Getting Hot

[Vortex]

I just got a 2006 F350 with a 8/10 in lift, 37 in Procomp Extremes, 4 in Silverline exhaust, Airraid Intake and Edge Attitude. I have a 30' toy hauler (tow trailer) loaded about 11,000 lbs going up the 15 freeway about an 8-10% uphill grade. My temp was up at 230 getting near red and had to slow down to 30 MPH. I had an F250 V-10 before that went up the same hill at 30 MPH and would come close to over heating as will. I bought the diesel thinking I would be able to pull the hill at like 50 - 55 MPH no problem. Any reason why I'm overheating or do the diesels run hot and I should just bury the peddle and not worry about it?

for clarity sake
are you still running 3.55 gears ?

 

[Vortex]

It has 3.73 gears

 

[powerboatr]

3.73's thanks
plus 37 inch tires,
boost psi?
EGT ?
RPM?
gear?
pulling 11k up 8% grade
ground speed?
i would geuss you were lugging the heck out of it
and she got HOT

we have a severe grade and its only 1.8 miles long 600 foot climb, 3rd or 4th 1250 egts 30 psi boost, pulling the wagon

nope i wouldnt bury the peddle and keep going, or you wont be long on the tranny and engine.

Here is a little info for ya

Automatic transmission fluid will provide 100,000 miles of service before oxidation occurs under normal operating temperatures of about 170°F. Above normal operating temperatures, the oxidation rate doubles (useful life of fluid is cut in half) with each 20° increase in temperature.
The approximate life expectancy at various temperatures is as follows:

175°F 100,000 miles
195°F 50,000 miles
212°F 25,000 miles
235°F 12,000 miles
255°F 6,250 miles
275°F 3,000 miles
295°F 1,500 miles
315°F 750 miles
335°F 325 miles
355°F 160 miles
375°F 80 miles
390°F 40 miles
415°F Less than 30 minutes

This information clearly shows why transmission oil coolers and the various maintenance intervals are recommended for severe usage.

Above 300°F, the metals inside the transmission will warp and distort in varying degrees depending on the severity of overheat. Because this damage occurs and fluid life is so seriously impaired, rocking out of snow, mud or sand should never exceed a very few minutes.

Big K, That is some useful info Thanks

is that picture off the back of a B&M cooler? im sure ive seen that before....

and votex get some 4.10 at least with those 37 inch monsters.....

also if your trans fluids getting hot theres something else you can try... get a deeper trans pan.

for clarity's sake is this the trans temp or the engine temp that you have put a real guage on or has ford actually started putting numbers on the dash instead of just "normal"

i have to asssssume he has a real water temp gauge, the factory one is C--------H no numbers

to many unkowns,
