Aux Transmission Cooler

[Skandocious]

Well I did a google search too but none of them looked EXACTLY like mine (with the little squiggly pieces of metal between the plates). I've just always been told to upgrade the "stock" cooler to a stacked plate cooler. Why would people tell me that if I've already got one...?

 

[TheRoadVirus]

I think that the pictures just aren't close enough that you can see the pieces of metal between the plates..

Easier to see here

Ah, I can't find much of anything while searching. Maybe they were wrong, lol. I'm sure there's always way to upgrade, though. How big (roughly) is the cooler you've got now? I'm not sure but maybe you can use a smaller electric fan as a pusher for when you're not moving to cool her faster?

Regardless of it being stock... Is it a 'stacked-plate' type cooler? I've been told to upgrade to a stacked plate cooler but if I'm already there, why bother?

Upgrade the factory set-up with a "stacked plate" cooler wether you already have a stacked plate cooler or not. In your case, this would mean get rid of your current stacked plate cooler, bypass the oil cooler in the radiator and get a single stacked plate cooler with enough capacity to exceed the capacity of the current factory set up. I have always found the stacked plate coolers to be rated by GVW....so however much your truck weighs plus whatever you will tow should tell you the minimal amount of capacity you need.

Fair enough. I was looking at the Ford Racing stacked plate cooler, which is just about the exact same dimensions as mine... I figured why waste the money on a cooler thats essentially the same as the one I have now...

Here's the one I was looking at...

Says it's rated for 18,000 GVW. Why can't my stock one (same dimensions) be rated for that same weight?

My assumption would be that the FMS one has finer fins which would dissipate more heat than the thicker more spread out fins.

My cooler is 1.5X11X7. My van had just the radiator for cooling. I bypassed that and just use the auxilary cooler.

Get the thickest cooler you can get without going wide and long so that you get lots of capacty without covering up much of the radiator.

Look at B&M's line up on the summit site.

Well I don't want to get one that's too think because I plan on getting a pusher fan for it. My current electric fan pulls most of its air through the bottom 2/3 of the radiator and the tranny cooler is mounted at the top corner (not great for pulling air through the cooler). Here's the fan I was looking at:

The only problem with a pusher fan is they will block any extra airflow you would get from higher speeds.

Damnit... So what the hell am I supposed to do?! I can't imagine my efan is moving much air through the cooler if at all right now...

 

[surewhynot]

The pusher may work fine. Just at highway speeds, where air would normal out push a puller fan, you will still only get the amount of airflow that the pusher fan puts out.

Did that make any sense?

 

[lil_dq]

It is a reversable fan, is there enough room for it to be a puller fan then maybe you could get the ari flow through it at higher speeds?


ok reading tonys post....

If you put it in as a pusher fan wouldn't it block the cooler, so at higher speeds less air. and as a puller it will suck air through and at higher speeds just be spun faster as the air goes through the cooler?

No explanation needed. As soon as you said it in the prior post it made perfect sense, not sure why I didn't think of it before.

Well the fan above moves 800cfm... So if you're right about the high speed air being limited by the fan's cfm, then 800 should be ample for that little cooler no matter WHAT speed I'm moving at. No?

Well, whatever works. I don't use a fan for it so that was a non issue for me. But, if you can spare another 0.75 inches and I can't imagine space is tight enough to where you can't, go for a cooler w/ similar dimensions that is 1.5 inches thick as opposed to 0.75 inches thick. That extra 0.75 iches makes a big difference.

Or use a big and thick cooler with no fan at all.

 

[surewhynot]

I would think so, but thats not based on experience at all. Somebody else may know better.

Already though about it... I suppose I could rig up something fancy by pushing the cooler out close to the grill and slipping a puller behind it... The mounting would probably be kind tough though, especially since I don't have the tools or expertise for fabricating my own brackets.

Heck go to any welding shop or such and see if they have any scrap steel laying around you can get it for cheap( if they are small enough prob free!), cut and bend it or cut the peices you need and have the welding shop weld it for ya.

Here ya go:

With this cooler you ought to be able to mount it up to where your Taurus fan covers a good portion the cooler. With the heat dissipation capacity of the 9X11X1.5 cooler + some of which covered by the fan you already have I can't imagine you would have any problems. Installation should be easier and you won't have the extra current draw of the fan.

If I were to go 1.5" thick, I think I'd be more apt to go with this one:

Little smaller, but cheaper and comes with an install kit. I think 7.25x11x1.5 + pusher fan should be ample, no? B&M says its rated at 14,400 BTU... Whatever that means

 

[Mr. Stroker]

Whats the need for a bigger trans cooler? Honestly i cant see the trans being any cooler than what you got it at now, especially with your pan.

 

[eco]

It's technical semantics, but the core of that cooler is really 6X11X1.5 - you are looking at the overall dimensions.

Anyways, it's all a compromise I would say. Would you rather have a smaller cooler and a fan or a bigger cooler and no fan? Is the cost, inconvenience (wiring, space consumption etc.) and downside (less air at highway speeds, current draw etc.) of the fan worth it? If the cooler is in a space where the other fan does it no good, the pusher would help at low speeds, stop and go traffick ect., but the cooler could easily be relocated to where the other fan covers it and presumably, the other fan would need to be on too during those stop and go conditions. Do you want both fans draining your alt?

I went through this same dilema a while back and opted for one big cooler without a dedicated fan that is partially covered by the radiator fan.
