Max Temp while towing

[rpatton]

What does everyone think is the magic number while towing that you would start to be concerned. Right now I see a few deg. either side of 190 deg at roughly 75 ambiant temp ouside with the oil about 5-6 deg higher.

It's more important to be keeping an eye on your exhaust temperature

The 5R110 will be fine up around 200-225*F. Any higher and you will put your transmission at risk for decreased life and is indicative of an internal problem. These transmissions are well designed for towing and can run a bit hotter than the 4R100 in the 7.3's.

I tow a heavy toyhauler with my truck on 35" tires. I spent a warm weekend in the desert this past weekend. My tranny temps never made it to the 180* mark on my gauge. I had a headwind most of the way home. I even took my truck out to play in the dirt some and playing around in the sand I never reached the 180* mark. I would freek out if my temps got up to 200*.

You should tow heavy when it is 115* outside. I have seen 215 while pulling a grade in summertime.

Thanks guys I guess that I need to keep right around 200 or below. I personaly have not seen 200 myself pulling 10,000 lbs
