Do i need to get a different filter when i put on a deeper pan to reach lower in the pan to circulate?

 

Yes.

Why the deeper pan? Other than they look nice I don't know of any benefit of a deeper pan.

 

No! The PML pan I put on my X uses the standard OEM filter and pan gasket. You will get new allen head bolts with the pan. Here is the site:

So what you are saying is the 6 quart rear diff cover that I just installed that doubles my rear diff fluid capacity has no benefit?

I disagree! I believe the added fluid capacity extends fluid life since the temperatures will be lower, the larger cover has more surface area to disipate the heat to lower the temperatures and aluminum disipates heat at a higher rate then the OEM steel cover. Seems like some benefits to me.

Would not the same benefits apply to a deeper tranny pan?

Think of it this way; your trans. is going to operate at x (degrees),
by increasing the quantity of fluid,it is still going to operate at x (deg.).

By saying you will lower temps. because of fluid quantity,would twice the extra fluid lower the operating temp even more?
( I know this sounds extreme,but if you had a 8 gallon pan,would the trans.not operate at the same temp?)

There is also something to be said for "mass".(amount of fluid)
it will take longer for your total amount of fluid to get to operating temp.
It will also take longer for it to cool.


Did you notice a change in trans.temp. when you changed your pan?

 

No, they would not.

A diff doesn't have any cooling system other than through the housing and pan. Changing the pan helps here because there isn't anything else.

A trans is different. There is a cooler that has fluid forced through it, and air forced through it. It can dissapate MUCH more heat than you could ever hope to get through a pan.

Another thing to consider is the fluid boundry layer. Fluid near the pan doesn't move. I've observed this, and even measured it, too. The fluid against the pan walls is stagnent. Stagnent fluid doesn't transfer heat very well.

Also, look at the temperature around the trans pan when the truck is running. There is hot air dumped from the radiator that goes under the truck, plus heat from the exhaust. How can you cool something with air that is as hot as what you're trying to cool?

 

Maybe by cooling the oil in the pan it will not let the tranny get to hotter temps easier. The reason Im getting a new pan is that the old one bent by me and this one i found was cheaper and didnt have to worry about bending the lip again.

 

Yes, cooling the oil in the pan will keep the trans from getting hotter.

I just told you why a pan won't cool the oil inside. How do you plan to do it?

 

Just get a nice B&M deep pan , there nice , don't bend , easy to install temp gauge , just drill & tap . I think it helps some with the extra fluid & cooling finns , But a trans cooler is a must & a gauge is good to have , trans temp will kill a trans fast...A good shift kit will help alot to ....

Something else to file in my "I learned something new today" file. Very excellent post Mark.

Do engineers sit around and laugh at some of the stuff A/M companies come up with that actually have NO benefit other than a "look purty"?????

 

I have heard the 08+ pans are larger ( and fit 03-07 ) have a real filter that filters all the fluid and not just 10% like our inline filters. I don't think they are as much $ either.

 

Yes!!!!!

 

I did the swap to the '08 pan myself. The '08 pan is not all that much bigger so maybe it adds 1 qt at most. The benefit is that I now have a real filter element in the tranny and not the simple mesh screen plus I kept the in-line 10% filter. I'd have to find the receipt to check the total cost.
