Improving the 7.3 transmission cooler

rammertide07 · #1 Wed, February 23rd, 2011, 02:04 PM

I found a parts list to install a 6.0 cooler on a 7.3- Includes:
8 x 1/2" Heavy Duty Clamps
6' x 1/2" Trans/Oil Cooler Line
2 x 3/8"-1/2" Adapters

On the trans/oil cooler line...is that just automotive hose? Is there anything missing?...other than the 6.0 cooler? I also saw some transmission coolers at an auto parts store a while back that had coolers for small cars up to big box trucks (some had fans on them). Wasnt sure if those would work just as good or would it be best to stick with the 6.0 cooler???

And the BIG question (drum roll): Where exactly is the transmission cooler

I thought it was on the front but someone told me it is the power steering cooler. If ya'll have any links to share that is more complete than what I found, please do share.

Thanks!!!

Like this:

BD Diesel Performance US Transmission Cooler Install Kit c/w Toggle Switch - Ford/Chev 5/16" Tube

Maybe pair 2 of these up

Well I am no diesel guy, but last I checked the power steering didnt get hot enough to need a separate cooler... you steering that much?

So I agree with you, the radiator in front of your radiator is most likely the tranny cooler, I have one and that is also where it is located

There are numerous vehicles (cars and trucks) that use power steering coolers, including our Superdutys.

Dont forget......power steering pumps run the HydroBoost (brakes) also.

OP, the trans cooler is behind the intercooler, in front of the radiator.

Can I splice another cooler in the line somewhere and mount it on the frame???

Also, just thinking, during the summer I need something to help keep y transmission cooler. But during the winter I want it be a little warmer (or at least warm up faster). Why dont they make a cooler that has vanes that can close/open...hooked up to a thermostat getting temp readings off the transmission???? Just pondering

Just do a search for a trans cooler with a thermal bypass...

Otherwise Jegs or Summit sells a cooler thermostat that can be plumbed into the system.

Thanks man. So I can splice another cooler into the line somewhere?

I dont know that I would run 3 tranny coolers, but relocating a single cooler should not be an issue.
