I have a 06 F150, with the 5.4, and 4R75E trans with the stock trans cooler.

While pulling my 30ft trailer trans temp is 205-238Fpeak. 150-170 is normal range.

I was looking at the Troyer cooler to add inline after the stock cooler.

But then got wondering if it would work if i just bought one of their 10" fans, with the 180-170 thermostat, and installed it on the stock cooler??

Has anybody tried this?? Can't see why it won't work...but thought i'd ask before i order.
Thanks.

 

The stock cooler on your model is pretty large (if you have the towing package). A dedicated fan for it would definitely help and then you wouldn't have to **** around changing the trans lines either.

 

Or what about installing two 8" fans on stock cooler...but that would cost $212 plus shipping....which when the cooler and fan are only $280 plus shipping.... so probably worth going that way if your only going to save $68 ?? I'm not sure if the stock cooler and even 2 fans would be enough? Although i'm not sure how much airflow the stock cooler gets where it is....fans may do the job?

 

Yes i do have the tow package...so it is a fairly large cooler. And yes that was my same thoughts...more connections meens possible leaks....and more hassle.

 

I am having the same problem towing my 27' camper, just ordered the troyer cooler hopefully i will be putting it in next weekend.

 

If you could let us know how it works out for ya. As I have been looking at it for a while now. I'm in the same boat as you guys. I am hoping with this and the troyer vavle body and larger oil pan the trans will keep temps down.

 

I'm just installing the Troyer kit now.....I'll be hooking on my trailer on Wed....so i'll let u know how it works.

 

Please let me know how it does! LOL Tranny is next on the list and going to add the Troyer trans cooler and valve body along with a larger trans pan! Keep me updated please.

 

It is possible to add two or three 4" Computer Fans to your cooler. When used in a "Pusher" configuration they can work very well. Pusher meaning mounted to the front of the cooler; away from the radiator side. Radio Shack does sell a suitable fan for cooling computer cabinets. These are not the little clip on fans used for u-Processors that have little heat sinks attached. They are what we used to call "Muffin Fans" that are around 5-6" box square.


There are two such fans mounted on my transmission cooler that I added by default. Here is the rub; mine are connected to a controller unit IFB.
I designed and built it out of spare electronic parts and therefore its not available in a store.
If you do decide to add such fans you can safely attach both fans to the cooler, and than supply power and ground to them from an accessory or accessories circuit ran from off the engine. Since both fans are 12V, and have negligible current (>1Amp. ea.) it shouldn't be too hard. However be careful with your polarity when making such connections (+12V) is the red lead for such fans available from Radio Shack or similar. Make sure that your wiring is "Mil-Spec", and weather tight and use wire capable of being exposed to weather. I don't have pictures since I didn't think it would have been of interest.

 

I got my troyer tranny cooler all in, I ended up leaving my stock one in and and adding the troyer as a secondary cooler. I will be taking my camper to florida next week I will let you know how it does.

 

I may be missing something, but the computer fans themselves would not be weather/water resistant?

I'm looking to add an SD cooler to mine, and was considering adding a fan, too, while I'm at it. Wondering if there's a junkyard solution? Motorcycle radiator fan, maybe?

I have found with my SD cooler that a fan is not necessary. It mounts in the middle of the rad at the top rad support so it gets great airflow both from driving and from the truck fan pulling air through the rad. When I get enough time I have to put on the Troyer Efans and I am hoping that they pull even more air through it.

 

Thanks, Griz. I was concerned about low-speed effectiveness, but didn't consider the engine fan pulling air through.

Well i just drove over 700 miles pulling my trailer with a bike in the back...about 7000 lbs. Troyer cooler worked great. Max TFT i saw saw was 200 on a long hill. Ran in the 175 range most of the time. But was down in the 150-160's some times.

I left in my stock cooler and plumbed it into the return line as they suggest. Well worth the money IMO.

 

Thanks man! Going to get this and there valve body with a larger trans pan in the next month or two.
