Followup to my last ...

I assume your Silverado has a transmission fluid temp gauge as well as
an engine temp gauge. My Ford F-250 Super Duty does, I know. If I were
noticing higher than normal transmission temps while towing I'd be more
inclined to add an axillary transmission fluid cooler rather than just
increase the capacity of the transmission pan.

If I am not mistaken your truck has the Allison transmission. From what
I've heard, it is a superb transmission for towing ... probably the best
thing GM has going for it in their trucks. Unless it's getting hotter
than normal, I'd leave it alone. Just my humble opinion.

Appreciated. It is the Allison. The book says 200F should be the max,
but I've approached that
several times just on I-95 - during stop and go traffic. But I've also
read that 235 to 260 isn't
unreasonable. I'll look into an auxiliary cooler, if they make one. The
bigger pan increases
capacity by 5 quarts. A friend just installed one.



Your transmission holds about 13 quarts of fluid stock. Adding 5 more
quarts won't make it run any cooler .... it will just take a little
longer to get up to max temp and a little longer to cool down.

There are several auxiliary transmission coolers advertised for your
truck, some fan assisted, some not. You mention that you see the temp
go up in stop and go traffic. Maybe all your factory cooler needs is a
temperature controlled fan that will turn on at a certain setpoint.

I have pretty much the same truck. 140,000 miles, no tranny cooler. But I
only tow about 4500#, but over some steep mountains. Seems to stay normal.
Only time I really saw it climb was a 100+ day! and a 7000' mountain pass.

My trailer runs about 10,500 lbs, but the truck already has a factory installed auxiliary
transmission oil cooler as part of the towing package. I'm beginning to think I'm worrying too much.

If the truck is factory rated to tow that much, leave it alone. The factory ratings are conservative for liability and warranty reasons.

Save your money for another RC airplane!

I agree.... I think the tool is set up to do the job as long as you keep
it tuned...

Here's an interesting and informative piece about Allison transmissions. I'll probably just leave
mine alone for a while. I've never seen the temp get much over 200.

The Pace Arrow Class A motorhome we had for a while had an Allison
transmission. It was the only thing I liked about the whole rig.

Ford sorta copied some of the operating characteristics of the Allison
in the "TorqueShift" transmission used in the Super Duty Series. It
operates similarly to the Allison, including different gear ratios on
the downshifts than the upshifts.

One thing common to both that I assume you do ... always use the
"Tow/Haul" mode when towing. Otherwise, it *may* get hotter than normal.

The FAA, according to an assistant principal at the school we fly at, has written a letter to
Fairfax County Public Schools informing them that the flying activities there are illegal.

Today I joined a flying club http://www.soarcasa.org/ and went out to their Gude Drive site just
north of Rockville, MD. What a super place for flying. I've got to get in some practice. Will try
early tomorrow morning, behind the school about 6:30. Should be safe then.

It has been awhile but I remember always doing another hitch check on
the 5th wheel we had. Manually engage the trailer brakes only and,
while holding them on, try to pull way with the truck. If the hitch
isn't engaged and locked properly, you'll find out in a hurry. This is
done before fully retracting the landing gear.
