actually running thru the radiator is for colder climates,for warming the trans fluid up, id run without the engines radiator hooked up , just hook up trans up to external fluid cooler,and you can even mount a small electric fan to cooler with remote switch, plus you never have to worry about an internal rupture in radiator mixing antifreeze in ur trans
I plan to tow random things up to 9,500 lbs, cold and hot weather, highways and desert.
Will the single small trans cooler be enough? Our should i run one big one or two small ones?
Any recommendation for type of small fan to use?
I haven't added a Trans temp gauge yet, but i know it was running hot last time i was towing.
The end-tank radiator cooler is not only for cold climates. It will take a large chunk of the heat of the fluid. Without the radiator cooler, your transmission temperature will rocket up during periods of high-load, low/no ground speed since there will not be much air flowing. You should have it setup so the fluid enters the radiator cooler first, then goes through front mount air-oil cooler
Also, are you sure its a cooler the previous owner added? The 460 Trucks came with a front mount cooler that was of a similar size stock. If they completely bypassed the radiator cooler, and are only using the small stock front-mount, your transmission will get hot, real easily.
If you're going to be towing ~10,000 pounds regularly, put the the radiator cooler back in circuit, and put the biggest transmission cooler you can find up front.
Thanks for the info. You can tell the previous owner added the cooler because it has aftermarket mounts, zip ties and mounted funny.
When i replace replace radiator, i will run the Trans fluid thru the radiator, then thru the Trans cooler. I will also install a larger one.
Instead of a new large cooler, can i use one of another ford?
