Question about the tranny cooler on 6 liter trucks

[Lonesome7.3]

I have not been around many six liter powered SuperDuties so I do not know about what they have. I was at a shop today that was swapping in a new six liter. On the ground was the radiator and a huge tranny cooler. This thing was like two feet by two feet. I am wondering if this cooler is only on certain models. Is there a special reason for such a huge cooler? I have cooled my E4ODs with much smaller coolers and put them through a lot of abuse. I am wondering what the benefit if to suck a huge cooler.

All the F-series with a 6.0 come with a 30 row trans cooler. 7.3's came with a 12 row. Bigger is always better on trans coolers.

thanks for the info, i never knew that... would an aftermarket one be worth buying or is the stock one strong enough

I've had 18k behind my truck and never gotten over 175° with the stock cooler. I'm gonna put a deeper aluminum pan on to get the extra capacity and a little cooler temp. Never had an issue with stock though.

i didn't think so.. only time I've heard of upgrades was when someone had a pull truck

Not sure if you will actually see cooler temps going deeper in the pan.

Since these trannies have a "T-stat" in them. Towing, I bet you will still see those temps.

But, will be interested in what you do end up seeing.

I have a Mag Hightech pan and some comercial style coolers on my OBS. AFter that I can pull our horse trailer even with my 22.5 adapters and the tranny stays nice and cool. However, I am considering using one of those huge coolers from a six liter. After doing some more reading it would appear they work with the T-stat though. So it is my understanding that I would not be better off using one. Am I correct?

The thermostat isn't in the cooler itself. You would greatly benefit from the upgrade.

Then what what is the point in the T-stat?

Not sure. All i know is that 90% of the fluid never makes it to the cooler until the temp reaches 165°.
