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.





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.



http://dmaxstore.com/index.php?main_page=product_info&cPath=16_363&prod ucts_id=668&zenid=2euu9fpbqf4tmumt6ecj7kbu74








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.

I'm having a little trouble with "different gear ratios" going down
verses going up. There's only one collection of planetary gear sets
in an automatic. The ratios don't change.



I think I screwed that up. It's not different gear ratios, but rather
different shift pressures (when using the tow/haul mode). For example,
like the Allison, the Ford Torqshift will sense when going downhill and
automatically downshift to apply engine braking on gas engines, saving
wear on the brakes. Doesn't apply to diesels, since a diesel has no
engine braking.


If I set the cruise control to 45 mph (for example) and am in tow/haul
mode, the transmission will
downshift using the engine to keep the speed there. If the cruise
control is not set, but I'm in
tow/haul mode, the transmission will sense my slowing down, with or
without the brake, and downshift
- if, for example, I'm approaching a red light.



The Ford Torqshift does the same in Tow/Haul. Only difference is that
with your rig being a diesel you don't get any engine braking when
going down hills like you will with a gas engine.

Modern diesel engines do have engine brakes.

"Jake" brakes have been around for a long time. The "Valve" type is
likely what GM is using on the Duramax. They are exhaust brakes as I
understand them. It's still not compression based engine braking as in
gas engines.

I think the article said the system uses *vacuum* by means of opening

It's too bad you totally missed the subject of this conversation
although it doesn't surprise me.

John was not asking about transmission coolers.

He was asking about an aftermarket transmission pan that holds
additional fluid. The concept being that more fluid equates to lower
transmission temperatures.

Tests have not proven this to be true. All the bigger pan with more
fluid does is increase the time to get up to temp slightly and increase
the time to cool back down.

Everyone here, including me, recommended an auxiliary transmission
cooler, especially for towing. Turns out John's truck *has* one that
was factory installed.

Go practice your bass.

SNERK......that Dickson is always a dollar short and a day late.

About 10 years ago when I was planning to drive my 95 Plymouth Voyager mini van up to Quebec to buy my Sandpiper 565 sailboat, I had a transmission cooler installed because of the dubious reputation of Chrysler transmissions at that time.
Brother in law offered me use of his Dodge Ram pickup so I took advantage of that.
Seems to me that the RAV4 came with some kind of cooler and I had no problem towing 33 percent above it's rated capacity....well maybe climbing long hills where my speed would drop 20 mph below posted speed.

I would look into a cooler for the Highlander if I upgraded to a heavier boat upwards of 3000 towing weight even though it's rated for 5000 lbs.
Better safe than sorry.

**** YOU ASSCRACK. I guess it really bothers you that someone OTHER than your wrinkled ass, knows something.

YOU....also stated earlier in the thread that " after it warms up " your transmission works better. Well, its a Ford for one thing, and two : Trannys run better when COOL. Fords suck anyway, just like you.

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.

I'm having a little trouble with "different gear ratios" going down
verses going up. There's only one collection of planetary gear sets
in an automatic. The ratios don't change.



I think I screwed that up. It's not different gear ratios, but rather
different shift pressures (when using the tow/haul mode). For example,
like the Allison, the Ford Torqshift will sense when going downhill and
automatically downshift to apply engine braking on gas engines, saving
wear on the brakes. Doesn't apply to diesels, since a diesel has no
engine braking.


If I set the cruise control to 45 mph (for example) and am in tow/haul
mode, the transmission will
downshift using the engine to keep the speed there. If the cruise
control is not set, but I'm in
tow/haul mode, the transmission will sense my slowing down, with or
without the brake, and downshift
- if, for example, I'm approaching a red light.



The Ford Torqshift does the same in Tow/Haul. Only difference is that
with your rig being a diesel you don't get any engine braking when
going down hills like you will with a gas engine.

Modern diesel engines do have engine brakes.

It sure feels like I'm getting engine braking when approaching a stop sign in tow/haul mode. If the
T/H button is not pressed, there is no braking - just like a regular automatic transmission.
