Take one 5.0 or 5.3 put a heavy load on it, and have the fan kick in, especially if its a seven blade fan, and you will notice a drop in power. In this case the owner has a 6.0 so it shouldn't be a noticeable factor. Asking questions is how one makes a diagnosis. Try it sometime. Whitelightning

Let me see now, when it is hot outside and I am chillin with ac and towing a heavy load up a long hill on hiway (like I did a few weeks ago when it was 95 out) am I worried about losing 5hp (give or take) for cooling fan? Not at all, my first concern is it stay cool. I have yet to get my 2000 K3500 to brake a sweet no matter what I do. I can stop is traffic on a 90 plus day with A/C on towing a heavy load and the tempature never climbs. (it is impressive) It has a factory HD system with a 10 bladed clutch fan that does its job when needed.

And I used to run 10 to 15% kerosene in my automatic trannies when it got to 50 below, so what? I used to drag in the 80's with a friend, alchol and the hole bit running over 700hp on a built up THM 400 with a 5500 RPM stall converter. We ran regualr ATF and never lost first tranny but did a few engines and rear axles until the quirks were works out. Sure maybe it works for you but you have no data to support that it would have not done the same with just ATF in it and a 10 or 12 sec blast down a strip is nothing like hauling 10 or 12k up a hill on interstate when it is 90 plus outside.

Al;

Before I put this in customers' vehicles, we ran it in:

86 Ford Ranger
84 Dodge B-350
86 Bonneville
91 Dynasty
92 Voyager

it works, and works well; currently have at least 30 HD vehicles out with
this mix

the only one I'd be leery of is the Mopars that use the ATF-4, it might
cause TCC chatter

you ever actually try plumbing it this way? it works fine on my '88 K2500 w/ a 700-r4. it shifts fine when it's -15F (3 out of 4 mornings in January), my AC works wonderfully even when it's 98F out (aka last week). my truck's temp doesn't creep up anymore while pulling my 14ft box trailer loaded at 6500lbs, like it did plumbed conventionally. I also dropped my trans temp from 225F to 175F while towing my trailer. your logic boggles the mind as far as heat transfer goes... I don't even know where to start. the heat shed by the external trans cooler is but a fart in the wind compared to a 250F-300F AC condensor. -Bret

You have never seen -50, I have and minus 30 or 40 a lot. Strange thins happen at those temps. ALso because you do not understand the physics of heat exchange it does not make them change to your liking. Your logic is the bizzare one because the 250 to 300 degree temps you claim exist only in the first few passes in condesor. You need to cooling it to close to ambient to get best cooling from A/C and better than half the condensor is used to lower the refrigerant that last 30 or 40 degrees The laws of thermodynamics tell you that as the tempature differentail between the item being cooled on the ambient air decreases the efficency of the heat transfer drops as well and if you use a aux cooler incorrectly it impeds this process by placing more warm air than needs to be in front of condensor and reduces the cooling of the freon. Calling this process a "fart in the wind" just tends to show a lack of understanding of the whole process and the thought that goes into designing one from the factory. Also GM gave up trying to get their A/C to cool properly all the time and Dmax powered trucks because before 2004 and 1/2 model. The intercooler was in front of condensor (simular to a big aux tranny cooler) they has since relocated it behind the AC condensor and resigned themselves to using a bigger intercooler in a warmer airstream.

Guess you are smarter than Detriot huh? I do not know who is more foolish here or who to feel sorry for, a guy that claims to be a expert tranny guy promotting it or the poor sole that takes the advise.

How does using that mix affect shift quality? I'm assuming it makes
it firmer?

Yea right and detriot is stupid too. Guys like you change this from design specs and then blame OEM when things go bad. ATF has a much different detergent base too than engine oil and different seal conditioners too but you might know that if you were really knowledable on the subject and not just read a artical in a forum thread and declared yourself a expert.

I thought there would be a change in shifts, but no, it felt the same

Yes and the simple minded are so easy to amuse too. Geenrally those that try to belittle others are very insecure in themselves so they attack others to feel good. What ever "floats your boat"

Its more than 5 hp, it can be as much as 20 hp, which is why we use electric
fans
on the dragster. You also don't have the smaller v-8 in that 3500, so it
darn sure
better not "break a sweat". And you have the heavy duty cooling system that
goes with it.
But again with out asking, your just making assumptions, something your very
good at,
that his rig is the same as your rig. Those of us who earn/earned our
living turning wrenches
learn real fast never assume.
