Is putting a tranny cooler worth it?

[soloscaperman]

I have notice that I am getting more and more Mulch and gravel jobs. I will be snow plowing again this year. I think my truck has a stock tranny cooler which is located near the grill. I heard that it doesn't do that much.

So how many of you guys put coolers on your transmission's that do full time work from plowing to top soil, carrying fire wood, etc.

My truck is an older 87 F-350 that I use for plowing.

It came with a piggy-backed after market cooler as it is a 1 ton cab and chassis. The main cooler is incorporated in the radiator. I'm pretty sure that is the same on GM vehicles, and it sounds like you already have an extra cooler.

When plowing your not getting the air flow from driving so yes, an aftermarket cooler is definitively the way to go. Make sure you use a quality cooler as you can minimize fluid flow if the tubing is too restrictive.

A good temp gauge for your tranny will be the best way to monitor tranny temps.

as the guy above me said, anytime your doing trailer pulling, or hevy load hauling, an OVERSIZED external cooler is the way to go, but be sure to check that you don't already have such installed

Keep your plow angled as much as possoble. When it is more fresh air reach the truck. If it is straight it blocks air flow.

I believe so long you change your transmission fluid and filter every 10,000 miles, you shouldn't have any problems.
Then you need to check that POS and make sure it really IS a tranny cooler.
Because that's what I thought mine was, come to find out it's an OIL cooler...
As in, engine oil.

And maybe that's what you guys are talking about but it made a world of difference to me.
Because I now disconnect each hose when changing the oil to make sure I get all of that stuff in there, too.

Then, the hoses...
Are made of a rubber that can (and does) deteriorate, at least mine are.
When (yes, when) it springs a leak it helps to have some kind of a way to get home or to fix it up.

A tranny cooler is not just a good idea, but it is imperative for any hard pulling or workout such as plowing. Moving snow will KILL a tranny. It's the constant forward-reverse shifting that does it, It is imperative that this fluid be kept cooler. Now, before we get solded for mentioning anything about snowplowing on here (and redirected to plowsite), let me reiterate that his is super beneficial to just pulling, also.

My 6.0 PSD ford came with this tiny little cooler. My aftermarket temp gauge would read about 175 pulling trailers. I changed it out for the largest cooler I could fit. Temps dropped to 145 with same trailer. Decided that I was going to add an aftermarket B&M transmission pan with aluminum cooling fins. It holds an extra 8 quarts of the good stuff. My temps have now dropped to 105 with the same trailer, 95 degrees, and the AC roaring. The fluid will live forever at that temp, but I still change it at 35000 miles. Lot cheaper than a transmission on the diesels. My vote is for the pan and cooler. Hope this helps:waving:
