I've had one of these in my E99 7.3 for about 5 years now. Not a single leak or issue to date. Really helped keep my trans right at its normal running temp while going down miles of muddy fishing trails during the 100* summer days. It never over heated, but it would raise up to a heavy tow level. By passed the radiator cooler at first and added an auxiliary cooler infront of the radiator at first, which took about 20* off the rise in temps. Added the Derale between that cooler and trans and it never goes over 160.
Bought one of these coolers after seeing your video and a video from Fat Fender Garage and going through a few other reviews. Truck goes into the transmission shop to have the transmission rebuilt tomorrow. Thanks for the great review
Ive got the big mishi 6.0 cooler. I couldnt mount a cooler like yours and use in snow. The mishi isnt cheap. But it is huge and pulls heat.-8 too. I put in the 4.4123 energy bushing kit. Brought my truck up an inch off the dp.
Love all the content in this video, just one thing to be aware of. With a transmission or any closed system with fluid in it that was designed for a certain amount of fluid, adding more capacity does absolutely nothing. All it accomplishes is causing the transmission to take longer to warm up, once that volume of fluid gets up to operating temp it’s all the same. Doesn’t matter if you’ve got 18 quarts or 25+, it’s the same once it gets to operating temp. The cooler is awesome, the aftermarket diff or trans covers are close to worthless especially for the price. There are many videos out there explaining how this works in a technical way that can explain it much better than me.
It also can extend the drain interval, more fluid means more time until it wears out. But I totally agree on it taking more time and having no real benefit for cooling.
I used the 6.0 trans cooler on my 97. Oriley’s had it in stock and it bolted right up between the radiator and a/c condenser. When I had Brian at BTS build my trans he also bent up some new lines for me that work perfect with it and look factory. With the 6.0 trans cooler and BTS transmission I haven’t seen it get over 180 degrees.
Reason why the fan is playing caught up is because fan / cooler is under sized. You should have went with the extreme model. Larger fan and cooler. That's the hyper model
Most transmission fluid starts braking down in the 220-250 range. Your temp gauge is in the transmission pan, which is the coolest temp in your whole transmission. Your torque converter creates a ton of heat, it’s constantly slipping and creating heat unless the torque converter is locked. The torque converter temps can be 40 degrees higher while driving around and all the way up to 100 degrees hotter while towing. So if your transmission fluid temp is 200 degrees while towing or racing your transmission temp in the torque converter could be 240-300 degrees. At this point your transmission fluid is breaking down and causing the wear to the clutches and steals in the trans. There are a few good fluids that done start breaking down until 400 degrees.
What fluid would you recommend for my 95 7.3 E40D? I'm sure it got hot a little while back. It's in the shop due to a flashing overdrive light and hard shifting.
This Chanel is using amsoil signature series trans fluid. That is the best transmission fluid you can buy on the market. This fluid is also the coolest running transmission fluid too. It runs anywhere from 10-40° cooler than normal synthetic transmission fluid.
Good video thanks. I purchase the dame set up also the Derale 14208 trans cooling pan, brother I also wrap the entire downpipe all the way past the transmission that pipe its nearly inches away and well it gets way 🔥. I use a titanium heat wrap. It made a big difference
Energy suspension for your cab bushings. They have a kit with all hardware for under 140 i think. You'll need to make a puller for the original since they are pressed together. A piece of pipe big enough to fit over the bushing a plate with a ⁷/¹⁶ hole in the center and all thread with a washer and nut.
Don’t know how much room the 7.3 power strokes have after you put an intercooler in it. But I have a 7.3 idi and just did a 6.0 powerstroke transmission cooler up front in mine and it works amazing
The hotter atf gets the faster it breaks down. So if you're towing and averaging 210-220F trans temps then you should be changing it at 20-30k miles. If your transmission spends most of its life at ~175 then the fluid should last 100k. However, all automatics wear the clutches and steels over time by design, so you really want to be changing fluid and filter intervals depending on how much use your transmission sees. If you have a stock dodge or ford with a 4 speed auto and you mostly use it for transport with occasional towing, you could probably get away with a 50k service interval. However if you have a 600whp truck with a built trans and you're hot rodding it or really just anything that will cause it to shift under high load conditions, then you should probably cut the service interval back to 20k. These are all approximate numbers and I would just suggest following the manual or asking an experienced builder.
Make a video on your traction bars and where to get them and go more into the trans as far as what you can get for drag racing like a converter locker or trans brake or how ever it works.
So I know on the 6.0 sounds like a similar setup, allow me to clarify what I’m talking about the trans “cooler” in the rad well on the contrary it’s a trans warmer as this video explains a cold transmission is lazy and doesn't operate properly, so to continue to explain ford used the rad to warm the trans to temp in order for it to become functional as soon as possible, then ford also goes and adds a “air to oil” trans cooler for when it gets hot it’s a graceful dance but all you should do is remove the air to oil trans cooler, never the water to trans warmer cause it’ll be a double benefit it’ll use the trans fluid to keep water cooler in turn cooling oil and your good stuff like engine components
I have had a horrible time keeping my 4r100 cool when pulling my 42 foot 5th wheel up the mountain passes. I may try a different torque converter. I also added another remote cooler besides the mishimoto cooler.
It's the cooler bro. I smoked a 4r100 on my 7.3. Truck had 85K on the clock and I was towing my TT up to Tahoe. Thing never stood a chance. Put the Mishi cooler on with the rebuilt I had installed and it's been a night and day difference. Go that route.
I'm currently adding this Derale cooler to my 98 E350 and need the specifics on the fittings you had made up in and out of the transmission. In this video you couldn't remember the thread size/pitch. Do you have that info now that you could provide? Many thanks! Your videos are GREAT!!!
Just wanted to share something..I've been driving a 2018 f550 diesel service body, 18000lbs fully loaded, for about 150k miles here in so cal and AZ. Transmission temp sits at 235 and oil about 225 never had a problem. 2 Ford dealerships said it was fine and I haven't had a problem so I guess they are right?
I’m over 600$ in coolers. Nothings working. 😆 mishimoto. Tru cooler. 6.0 cooler. Deep pan. Towing 14k daily. Fluid currently puking out of front pump seal
Unless u live in the cold north Midwest u don't need pre heated fluid. I even deletes everything on my 7.3 2002 to direct coolers. Just gotta give my truck extra 10 mins to remote start warm up
@@marinusdedreu3833 cause the push start kit comes with a new key fob that has an auto start feature which is great for warming up the ole 7tree in the Winter
Do you ever have an issue with the cooler getting plugged up with junk being thrown at it being in line with the wheel like that? I have one of these coolers and was considering putting it in the same area. I live in the Midwest on a lot of dusty back roads and they get plenty muddy and sloshy during the winter.
Love your set up Brandon!! Is there any way you can find out what the thread size of the fluid in and return of the E40D trans? it would really help me out.
I have a zf5 47 and if I tow it gets hot, I'm curious I'd some one have added a teans cooler and lines, it would probably need a pump to move the fluid 🤷♂️
@@The73Garage I'm really considering buying this, but with the aluminum housing it seems like it doesn't do much cooling without the fan on. I'm going to be towing my 7k pound trailer about 11 hours straight. Think the fan will be able to handle that?

What did the Transmission build cost you?
@@pollackrocket $5,000 and it was absolutely worth every penny. Still the best thing I’ve ever done to the truck.
Been running my trans. Temp at 140
For yrs. No issues.
Reason why the fan is playing caught up is because fan / cooler is under sized. You should have went with the extreme model. Larger fan and cooler. That's the hyper model
If you get rid of all those 90 degree fittings youll get alot more flow though that system.
As far as the cab bushings S&B just came out with the silicone ones! Should be a big upgrade for you
Clean setup man. Love the truck and your clean work.

Lucas Oil atf low viscosity, offers a mercon lv sp replacment. Much smoother. Ill get back to you on the heat this summer

We just installed one on our 1974 C10. Great coolers!
Nice setup and super clean truck man! Some 20x12 welds would look amazing on that thing!
I agree. Trying to look for a set locally!

I have a 2002 SD that I put a Mitsimoro 6 liter cooler on and wow it cools. Mitsimoto makes a 6 liter cooler for the 7.3.
the derale pan has cooler tubes in the bottom and also adds over 8 qaurts of extra fluid.
4.5 quarts to be exact

Invest in a push start kit for the 7.3 you will love it

Where did you get the trans pan?
What if you ran the red oil through that AC condenser? Would it melt the aluminum tubes or joints?
So you al day have it running the fan cooler?

How will this Derale trans cooler and your chosen cooler location do when crossing rivers and creeks??
I work on semis, and power steering fluid goes bad on semis about every 300000 miles. Everything eles should be changed 50k
it's playing catch up because it isn't getting any flow
What would be the best gear ratio to get past 100? I’m trying to build a drag 7.3?
3.73 or 3.55 for top end. I have 3.55’s in my truck.
