I am going to install a Mag-Hytec transmission pan on my SD.On the instructions they tell you to use their LE 1150 Mercon or (“LE” 7500 Monolec Power Fluid for sever service and HD applications). Is this necessary or just stick with a reputable brand of mercon v? Any other install tips would be appreciated. Thanks.

 

I have run my aluminum Mag-Hytec for 4 years now and I ran the type fluid that Ford suggests. I hooked a trans temp line to the pan too. Ford came out with a better fluid since the truck was made, I think it's Mercon V? Anyway, I have had no problems and have a great time towing with my 1999 Super Duty 4x4 crew cab LB.

 

Use any fluid you as long it is at least Mercon (V for 5r110 transmissions) rated. I put Royal Purple in mine and it's doing fine. They are just pushing an add on sale and they probably use someone elses Mercon V fluid in their packaging.

 

Um...I'm pretty sure the 5R110(TorqShift) trannies use Mercon SP...Mercon V will damage these trannies!

 

Yep. Only SP goes in the 5R110 (torqshift).

 

I have the 4r110 so I don't keep up so well with the new fluids ford keeps coming out with. Listen to the other advice if you have the 5r trans.

 

Guys, thanks for your replies.I figured the dude from mag-hytec was jus pushin his stuff.My truck is an 01 V10 SD CC 4x4.Unless im mistaken the tranny is a 4R100.Mercon V is recommended.Upon further reading, especially from the master,Kovalsky say im just throwin my $$$ away on this deeper pan.Is this true?

 

I don't think so. The amount of heat being produced by the trans should be a constant (or mostly so) so your spreading that heat across more media. Not to mention, your pushing the bottom of the pan closer to the air flow, aluminum transfers heat better than steel, You now have a drain plug ( I don't think the stock had drains or magnetic plugs.)

 

There's no such thing as a 4R110. There was a 4R100 and then a 5R110.

Most of you have read about my opinions on deep pans. For those who haven't, read on.

A deep pan is excellent for making the bottom of your truck look cool. That's all it does for you. It does NOT make the trans cooler, but it will make it take longer to get hot. Once it does get hot it will take longer to cool. I can't understand how that helps.

There is very little heat loss through the pan. You need fluid to move around the pan surface to transfer heat. I've measured the flow inside the pan, there is a pretty steady surface that "sticks" to the pan, and that blocks heat transfer.

Another thing to consider is where the pan is located. Ever get under a truck that's been running hard while the engine is still running? How about standing next to a running, hot truck? Do you feel nice cool air coming from underneath? I feel HOT air. I've measured the air temperature around the trans pan. It's often in the 230-250F range. How well will the pan cool the trans fluid when the air around it is hotter than the ATF? I seem to remember from my heat transfer classes that you can't cool something with something else that is hotter. That means that the expensive aluminum pan is not going to transfer much heat, but what little is does transfer will be from outside into the ATF!!!!

A big pan looks nice. If that's what you want it for, then go for it. If you expect it to cool the trans, or make the trans last longer, a better trans cooler would be MUCH more effective.

 

My opinion on them is, whether you have 5 liters of fluid or 50 liters, the heat output on the transmission is fairly constant. While the transcooler can only dump so many watts of heat over a given time, the wattage is spread across a greater volume means lesser heat is going into the cooler and the cooler is actually running the fluid to a lower temperature than the reduced capacity system. So cooler fluid is being returned from the cooler and circulated into the pan. Unless the transmission is producing more heat because of a transpan change, I can expect a minimal drop in fluid temperature.

 

I'll put my money on Mark....
