I installed a bypass trans cooler on my Escalade because I live in Arizona and would operate 20 degrees higher than normal operating temperature. Now that it’s bypassed, it runs at the correct temperature even in the 110 degree summers.
No need to bypass in the winter. Minnesota here, 210k+ on my trans and I got a big 11 x 11 hayden cooler, bypassed the rad for the last 7 years, never a problem.
Thank you. Straight documented results. No flawed theory or BS discussion - just before/after comparison. Well done. That said, many modern systems run with a small 'thermostat' that must be bypassed, like in my Crown Vic. Thermostat bypasses the cooler until it reaches 180 degrees or so. There are kits to eliminate the thermostat, which I have done AND added an additional cooler. Other systems utilize engine coolant in a heat exchange unit such as in my Jaguar XK. In that case I replaced the factory cooler with a heavy duty unit and eliminated the transmission coolant loop from the engine cooling system. Now they're completely independent and have fewer failure points overall - like a normal, old fashioned car.
The drop in temperature with the cooler installed was mainly caused by colder air hitting it at 60mph. The fan on that cooler isn’t going to be of much help. The large hub of the fan covers most of the surface area of that cooler; barely any blade coverage. A fan with a much smaller hub would be better. Ever stand directly under a ceiling fan and notice that when you step to the side a little, you get more air blown on you? Plus the two bars also impede what flow that fan will provide.
I don't care how big your cooler is...your transmission will never run too cold. Oh, if it's 30 below zero, when you first start the vehicle...sure it will run too cold for a few minutes....but, not for long
or just place a cover over the cooler, the Radiator cooler works both ways to strip heat and transfer heat so it can also warm the transmission oil in the winter, but will have to watch the temps and see where they go
Beautiful seeing those temps drop. I have the same radiator, engine/trans, in my 06 TJ and my transmission temps are a lot more than I'd like them to be and it's not even hot out. Might have to give this cooler a try.
@@user-gb1ne5jj8v nah, it needed a cooler 100%. I am at a much better temperature now with my Hayden 689 installed. I was hitting 220 degrees on a cool spring day before just driving on the freeway, this is a fresh build mind you with only a few hundred miles on the new oil.
@@user-gb1ne5jj8v I think you are jumping to conclusions. 220 is certainly on the hotter side but that's not really indicative of a bad transmission or bad oil. That means the transmission just isn't being cooled properly.
was just thinking about installing a cooler on my future daughter-in-law's '15 civic because it has a CVT, & u do know they r not good wen u hav 80k... i also use & sell AMSOIL, so between the 2 i believe it will add long life 2 that trans... can't believe the drop in temp... liked the vid, good job my friend...
If your TC has a thermostat in the condenser u should in line new cooler after ur condenser , that way no matter what ambient temps are , the TC will always keep the warmed up oil temps to operate correctly which in return the new cooler will keep ut from not going too high ,,,
I have a 2007 dodge 2500 Cummins 48r factory large transmission cooler it has a bypass built in. It's like a cheap 40K cooler. They go for like $120 or $10 at a pick a part. Keeps the 6l80 under 165f towing in 110f ambient. Never seen higher than 170f doing some hard wheeling under 10mph.
All alI know about the inlet and outlet lines, is that the inlet to the radiator is from the bottom, in order to kick out all the air from inside, and the outlet is at the top of the radiator.
Hey. Bro I put a thurmstat on my cooler. So when it is cold it runs throw the stock rad to wome it up then when it gets to 160 it opened and lets the fluid go to the cooler. Works like a champ
I saw those too. The only problem with that is 180 degrees is much warmer than the transmission needs to run. It's clearly not excessively hot, but with heat accelerating the degradation of everything from clutch packs to rubber seals, I'd prefer to run the transmission only as warm as necessary. Someone should make a lower temp thermostat that opens at around 120-140 degrees, that's still plenty warm. For people who don't want to use a thermostat for whatever reason, covering or partially covering the cooler during the winter can be an option too.
Whoa my cvt on my Altima would run 240 and after the cooler it’s at 230 I changed the trans fluid and filters and still nothing tried 2 different ways to run transmission lines
You can buy a fan kit that puts a thermostat in line and will only work if it gets over a certain temp. I have one that turns on at 180 and off at 165. I bought the kit from AMERICAN VOLT on eBay and its worked well so far. They also sell different rating thermostats to turn on at lower temps or up to 210.
I hate those clamps, I wish they used better hosing and proper clamps. It came with he braised line ? Or you bought those separately? Do you need to add additional ATF using the cooler ?
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? ?
It's a hayden 676. Personally I'd opt for the 697,698,699 internally bypassed coolers instead if you live in a cold climate. They're only $50 @ rockauto
i have a 2014 jeep grand i drive on the beach you think i should install it to on the beach its hotter and i you air down to 12 and drive in 1 low 4x4 ,,,,,ty i like ur video by the way
yep great job, but only really good if towing or racing or heavy duty work for the transmission ,still a good external trans cooler will help extend the oil life and the transmission as well. :)
Was your transmission overheating? I have an 08 patriot and just on normal driving on the interstate for about 35 minutes and I get a trans temp light and the car gods into limp mode.
I have a trans coole twice that size on my 14 tacoma...it cools about 20 degrees here in az hear ....i wont believe that little cooler will drop temps 60 degrees....lets go brandon🤡🤡🤡

You can choose a Hayden cooler with patented automatic internal by-pass for colder climates (winter)
@@Capdan365 would it be the 699 model?? Im in the midwest and get both brutal heat and cold so this would be perfect
@@Capdan365 697,698,699 are all internal bypass designed.
Thank you for reporting back. How is it running now ?
@@billythomas4527 240 something and still running well.
Mate you need the hot entering from the bottom and cold out the top of factory transmission cooler to stop air bubbles.

That's why I put a huge 25 row stacked plate DeRale in a little Jetta.
60° is huge drop in the temp.
Might have to bypass it in the winter.
But time will tell.

That is incredible. I will do this to my JKU once my fsctory warranty expires!
60 degrees cooler without running the fan? I guess you can skip the fan and still get great results
I have a mishimoto for my JK, and it has no auxiliary fan, just uses forced air. Only down side is no cooling when parked!
I was told for performance to get biggest cooler!

we see a few jeeps in oz usually on the side of the road buggered
Thanks for showing actual temperatures showing a drop of 60 f.
I am sold and impressed with the numbers.
Damn what a difference.....
What type of electric radiator fan do you have to cool your engine?
Awesome vid and very informative. The lines that you used, you mentioned they were braided. Were they ptfe hoses or just regular rubber with braid?
Whoa my cvt on my Altima would run 240 and after the cooler it’s at 230 I changed the trans fluid and filters and still nothing tried 2 different ways to run transmission lines
But I ran the feed line into the cooler and back into the radiator
Just add mishimito universal transmission cooler
Awesome, about to put one on my 02' Accord hoping it fixes the slipping/hesitation from a stop when hot.
That won’t help your issue, I’m assuming the slipping is from the clutches going bad
@@TestDontguess it took it away completely.
Sweet jeep man, I'm adding a Hayden cooler to my Titan ,I was concerned I may need to add a fan also, may not need to. Thanks
Just added this one to my titan

Nice Jeep. Geat info ! Loved this video.
also when u install the trans oil cooler did you bypass the oem radiator
Im getting one. Im going to run them in series together.
I hate those clamps, I wish they used better hosing and proper clamps. It came with he braised line ? Or you bought those separately? Do you need to add additional ATF using the cooler ?
Where did you get your fittings to piggy back that cooler? I have s10 with a 4.3 factory cooler is not enough and need to do the same
Nice fix !!!
Now do a winter time results
Why to bother and not instal an oil thermostat?
Be nice to have some rubber mounts so it’s not so ridged of a mount .
Good job! May want to tee in your line on the return with a valve so you can use the added cooler in the summer and turn it off in the winter
How do you determine the right size of cooler for your vehicle?
Did you really hoseclamp an ptfe line???
I'm still not understanding how you run the hose I see them but I still don't know how it's ran
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? ?
If you install 2 aux coolers inline.. it will be too restrictive... Remove the factory aux cooler and replace it with a larger cooler...
see adding 40K GVW transmission cooler will do same as 25K GVW transmission cooler with fan.
Why is it bad to put the trans cooler on direct metal? Does it matter if its steel or aluminum that its up against?
Can you remember the size lines inside diameter on you arctic cat oil cooler
no idea now sorry
how about we build FALLOUT SHELTERS to fill with this product
My factory cooler is running through the radiator so will this drop the temperature of the engine coolant?
Which part number for the cooler?
It's a hayden 676. Personally I'd opt for the 697,698,699 internally bypassed coolers instead if you live in a cold climate. They're only $50 @ rockauto
What fittings are those bolted to the transmission ports on the radiator. What size are they?
Prob 1/2 to -6an
Do you see any difference in gear change
How about filter on the cooler line ?
Winter just cover up the transmission cooler with card board..
That's a big difference. Should be much happier
Yes sir, I’ve been much happier with it
how is 210 not good? when thats regular running temp for the trans
Between 55c to 70c is the best range of transmission fluid
You need to change your windshield
Large cooler and bypass with thermostat?
A transmission thermostat would be ideal for sure
i have a 2014 jeep grand i drive on the beach you think i should install it to on the beach its hotter and i you air down to 12 and drive in 1 low 4x4 ,,,,,ty i like ur video by the way
That would depend if your suffer over heating issues or high temps
@@TestDontguess well my friend just told me his temp went down to 180 in the summer driving on the beach not bad,,
Hayden part number?
yep great job, but only really good if towing or racing or heavy duty work for the transmission ,still a good external trans cooler will help extend the oil life and the transmission as well. :)
Lube is always good to get it on? What's going on here anyway?
Was your transmission overheating? I have an 08 patriot and just on normal driving on the interstate for about 35 minutes and I get a trans temp light and the car gods into limp mode.
No it wasn’t but sounds like you got some serious issues at hand if it’s over heating that quickly
funny you say size cooler to the size of application....meanwhile you go the biggest rad known to man
It is a ls swapped vehicle. The radiator is made for that purpose built according to vehicle most of the time.
i’m 100% sure that people from canada don’t need a transmission cooler at all 😂 they need an extra warmer i would say😂
That just shows how ignorant you are
Hi man , does the transmission cooler need a filter ?
Lol wtf 🤣
Isn't too cool bad?
Can I bypass the built in transmission cooler inside the radiator and use an aftermarket cooler instead?
Not recommended .run it inline... This way it warms it up on cold days... Cools it on hot days
Yes you can
I have a trans coole twice that size on my 14 tacoma...it cools about 20 degrees here in az hear ....i wont believe that little cooler will drop temps 60 degrees....lets go brandon🤡🤡🤡
