You have a 5 speed automatic, 2500 lbs. is what I would consider a light trailer. What is your gear ratio? That plays a big part in the mountains. What you need to know is when/if your transmission is in overdrive and "hunting" up and down in gears, you should down shift. The first thing you should buy is a VeePeak WiFi OBD2 adapter (@$20 on Amazon) and then purchase Torque Pro($5) app if you have an Android phone or Dash Command(@$6) app if you use an iPhone. Then you can see actual temps instead of the idiot needle on your dash. It will also allow you to read, fix, & reset check engine light codes, use heads up display gauges at night, etc. Excessive heat DEFINITELY eats transmissions! If it didn't, then BTS wouldn't require the use of the 6.0 cooler to be eligible for warranty replacement. If they are high, you could install the 26 row trans cooler that came in 6.0 diesel vans. It is also an easy bolt in. Either way, you are generally better off with one big cooler than adding a second to the existing. This is because of more restriction in the flow. Cheers!

My 2010 E350 has the 4spd tranny with a 3.73 limited slip.
I haven't delt with the newer ford trannys. My 95 Bronco has the old 4OED ford transmission and it runs hot which is common and the heat is known to eat the transmission.
Is the newer 4R75E prone to run hot? If it is, I'll upgrade the cooler, if people don't have heat issues then Ill leave the factory 11 row cooler.

Paging JWA! JWA, where are you?

Hasn't he posted extensively about thermostats on the Ford Truck forum?

And now we wait...

OK, so you have a 4R100. Like I said, I would look at actual temps on an OBD2 app or Scanguage first, and then address any issues. With 3.73 gearing and stock size tires, you should be fine. Increase your tire size much, and effective gear ratio drops towards 3.55. Not good in the mountains. For engine temps, I would make sure the cooling system is flushed, new coolant, cap and all up to par and then address any additional needs. Your engine is going to register extra hot while idling parked so keep that in mind too. Cheers!

I do not recommend a lower temp T-stat in Triton motor. They are supposed to run a little warm for efficiency. I've been loaded to nearly 24,000 pounds and pulled the westbound grade out of death valley (12-14%) on a 107 degree day, and my coolant temp never went over 222F, even though I have the Banks PowerPack and a tuner. I only had to pull over because by rear diff was overheating.

Now Im confused...
According to the info sheet on my 2010 E350 5.4L. Its supposed to have a 4R75W tranny. According to the dealer it has a 4R70E tranny, and now on here I see someone is calling it a 4R100. Dam Fords!!!! GM is so much easier!

My question is still not fully answered. Do the newer Ford trannys run hot and warrant an aftermarket cooler that is bigger than the factory cooler?


Also, I was wrong thinking that the Triton 5.4L was in the E series.

Look at the mfr data plate on the driver's door jamb for trans code...and post that here and/or google it.

I have a 2008 5.4L, trans code Q, which is a 4R75E

"Runs hot" is a relative term........the stock trans coolers are fine unless you are doing heavy towing or steep mountain passes in the summer......and of course cooler is better for the trans fluid....up to a point

You have a 5.4L Triton V10 with the 4R75E transmission with a 20-row cooler (same as the V10) and it holds 13.2 quarts of fluid and is rated for "lifetime" service.

The transmissions do not run hot, and IMO you do not need a larger cooler unless you are exceeding the original specifications somehow, which would include larger tires than 245s, exceeding the GCWR (12k or 13k depending on rear axle ratio), or crawling in low-range. Or if you add anything up front which would reduce airflow. In my case my Buckstop and offroad lights did block air and made temps higher, so I added the 40k cooler as a result.

Got a ScanGauge II today.
Now I have to figure out how to add water temp and tranny temp to it.

Now I just need to add the trans temp feature and the motor temp....
I'm fat and slow, unfortunately those are my good qualities.
