First off - price- Who has the best prices- Genos is higher than Xtreme. I know there is probably someone else that can beat 251.75 for the 11.5 rearend.

Secondly on the 48re transmission pan-I have conflicting input from a couple people. One guy says it will help another says its a waste of money. What is the consensus? Will the deeper pan help? TC is being updated to a tripple lock with one piece input and a solid flexplate.

 

If you are trying to cool the trans going down the road, get more trans cooler. The only thing a larger pan will do is give you more oil to heat up (longer warm up); it may drop oil temp by 2 or 3F, but you'll get better results with more cooler.

There's a reason the major trans companies install a deeper trans pan. Cooler running tranny. For example, before I put my double deep on I could easily hit 220* sitting at a stop light in the summer. Now I'm suprised if I hit 190*. As soon as I start moving the trans temps drop to 140* or below (my gauge only reads to 140*). Even when doing slow speed crawling in the mud, I can't get it over 180*. I definately recommend putting the double deep on. I've got my probe in the line coming straight off of the torque converter so I can get the fluid before it hits the cooler.

 

not much help here, but I'm getting just the normal MAg tech on my tranny soon. 260ish IIRC.

 

Might have a lightly used one for sale, getting rid of the truck. I will let you know.

 

Dan Marino,

You'll find that Mag Hytec has a pretty good lock on their dealers and prices, doubt you'll find it anywhere much less! We don't sell thier product but the pans we do sell will drop trans fluid temps 25-30 degrees. If you have a MAJOR trans fluid temp problem, you need to go to a larger cooler, if you need a 25-30 degree drop this usually does it. The double deep pan is not worth the money to me, as the pans we sell hold an extra 2 quarts and get the same degree of fluid temp drop, so why add fluid on top of more fluid if you still get the same temp drop??

Personally I think the "only" reason to install these "heavy duty" aluminum pans is for structural integrity. They really strengthen the tranny case when you add them. If you have a good cooling system you really don't need one. They might add fluid, but they do not aid in cooling. The added fluid "helps" only because it takes longer to "heat" the extra fluid, but it takes longer to cool more fluid too.

 

Remember, I live in Texas. More is better and to much is just right.

 

The bigger pans have more surface area to disipate heat and it spreads the heat over a larger volume of fluid. Takes longer to heat 13 quarts than 8 quarts. Less stress on the fluid as it is constantly circulated. The tranny fluid sees the tranny 50% less of the time. My tranny runs so cool now that I have it modded it doesn't matter to me but my fluid is holding up great and if you touch the fins on the bottom of the pan after towing heavy it will burn ya yet the tranny gauge still reads cool... for $200 bucks that I paid on a $9k tranny rebuilt and fix it is worth it to me plus it looks cool bolted on that bright orange tranny. ks

 

It doesn't matter, if you measure at the outlet of the tranny, "X" amount of fluid is going through the tranny at a time, the bigger pan does nothing about it. So "X" amount of fluid at 200* or 240* is still the same. The pan is nothing more than a resevoir. Try backing up a hill with a 10+K trailer, it will get hot. And you said it, it takes twice as long to get hot and twice as long to cool. The amount of cooling from the pan is minimal.

 

Mcmopar,

Done the test myself towing the race car trailer to Texas. Recorded ambient air temps and such towed to Texas, raced and had fun while there we changed the pan and topped up the fluid. We got anywhere form 10-35 degrees cooler fluids temps from the pan alone! Plus we picked up some weight while atthe Track with soem engines we purchased, and the ambient air temps were within 5 degres on the trip home (they were hotter).
Works the same way as a oil cooler, more surface area and better thermal conductivity! Aluminum has the capacity to transfer heat better, then you add the cooling fins and the larger pan size and it gets yuo cooler fluid. Now I agree with you some brands add waaaaaaay tooooooo much fluid and it just sits there and really only delays average fluid temps, but the PML pans don't do that. They ran some tests and found that by adding 2 quarts (in the Dodge applications, more in others) you got the same cooling effect as adding 6-10, so why add it??? If you need a 20-30 degree temp drop a good pan will do it, if you need more you need a bigger cooler, but 20-30 is all most folks need.

That is good to know, I find it interesting that the "fins" if you want to call them that on a pan such as the Mag-hytech help at all. They are very small. I do have to say that that MH pan is a NICE product, the workmanship seems top notch.

 

One thing no one has mentioned yet is that the log style engine heat exchanger on the block of the Cummins plays a huge role in trans temps.When the engine is fully warmed up this cooler is actually a heater until the trans output temps get above coolant temps.So going down the road in lockup,i have seen this happen.Trans output temp 140-after log cooler,160, after cooler in front back to 145.When I removed the log cooler and did my twins,my trans cruise temps dropped 75 degrees in the winter and 40 in the summer,just because the log cooler wasnt heating my fluid anymore.This was just by removing the log cooler,no other cooler was added!Later I added a 40000 GVWR cooler,which dropped temps even more.At slow speeds,stop and go driving,the log cooler is doing the majority of the work,pulling most of the temp off the ATF,then the up front cooler finishes,it isnt as efficent now because your not moving alot of air across it.If you are towing heavy and the coolant temps rise to 210,the trans temps will follow up about 20 degrees also,because it has too.A double deep does help with trans temps,it will not do much to lower your lowest temp your now seeing,usually 140ish cruising,but it will clip the extreme temps you see by a solid 15-20 degrees.I have plowed with and without the DD mag hytec,and it dropped temps a solid 20 degrees in tight parking lots. They also should be on every trans that is behind an engine with 450RWHP on 2wd's,and 400Hp on 4x4s,due to the added ridgidity and structural support.If youve every had a 47/48 case stripped,when tanking them,you'd see that it isnt particularly beefy,and has a thin area thru the 2nd apply area,the Mag hytec pan holds it all together.

 

group buy going on on the other dodge ram site (diesel ram forums) the price is 239.00 for the "deep" pan and 209.00 for the "standard" pan

 

i run the pml tranny pan- i i can tell you that it does not drop your fluid temps 25-30 degrees. i have seen no drop in temps!!!
