Default Lower tranny temps can help power???

True or False:

By lowering your tranny fluid temps you can gain back power to the ground that is lost through an automatic.

I'm not sure of the answer but I'm just curious of what it would be. Since heat robs horse power it only seems natural to think that cooler tranny fluid temps can help.

Anyone have any ideas?

That would really only have and affect if the trans was getting hot to the point of slipping , reguarless of temp the trans just transfers power. Though cooler temps may increase its life span.
so in a nut shell FALSE

In order to understand the answer, you must first understand the question,,, or at least the thoughts behind it right?

The reason heat is not condusive to making horsepower is the fact that when air is hot it is very thin... not many oxygen molecules per cubic foot of air. Conversely, when air is cool or cold it is more dense... therefore more oxygen molecules and that makes for a much more efficient combustion of the fuel... more / better combustion = more Horsepower!

So, understanding that set of facts, it can easily be said that indeed transmission temp has no bearing on power levels.

Hope that helps.

I understand about cooler air making more power within the engine. I was just referring to the converter and transmission building up heat and whether or not it would make any difference in power at the wheels. I figured friction builds heat... Lower the heat, reduce the friction... It's just a question I asked myself today and wondered if it made any difference. Thanks for the input guys. Now I know!
