am looking to see what others are getting for transmission temps if the minitor them. I have an 07 Expy regular WB. I have the HD tow package, but only had the STD cooling package for some reason, 7 row tranny coole. My vehicle was a custom ordered I picked up with a couple thousand miles. I tow a Rockwood travel trailer camper. The camper weighs 7200 lbs loaded and 900 lb on the tongue using a W/D hitch. While on my last trip of 260 miles, normal daily driving the tranmsission runs from 170-195 or 100 degrees above ambient temp. While towing, I run about the same, 190-195, however, while going up a 6 mile hill in the Berkshires in Mass, the transmission hit 210-220. Is that normal, or am I running very hot where I need to look into an aftermarket cooler. Also, do people tow with O/D on or off on flat roads? Thanks!

I think you'll be OK with those temps, as they're rather brief.

If your truck came with the (536)HD tow package...you should have a 7 row cooler...that is 7 finned areas.....the non HD tow package for 07 was 5 finned areas and no brake controller hookup or 7 pin connector.

but I wished that have put on an even bigger cooler....

Sounds like you should be ok though....

I tow a 5000 pound travel trailer with my HD Tow equipped '07 Expedition and have an OBD2 scan gage that monitors several items. I've only seen transmission tempatures higher than 200° one time, two weekends ago, bringing the trailer home via back roads and suburban highways. Maybe 205°. She runs about 165° normally and in the 190° range towing across PA.

Click the image to open in full size.

I can monitor transmission lockup via this gage too and she locks up in all gears so running a lower gear doesn't seem to help. On long grades in the PA mountains she'll downshift to 4th routinely and on very steep occasionally into 3d if I'm running cruise control.

Engine coolant temperatures stay very steady. This is a 50 mile trip on the PA Turnpike and PA997 with the trailer (Sidling Hill rest stop to Gettysburg). This is a graph from a recording OBD2 gage (different gage) from the Interceptor.

Cylinder heat temp is seldom more than 10° higher than coolant temp.

Hey Chuck,

Where did you get that gauge and what do they cost (ballpark figure)? Thanks,

The gage is an Aeroforce.

A couple of things to consider. When set on the top of the dashboard (1) the green is blinding at night, even at the lowest setting. (2) I switched to red which is very nice at night, but hard to see in daylight! Not sure what the happy medium is here.

UTube video.

This device will compute quarter mile times (!), but I've not tried that feature as yet. Be interesting to compare towing vs. non-towing.

It does not. This limits the gage to what you see, it stores no historical data other than some performance data. Would be nice to store things like trans temp. I've alarmed mine for 215°F and the light has never flashed.
