Question: the cooler recommended Hayden 699, on the official website Hayden and on Amazon says it doesn't fit 2017 model. I have a 2017 and I bought the model 699. Can I plan to install it or it will not fit?

[@MrRangerZr1]

@@radoo2341 It'll fit any car, universal. Never rely on amazon's fitment guide.

I have this exact cooler on my 2004 Volvo XC70, and this video helped me determine how to mount this to the AC condenser on mine. Did a full 16-quart Amsoil Synthetic ATF flush, bypassed the main radiator, and she's shifting very happily, now. Thanks a bunch!

Awesome man

[@louisfredgagnon]

Awesome ! I got my ac condenser and my auto trans rad sitting on the table. Your video helped me (it will) although my 5at acura tsx tranny might be different from yours ( routing the tubes ). I'll attempt the install tomorrow alongside the ac condenser, dryer, pag46 and 134a refill, wish me GL :$

[@stockholm2375]

Wish I had thought of loosening the condenser brackets, I just put the plastic rods through both the radiator and condenser and reached through the fans to trim them/lock them into place. Was a pain but it worked out.

[@yasha1928]

Thank you for this video! I installed my cooler yesterday by trying to "guess" which hose was feed & return and well, I surely had it backwards! Now it's the right way & it appears the previous owners never maintained the fluid as my van is constantly getting better & better. Have a good day!

[@buddyrebel_Garcia]

Just do a bypass! Just install it to the external trans cooler and nothing gonna happen unless you live in the cold winter states but in California I will definitely do this since it’s 24 seven hot all the time

[@rosieclark3661]

You will be surprised at how many people don’t until start having shifting issues or a complete fail due overheating primarily you should change your ATF every 30,000 miles at least just think of if as extended engine oil change but it must be done

[@DRVe]

Great video on installation. But I have a very important question that no one mention in their video's. All is great on the installation but how much more ATF oil needs to be added after the cooler installation? Because 3.3L for my 2003 odyssey shows empty.

[@MrRangerZr1]

Depends on your cooler size but yes check fluid level after install

[@ryang5441]

Thanks for the tutorial! I have an 04 pilot and I’m trying to delete the stock cooler (so it can’t fail and put coolant in my transmission), do you think the Hayden 699 in the description would be good enough for that? Would it be too overpowered and result in a transmission that doesn’t warm up properly?

[@MrRangerZr1]

That's the best one to get! It has a thermal bypass so the ATF will get to operating temp just fine.

[@tp9825]

Hi Mr Ranzer you are the boss of the Hondas. I learn a lot from yuor videos which saves me money. I have a 2008 odyssey exl and recently my transmission slips only in second gear. My buddy already changed 2 shift solenoid B AND C but still it didnt fix the problem. Fluid has been changed recently like 15k miles ago. what do you think it could be? please suggest as i cant afford new car right now.TIA

[@MrRangerZr1]

These 5-speed transmission never gave me issues. As a last try, change the ATF again. This time in place of a quart of ATF, use lucas transmission additive. It's a thick red fluid. If that doesn't work, replace the transmission with a used low mileage transmission. Don't bother with rebuilding.

[@coreyang08]

Am I wrong to assume that you capped off the actual and original cooling hard lines once you installed the aftermarket trans cooler? I'm sure no one leaves it opened to the element or maybe it doesn't matter? Thanks for sharing and uploading!

[@MrRangerZr1]

Nothing is left uncapped, you just add the cooler in line with the factory system as shown in the video.

[@lopez8871]

so on a 14 odyssey could i use the 11/32 hose the kit came with?? or what size hose should i buy? by the way you got some great informative videos.

[@MrRangerZr1]

Use 3/8". Link in description.

I have code P0751 on my Honda Odyssey only during the transmission problem otherwise it will not show up when scanned. First it happened in the highway, it was a terrible jerking. Second time wasn’t that bad, car will not move forward or backwards. Third time kicking and moved very slowly. I install a transmission cooler system, because it just happens when hot. After 2 weeks it did it again after stoping it would not move. I noticed it’s doing it when driving like a madman and when hot otherwise it will not act like that but likely jerk from 1 to 2. The P0751 code is the shift solenoid valve A, I am not sure if replacing it will fix the problem because everything is fine until It gets hot. All the mechanics Recomend to put a rebuild transmission. My transmisión was rebuild at 121000 and now is 153000. Any suggestions?

[@MrRangerZr1]

What year odyssey?

[@richardcurtis8026]

I'm adding a cooler to my 04 Pilot so I can plow snow. So how do I know what line is the return? You just pointed, but didn't really explain it. They look the same in the video so would I be looking for the lower one?

[@MrRangerZr1]

When the car is warmed up, whichever line is coolest to the touch is the return line.

[@elcolin_]

Did you notice any difference in performance afterwards? Did you measure temperatures before vs after in any way? Would love to know

[@MrRangerZr1]

Depends how you drive, environment, but my temps stay around the same not overheating temps.

[@hj9808]

Thanks for the detailed tutorial. Just curious thou, It seems like you did not remove original tranny cooler in this video. Should I remove the stock cooler or leave it there?

[@MrRangerZr1]

The new cooler is used with the factory cooler, it's in line with the factory cooler.

[@petec9686]

Great video. To the point, no fluff or annoying music!!!! My 2010 Odyssey's lines to stock cooler are leaking badly, so time to do the cooler upgrade. Looks as though you leave the stock cooler in the loop. Is this before or after the external cooler? I would guess that having it after might be best as it would act as a coolant heater in conditions where the external cooler is doing too good a job. Since I am replacing all hoses, how much will I need? Is it the same hose (3/8) all around? Do you recommend the combo package on amazon that includes hayden cooler, hose and thermostat bypass?

[@MrRangerZr1]

Check the description for the cooler I highly recommend. I just installed the one I showed for demonstration purposes but that is also working just fine.

[@aHmongUS92]

Is this what saves the transmission? I hear about this part that will save you all sorts of trouble from the transmission failing if driven & maintained well.

[@MrRangerZr1]

Yes can make the transmission last longer

[@yt-itzluckygamer8537]

I got a question I got a 05 Honda Civic automatic and got a universal transmission cooler and my lines run from my trans to radiator so when I install trans cooler do I just connect the lines from trans to trans cooler instead of trans lines to radiator?

[@MrRangerZr1]

No keep the stock cooler in line, just add the new cooler to the system.

[@martinradtke5181]

Sir, as you've already know I prefer to over maintain (follow the "Severe Duty" Maintenance Schedule) provided by manufacturers. Is there a way to mount oil cooler using frame instead of plastics ties to Condenser & Radiator?

[@MrRangerZr1]

Yes. Nothing wrong in using the plastic ties, they work fine.

[@atx-cvpi_99]

Yeah you want the transmission cooler as close as possible to the condenser.

[@KanonLooksLikeL]

nice vid but how to test the cooler? how do i know if the cooler is clogged or working properly?

[@MrRangerZr1]

One line should be cooler than the other

[@CH-do7sw]

According to the short video I saw, the transmission oil first enters the water tank and then passes through the oil cooler for secondary heat dissipation, right?

[@MrRangerZr1]

basically this new cooler is an additional cooler

[@ricardoramos1242]

Is there a way to check the transmission fluid temperature with an simple OBD2 scanner (with an app, for example) or another way without a scanner that reads transmission codes?

[@MrRangerZr1]

Scangauge with the certain software can read the ATF temp. Best scanner I use on a daily basis is the bluedriver.

I live in an area that gets very cold in the winter, will a transmission cooler make it harder for the transmission to get to operating temperature?

no. get a cooler with a built in bypass, it'll heat up the atf quicker then start cooling. check the first link in the description.

[@ChrisSglimbeaelectricfingers]

Doesn't hurt at all to add

[@richarddavis4895]

Ok so you route the top hose to the radiator? But where at on the radiator? And the bottom hose to the transmission??? But where at on the transmission?? There’s two lines running from the transmission to the radiator is it the top one or bottom one?

[@MrRangerZr1]

Watch the video I show the routing

[@Ruffstuffbud12]

In this setup does the fluid go through the cooler then to the radiator? Or does it come from the radiator through the new cooler then back to the transmission

[@Ruffstuffbud12]

Wondering because I did mine the same way but added a magnafine filter right off the bottom of the cooler with the flow going to the driver side. Want to make sure it's not the wrong way and potentially going to clog

[@MrRangerZr1]

Just make sure the arrow on the filter is on the return line going back to the transmission.

So then hot transmission fluid will interfere with the efficiency of your air conditioner.

[@MrRangerZr1]

How?

[@keepingup2952]

@@MrRangerZr1 It's not only partially blocking the condenser from airflow, but also the air flowing through it is heated, heating the condenser which lowers the efficiency of the air conditioning.

[@edwinalexander1170]

@@keepingup2952 i think it is impossible because as the car is moving the air will constantly striking off the tube and the fins like high speed wind cooling it down, and the condenser will get the same air flow as the fins have spaces to each other, and still there are 2 moving fans when temperature raises to cool down condenser and radiator nothing will affect the condenser performance as it will continualy get the flow of air.

[@keepingup2952]

@@edwinalexander1170 But the air coming off of the cooler is much hotter than the air would have been naturally, without the cooler being there. Also, the velocity (volume/time) of that hot air is diminished due to the presence of the cooler compared to the scenario without the cooler. Any device, even a finned tube structure, will slow the air velocity.

[@edwinalexander1170]

@@keepingup2952 The effect on the condenser is minimum, as this cooler is just a quarter the size of Condenser, still the wide area of the condenser will be getting sufficient air flow, even the part of which the cooler is installed both the fins of the condenser and the cooler will get sufficient air. And as the car is moving the air flowing through both condenser and the cooler is so intense, heat will be dispersed in the air as usual. have you noted the way winds flow to you when riding a motorcycle at high speed. It is so intense the same will keep going through the condenser and the cooler. The condenser will still keep working well.
