How hot is your tranny getting? On a longer 6-7% grade mine will run 150-175° and my coolers bypassed.

Truckers, lets see your rigs!

Sounds like I just need to send this one to you to sprinkle some magic on it. Either that or you can just take the gauge out of it....I'm betting you don't run a gauge on transmission temperature.

Dad’s truck had the water cooler when it was a 10spd, swapped in the 13spd and put an air cooler on it. Cooler started leaking so I looped the hoses and it made zero difference in temp between all 3 setups. So when I swapped my engines I ordered the $10 block off plate and threw the “cooler” on the scrap pile.
Since the harness I used was for a Pete glider I never got around to moving the gauge wires. They’re virtual gauges on the nav screen. However there are 2-3 other setups identical to mine and they don’t have temp issues so until it starts puking oil out of the seals......
Friend had 9 coal trucks in eastern KY for years and said 90% had the lines looped. So if they can load 50 ton in a bucket and roll through the mountains, mine should live an easy life.

Eh what's the problem? The genius that hooked it up put both coolant tubes to the high pressure side. It was doing nothing!
Put an air cooler on my headache rack and haven't seen anywhere near 200 since. Thats with the new spec Eaton oil which is thinner than previous. But I also cruise in direct now which makes a huge difference.

And your making the same power as a stock C16 and hauling 1/2 a load. Completely shocked yours isn’t getting hot.

Well it was in Montana at elevation and 105+ degrees with a sidewind. Usually when you get into the elevation it cools right off but I doubt you easterners know that.

At 105* your trans is considered “normal” at 100-120* over ambient air temp which would be 205-225. Eaton considers 250-300 hot and even then they consider it acceptable for short term use.
Trans temp is like intake air and water temp. Everyone picks a random number out of thin air and considers it the “max”

It was around 260 IIRC and I could hear chattering. But those conditions were the worst I have ever seen.

They say conventional oil starts breaking down at what 230-250°? Something like that anyways, so I usually use that as my reference. If the oils still able to lubricate it's not too hot. Oh and I run west too and even at 80k pounds and it 90+ degrees outside I've never had mine go above 175 on a longer pull and I have no cooler. I never did understand how using hot water was supposed to cool it.

Liquid exchanger is to help get to target temp. If the trans is cold, get to operating temp, if it's hot, shed heat to the cooling system.

I figured you'd tell me something like that...problem is my driver has a gauge and won't let me take it out now, so I'll have to get more cooler in it. I have asked him 5 times what happens if he backs down a gear and rolls on with no response.

Ya God forbid you miss a gear and have to drop two! I've seen guys slow down to 20ish miles an hour at the bottom of the grape vine in Cali just so they don't have to down shift going up....
I wonder how much of a difference in temp would input shaft speed make when under sustained heavy load? Could you're high temps possibly be related to the driver lugging it down too much before dropping a gear? I wouldn't think it'd matter since either way the gearbox is under load but that's starting to get into things that are above my pay grade.

From the coal haulers, he said if the cooler isn’t mounted in the grill of the truck don’t waste your time. There isn’t enough air flow under the truck on a hard slow pull to make any difference. We used to mount them under the truck on these gliders and have since just used the bypass plates with the same results.

The heavy haul truck I still work on added a liquid to air with an electric fan between the posts of the rack and claim not to have been past 200 since.
They threw a fit when the truck was new because it got hot pulling the hill at e-town on I65.

I've heard of guys doing some special coating (not microblue FFS) on all the gears and such. One guy has never seen above 130f without a cooler. He runs thinner oil too.

I can believe that. I've seen a couple transmissions lost due to air coolers being underneath. To me that's barely better than a water to oil cooler on top of the tranny. The kind with the shifter. No the other kind. You're a sick ****.
Ive heard heavy haulers - the REAL heavy kind - put them on the headache rack with a big fan or like you said in the grill. Nothing else works.

Copy that. I think we're talking 45mph or so, but I'll see how much room I have in the grill. That new big fan pulling air through it would be the best thing.
Thanks for all the advice guys. I'm sure we're not causing any major damage to the transmission, just my brain.

I used to pull a quad axle dump bucket with 39 ton plus in it thru the Adirondacks with the regular old barrel cooler. I didnt have the power allen has but I never saw much more then 10-15 degrees difference from coolant.
