can anyone tell me if putting a bigger tanny pan on an f350 superduty wiil help be for i spend 300.00 bucks.....

 

Moved...hope you have a 7.3 in it.

 

The Thicker heavier duty pans add some rigidity to the trans case & the fins on the pan may add some cooling, but the extra capasity (in my oppinion) doesnt really do much other than take longer to get hot.

I personaly dont think they are worth the $$

 

Not sure what your mods are, but IMO you'de be better off installing a bigger tranny cooler than the larger pan if you are concerned about high temps.

 

When I had my transmission rebuilt by a highly recommended rebuilder I asked him to put a MagHytec on which I had purchased. . He was so impressed he became a dealer for them. Btw he also just serviced my tranny after 120,000 on his rebuid. Fluid had never been burnt and he said "C ya in another 100,000." I really believe it was worth the money.

 

It's the extra capacity that makes for more cooling.

IMHO, a wise investment.

 

Some people say that adding fluid capacity takes longer to get hot, and some say it takes longer to get cool if you do get it hot. Instead of working the stock cooler with that much extra capacity, invest in a larger transmission cooler. the 6.0 transmission coolers from te 5r110 torqueshift bolt right up and work great

 

Help with what? What are you trying to improve?

In my opinion all they help with is draining your wallet. If you want to cool the trans, use a better trans cooler. I can't understand how more fluid helps with cooling, and I do have a couple engineering degrees, and I was a trans cooling engineer for three years.

I can see where more fluid will take longer to get hot, but by the same token it will take longer to cool once it does get hot. A bigger cooler is a MUCH better way to cool the trans.

If you just want to help the way the underside of your truck looks, then I agree these pans look better than the stock pan.

 

Of course both are true. It takes more energy to get a larger mass hot and it takes more time to cool off a larger mass.

I agree.

 

Mark, I think the better question to ask you is this. Why would Ford add an external trans cooler if they could get away with a larger pan? After all, the larger pan is way simpler an install than the plumbing to run an extra cooler.

 

Kris, the 6.0 cooler increases 'capacity' substantially!

I agree with both posts #7 and #8 above.

Waste of your time and dollars to replace your pan. Replace your tranny cooler with a larger one.

Oh, and the slower the fluid cools, the better.
Much like engine oil...

 

Much better not to get it hot in the first place.

Neighbors .... I'm no match for your education or experience, but a thought occurs to me that you can evaluate for me. I installed an aluminum transmission pan that increased capacity by 2 quarts on my previous gas powered truck. Transmission temperature went down 20 degrees.

It seems obvious to me that a bigger cooler is a better idea, but if the larger pan is such a poor substitute, why did I get the result that I did?

I think it's this .... the heat source (transmission) varies with load, but if we assume that for any given scenario, the average is going to be roughly constant. So, if the amount of fluid is increased then the heat is applied to a larger volume and the average temp has to go down. Plus, for the time that the oil is sitting in the aluminum pan, the heat is being soaked up by the aluminum. If I remember high school physics ... aluminum takes about twice the energy to increase a degree in temperature than steel.

It's a given that a larger cooler is a much better idea, but I think the aluminum pan has merit (not as much as cooler).

I think that the reason the factory goes for bigger cooler and smaller pan is bang versus buck. The larger pan increases vehicle cost by $20-$30 per vehicle. Bigger cooler might be $5.

Last ... we are hot rodding ( I think) and the dollars spent are to achieve engineering, aesthetic, and impulse goals, not just science.

There it is .... no disrespect intended. I am ready for the pillory.
