Trans pan, Mag-hytec vs Derale vs other??

[44magnum]

Title says it all, thinking of getting a better trans pan when I do my next oil change, so which one to get? Mag-hytec is $365 Derale is $160, I'm assuming there are others but I figure these are the main two, so does anyone have any experience with either? How much does the Mag-hytec drop tans temps? The derale is said to drop 20-50 but I cant seem to find what the temp change should be on a Mag-hytec. I see the Mag is aluminum and the Derale is steel. Both have magnetic drain plugs, but I have an aux filter I'm adding at the same time so that doesn't really matter. The only problem I could possibly see with the Derale is the cooling "tubes" getting plugged, but I dont work in mud or snow or even dirt roads, so I dont think that would be a big problem. First I have to see what pan I have, I know I have the internal filter but apparently there are 2 different pans? Do they mean one with external filter and one with internal filter, or two different one with internal filter? Thanks in advance for any/all input.

Subscribed. I have this same thought. I hope we get some good answers.

OK guys here goes. I had a change to get a free rear axle cover or a transmission
cover from Mag-Hytec So one day I was up at Lead Hill, Arkansas and I dropped in to see Brian at BTS.

He said don't get the transmission cover, it does hold more oil and it takes it longer to heat up when it's real
cold outside and in the summer time, it's just that much more oil to keep cool.
So I went and got the Mag-Hytec rear axle cover. Love it.

"and in the summer time, it's just that much more oil to keep cool."

This guy must smoke crack.

you won't believe how many people stick with that school of thought
Look at John Wood's they only put stock pans on His.

I think the larger surface area of a larger pan will decrease heat or even the steel pan with the tubes assuming air circulates threw them would be a benefit

but No MFG's seem to put real world data out there

Also make sure if you have the newer in pan filter that these will work .

there are two 5r100 pan styles now,,I see MagHytec has 2 but not Derale ? but the Derale has the 5r100 and a "W" listed
so maybe they figured a way to have 1 pan fit both? that would be cool I might get that and a in pan filter ,, thx for the idea

Brian at BTS is one of the best 4r100 tranny builders in the country if not the best. he knows what he is talking about. That being said I run a mag hytec tranny pan as well as a rear diff cover. The tranny pan will keep your tranny cooler longer, but once the fluid gets really hot it will take a little longer to cool back down.

agreed
but if it's just a temporary temperature spike like a hill climb etc
the extra fluid could be the difference between a big problem or just an slight increase in temps IMHO

That right there is why I run one. On long pulls it takes the fluid longer to heat up than a stock pan.

I can see how it could be an issue in the winter, Although I cant imagine it would take that much longer to warm up. But nomatter I live in Texas and don't have to worry about that. As for the having to cool more oil in the summer, I don't understand that. And why dosnt that theory hold true for the diff cover? Isnt it bigger than stock as well? Did he say the oil cooler was too small to efficiently handle the added oil? I would think if that theory held true Mag-Hytec and the others would make a stock size pan with the cooling fins/tunnels, then they would get even greater temp drops. (Or smaller than stock+fins= the greatest temp drop of all?) Anyway I wasn't really asking if it cooled, I have seen plenty of independent test that confirm that this type of pan does lower oil temp. Hell if it raised my temps I would take it off and kill someone with it. If I'm wrong and someone can prove it to me, feel free. I'm not trying to piss anyone off, and I'm not calling anyone a lier, I just don't understand it. Thanks again Guys
