I've done some experimenting over the years, the setup I like to go with is only using the aftermarket external trans cooler around the end of spring/early summer. I've noticed it allows the motor to run cooler for longer before the fan comes on while in traffic or while the motor is warmed up sitting at idle. I live in New Hampshire, so around fall time, I hook the stock trans cooler back up, from the transmission, the fluid goes into the stock internal cooler first, then into the external, then back to the transmission (mine is the 4.0 with the trans cooler inside the radiator). That way the trans is warmed up and ready to go after warming up on a cold start during the cold months. When I am not using the stock cooler, i leave the transmission fluid inside the stock internal cooler with a hose running from the stock trans cooler inlet to the outlet to prevent anything from getting inside. As stated above, after experimenting over the years during different seasons with below zero temps in the winter, and above 100 temps in the summer, using only the after market external trans cooler in the summer months is what I have found works best for my Jeep.
Great upgrade!! Simple and effective. I think upgrades like this should be done first to your rig instead of adding every kind of light bar on it... performance before ornaments. Can’t wait for the fan installation video to come out
Amen to that! The fan video is going to be a while. I am hvaing trouble dialing in where I want them and what needs to be done to improve efficiency. Once I have it dialed in, I will post a video
Definitely...even if you aren't towing, keeping the automatic transmission cool is essential as heat is what kills them quicker than anything. Far cheaper for roughly $50 transmission cooler than $3k+ for a transmission rebuild or replacement. I think he's also spot on with adding additional electric cooling fans, not necessarily need them running continuously but if you are towing heavy or in heavy traffic being able to turn those auxiliary fans on will not only help cooling the transmission/power steering fluid it'll also push extra air through the condenser helping your air conditioner and through the radiator helping to keep it cool as well...I don't think the clutch fans or hydraulic fans help too much with airflow when you are sitting still.
This is good timing on The Pusher fans that you're trying.I'm actually looking to add a pusher fan on my XJ. I am in the belief that my cooling system works fine,but when I amon the trail crawling and not getting a lot of air through the radiator I'd like to have a backup secondary fan to help cool. I'm also am very big supporter of doing trans coolers even on vehicles that may not necessarily tow. I feel that it extends the life of the transmission. Good mod and nice looking install
hey take a look at the top hose now and see if it is wearing on that hose. but either way i would put something to help protect it from rubbing a hole in it.maybe another piece of hose or wire loom
I thought that they said to have the direction of flow start at the bottom of the cooler and exit the top. Apairently it cools the fluid better and doesn't trap air bubbles.
YES. That is true for the Coolers mounted with the Holes pointed to the SIDE, but the "Stacked Plate" type Coolers should be mounted with Holes UP for maximum efficiency.
Great installation video, haven't taken Cherokee Lee out to the beach yet and it's looking like I'm gonna be giving him to my son (but still doing a few mods like this 1 and running the breathers all to a higher point 1st) I'm gonna stay tuned for the fan video....
Great vid Doug! Great flow, very informative and I love that background jam! 🎶 I'm Glad you found my vid helpful too. Beautifly Elegant! Lol 🤵 Thanks for the solid compliment. 👌 I agree with you... Why would Jeep want to run all that extra line... Either way you mastered it! 👊
My son has a compass and his I hated the thing because the transmission got hot making noise and I believe it was smoking right after he got it,,we went down to the beach...he felt like he failed as a husband and father right then,, it was new, for them, So I assume the transmissions in all these suck?? Could you please tell me what he should do?? Besides adding this little gadget...does he need to do anything further? Thank you so much
just add a bottle or 2 of super coolant and hook a separate toggle switch to your main radiator fans so in case you are sitting in traffic on a hot day or just plain hot, then flip your fans on. It will keep your antifreeze cool and your trans fluid cool through your radiator.
How will this effect your engine temperature now that you have restricted the airflow to the radiator. Jeeps by nature have a small grill area which restricts airflow bye design. Not a good design but it looks cool and jeep ran with it. Will this increase the heatsoak issue? If you don't think a trany cooler restricts airflow hold it up to a fan a see what little air passes through it. What are your thoughts on this? It's funny how the new jeeps come with hood vents. 2020 and they still haven't fixed there heat issue. Sorry I love my jeep just been dealing with heat issues since 1970 on all my jeeps.
I had similar concerns when planning this project. That is why I am planning to add the pusher fans. That said, it is 92 degrees here today and I was just out driving around town for almost an hour with no issue. there seems to be enough air moving through the cooler to keep the radiator cool as well
Video is good to go. Thank you. Going to attempt similar mod on pos nissan altima to try and prevent pos cvt transmission problems. In general, how is your mod working out, and any further advice ref how much additional atv required after the mod? Again thank you for posting this. Good gouge and appreciated.
I have been very happy with it. In fact, I forget it is there because I have no issues with it. This method produced the least leaks (zero leaks) of any I have attempted. Would recommend
Let me know how it goes with the Nissan CVT. I put coolers and magnefine filters and Amsoil ATF in all my automatics. Thinking about doing the same with 2011 Nissan Altima CVT except using the Amsoil CVT fluid.
I think I missed a part. Can you explain a bit? Where is the line flowing fluid from the transmission to the original cooler connected to? There should be 2 lines coming from the Tranny. One coming and one returning. It seems you have used the port entry of the original cooler to connect to the entry port of the new cooler if I am not mistaken. Shouldn't the original port entry be receiving the fluid from the tranny? and the return port of the original cooler should be sending a line to the new transmission cooler being installed (or the top port)? That just leaves the exit port on the new transmission cooler to connect to the line returning to the transmission. I have never done this before but I am trying to understand the schematics of the flow. I only heard you say that one line was returning to the transmission. But which line has been adapted to receive the fluid from the transmission. I think I may have missed that part.
if you install a pusher fan on the new external trans cooler, will it not be pushing air directly into the pusher fan that is located on the engine side and that cools the radiator? Two airstreams will be colliding and that I think will not be good for engine cooling....??/ what do you think??
So then I am thinking, flip the tran cooler fan around so instead of pushing into the cooler, it will pull air through. Not very efficient but heh......
So basically you ran it through the radiator cooler first, then into the external cooler then return back to the transmission? Great fan ideas but I think putting one fan in the middle on the radiator would be better sense the radiator is general is now even restricted more and let the natural flow of air fuse the outside smaller coolers.. just my opinion.
should always use the lower (return) on the rad trans cooler. basicly the way you have it the radiator trans cooler will re heat the trans fluid. the idea of a extra trans cooler is to cool it even more after the rad transcooler.
If you re-route the trans cooler lines for the portion of the radiator straight to the aftermarket cooler you avoid allowing your trans fluid from even coming in contact with a 200 plus degree radiator.
Jeep must of done some changes when designing the WJ vs the ZJ because I have 5 ZJs (a 94 5.2, a 95 4.0 ,2 96 1 4.0, other 5.2, and a 97 5.2) and they all have a tranny cooler but no power steering cooler, that's y I'm thinking on putting power cooler on my 96 5.2 beens that's the one I drive the most, you know if the tranny cooler u installed would work as a power cooler?
Am I missing something, it looks like you unhooked the transmission lines from the radiator, then joined the transmission cooler to the radiator, but how did you hook the transmission lines back up
Wtaht ab winter season like here over north carolina when temperatures are near 25 degrees..? Those transmission coolers will make any damage to the transmission keeping transission fluid very cool cus is very cool climate here...
@@deezneezy412 remember heat and so rises,cool sinks,so better to have the hot fluid coming to the top where most heat will be,which more heat will scape too,and cooler fluid down
I know I'm 7 months late to the party, but to answer your question; the reason to add another cooler is because the manufacturer wants to save money so they factory install a transmission cooler that is good enough for most conditions, most of the time. Heat can cause transmissions to fail prematurely, so it can be a good idea to add something like this to help extend the life of your (very expensive to replace) transmission.
Question: The fill level of my transmission is ok when the engine is off but then it goes down when the engine is idle. Which is correct? I dont want to add to much fluid...
Nice work ! going to do the exact same thing on my WJ. I especially like how you attached the cooler to the brace for Power steering cooler. Great job!
Thanks! I am really happy with this thing. I did some serious towing this summer and the trans stayed cool the whole time, but still warms up quickly in the winter
Did you put it accidentally on the radiator in line? and bypass the radiator? You want it to flow through the radiator then in series go to the cooler. Put it on the radiator OUT line, then to the cooler in then the cooler out to the return line (filter there) Use the radiator to cool the transmission and then the ADDED cooling capacity. Not a big fan of adding hose without saying replace them often. They break down from the inside so it is not a bad idea when adding rubber to also put a filter on the return line...
Others are buying factory cooler with four tubes and install together with aftermarket transmission cooler, and others just disconnect pipes from the current installed factory transmission cooler and take the pipes from the after market transmission cooler and connect it to the return hose pipe and the inlet pipe of the transmission direct. What is your opinion, what do you think is the best? ?
For adding external and keeping OEM tc cooler, which line will i cut to connect to external IN were then exit from external nd go to the oem ? What line is it ! IN or OUT from OEM tc lines? Ty
Aight, this is a little strange for me. My 99 has a factory aux transmission cooler which is mounted on the...tadaaa... right side of the car. How is it that your ps cooler is where the transmission cooler should be? Is it because of your hydro fan?
Yes, it is because of the hydro fan. it needs the PS cooler and I guess they didnt want to cover part of the engine coolant, so they put it in from of the trans cooler side of the rad. I am not sure though
Hey there you seem to be the guy to go to for wj questions. I have a 2004 4.0 and I am going to look at a 2001 4.0 will the transmission directly swap into my 2004?
hey dude great video i like the way bend those tubes. hey just had a question for u i just put in a complete rebuilt transmission in my 2000 honda odyssey. do you think its a good idea to put in a transmission cooler with fan just like what u did.
I imagine it would not hurt. I know those Odysseys are notorious for trans issues, but I am not an expert on them. I would suggest you find a honda forum and ask them there to be sure. I would say it cannot hurt, but someone who works on them routinely can tell you for sure if that trans would benefit from extra cooling.
Why doesn’t anyone remote mount a cooler and fan away from the biggest heat source there is in an engine bay? ........the radiator Why not put it between frame rails under the truck somewhere?
They put it in front of the radiator because THAT'S WHERE THE MOST AIR-FLOW IS . The "biggest heat source in the engine bay" is NOT the Radiator. It is the Exhaust Manifolds. 😁
@@SlikLizrd There’s airflow only as long as it’s moving forward Otherwise it’s useless. But that’s only my opinion, and I’m not an engineer by any stretch of my imagination.
@@Chief6067 The Trans Cooler will reduce the Fluid temps until they reach ambient air temps, whether moving or not. The Efficiency of the cooler will be GREATLY reduced, however. As with anything else, the more air flow over it the cooler it will be. I live in the heart of the desert, and I run a 13,000 btu B & M Stacked Plate cooler on a V-8 engine with a modified Auto Trans -- for long-distance, high-speed touring throughout the deserts and mountains of the American West. Installed about 130,000 miles ago, the B&M Trans cooler has extended the life of the Transmission beyond the normal wear-out time. At 180,000+ miles, Trans still shifts smoothly and crisply, with no discernable slippage. My Trans Cooler is installed 3 inches in front of the AC Condenser -- with NO Fan attached to the cooler.
@@SlikLizrd Thanks for that information about the B&M unit. I was looking at the Derahle unit that has an electric fan on it. I live in a high desert area that usually gets to the triple digits in summer for only about 20 days during the summer but Im thinking on the cautious side and possibly save myself a huge bill for trans repair if I can avoid it.
@@Chief6067 I'm down here in Phoenix, Chief, where it's a plenty hot for 8 months of the year -- never needed a Fan on the Cooler, regardless of load or outside temps. I understand your caution, and your valid concern -- however, a Cooler Fan is another source of potential problems, and should be avoided for that reason. CHEERS !
@@aquaticnstuff7666 If your instructions tell you to run it last it is wrong. the transmission builder wants it before the radiator so if it is very cold the transmission will be warmed by the radiator somewhat to bring it up to operating temp. 135 deg not more than 150 and my 700R4 with a B&M supercooler maintains that perfectly even on the mountain roads.
@@ronaldnelson7204 Interesting theory and I believe it has merit however I am going with the installation instructions especially since my cooler is not that large; and I live in the southeast where it does not get cold very often or the same extremes as the North.
@@aquaticnstuff7666 All I can say about that is you better have a temp gage that reads transmission sump temp and that it stays between 135 and 150 deg. If you want to know more call BowTie overdrives in Hesperia California they know their stuff.
Poor guy has to deal with Ford buckets of bolts design. Their engine compartments look like the engine was installed with a shovel, parts tossed under the hood.

Absolutely. I believe most trucks and SUVs can benefit from this
You definitely need extra air flow on slow trail driving as the regular fan isn't going to cut it at low speeds. The more the airflow the better.
It’s actually good to have the return line go into the cooler.
When your first starting up the vehicle it’ll still help the transmitter warm up.
Yep, saving this video for when I re-route my Xterra's transmission fluid
Good luck with that!
Nice and clean install Doug.

Correct. It’s gotta push up and not fall down.

YES. That is true for the Coolers mounted with the Holes pointed to the SIDE, but the "Stacked Plate" type Coolers should be mounted with Holes UP for maximum efficiency.
good info, I add trans cooler only to delete possible cross contamination coolant/trans.
you need stand off brackets on those hoses for longevity it will rub on the metal at the corners

I live in the heart of the desert, and I run a 13,000 btu B & M Stacked Plate cooler on a V-8 engine with a modified Auto Trans -- for long-distance, high-speed touring throughout the deserts and mountains of the American West.
Installed about 130,000 miles ago, the
B&M Trans cooler has extended the life of the Transmission beyond the normal wear-out time. At 180,000+ miles, Trans still shifts smoothly and crisply, with no discernable slippage.
My Trans Cooler is installed 3 inches in front of the AC Condenser -- with NO Fan attached to the cooler.

Thanks for that information about the B&M unit.
I was looking at the Derahle unit that has an electric fan on it.
I live in a high desert area that usually gets to the triple digits in summer for only about 20 days during the summer but Im thinking on the cautious side and possibly save myself a huge bill for trans repair if I can avoid it.
@@Chief6067 I'm down here in Phoenix, Chief, where it's a plenty hot for 8 months of the year -- never needed a Fan on the Cooler, regardless of load or outside temps.
I understand your caution, and your valid concern -- however, a Cooler Fan is another source of potential problems, and should be avoided for that reason.
CHEERS !

The proper way is to run the after market cooler before the radiator cooler.
Not according to my install instructions
@@aquaticnstuff7666 If your instructions tell you to run it last it is wrong. the transmission builder wants it before the radiator so if it is very cold the transmission will be warmed by the radiator somewhat to bring it up to operating temp. 135 deg not more than 150 and my 700R4 with a B&M supercooler maintains that perfectly even on the mountain roads.
@@ronaldnelson7204 Interesting theory and I believe it has merit however I am going with the installation instructions especially since my cooler is not that large; and I live in the southeast where it does not get cold very often or the same extremes as the North.
@@aquaticnstuff7666 All I can say about that is you better have a temp gage that reads transmission sump temp and that it stays between 135 and 150 deg. If you want to know more call BowTie overdrives in Hesperia California they know their stuff.

Poor guy has to deal with Ford buckets of bolts design. Their engine compartments look like the engine was installed with a shovel, parts tossed under the hood.
