Tranny Temp While Towing
I had an AutoMeter Tranny Temp instaled in my 2003 F450 V10 crew cab 4x4, automatic, 4:88 rear.I am towing a 14,500lb 5th wheel. The tranny temp doesn't even read 100degrees f. The technician that installed the gauges says he installed the sensor before the cooler. Can this temp be correct? What temps does the tranny normally run? Can someone shed some light on this for me?
Thanks

No way, something has got to be wrong with the gauge or sender. I have a gauge on my truck and when I'm not towing it reads around 160 to 180 F on a warm summer day. About 120 to 140 during the winter months. Driving hills and only pulling my dirt bike and trailer (700lbs or so) it can go up to about 220 F. My sender is also placed before the coolers, both stock and aux units. Even if the sender was placed on the cooled line, I would think you would see some reading with the load your pulling.

I agree something is wrong. On a cool day 50 degrees mine may get to 130 to 140. During the extreme heat of summer mine will go to 170 max, not towing. Towing a 7,000 lb travel trailer last summer 92 degrees the highest it ever got was 185. My sender is located in the transmission case, so my out line temps may actually be higher. I also have a Hayden 679 aux cooler installed with a Imperial electric fan. I only turn the fan on at very slow speeds, or while backing. I think you may have a problem with yours indicating correctly. I would definitely have it checked.

Tranny Temp While Towing
I just returned from a 2000 mile round trip to Iowa from OK. I have an 89 E350, 460, E4OD, 4.10 & 30.4" tires. I also pull a 5th wheel in the +12k range. GVCW is approx 20K.
My trans temp runs about 124 & the rear end runs about 140 to 180 depending on road speed. Trans goes up to about 180 manuvering in campgrounds. I have an external filter, and the sender is in the hot line @ the filter.
Hope this helps
