I have 2007 4runner, mounted my transmission cooler behind front bumper crash bar with homemade aluminum bracket and 3 heavy duty zipp ties. I wanted to have space between the cooler and radiator for more air flow. My original intention was set-up to pull a Casita 17ft. travel trailer. Also added a screen for rock and bug protection using gutter screen, edged it with rubber and Zipp tied in place.
Recommend an in line transmission filter (steel magnifine filter) for a little added filtering. I added one to an older vehicle with 150k miles and the more i drove the more difference it made in shifting smoother. Great video btw.
I thought about an in-line filter, but I dismissed the idea because I did not want the potential of failure or clogging on the cooling line. I do a drain and fill once a year on the 4runner. The fluid gets changed often enough to remove contaminates. It's cool to hear that a filter had a positive affect. Thank you for sharing, and thank you for watching the video!
I am concerned about adding one because I will be running a Victory 4X4 winch bumper with a winch in front of the radiator and will have additonal skid plates to block even more air. I do intend to change all non-motor oil fluids at 25,000 mile intervals since I tow here and there and do off roading. Nice video.
All the more reason to add one in my mind. When you add a winch and armor the lower portion of your radiator is doing less. Turns out the factory transmission cooler is in the very lower portion of the stock radiator. I'll also be adding a winch soon. So I can report back about how temps are affected. Just as a thought, if the transmission is kept cooler, than the main radiator should have a bit less work to do. Since less heat from the transmission is being forced into the main radiator. Thoughts? When it comes to fluids. I'm planning on doing the same. With the amount we drive and tow, i'm just going to change all those none-motor fluids about once a year or so.
@@EmbarkWithMark Thoughts are people expect crazy fluid interval changes, not me. Oil is cheap, new engines and transmissions are expensive! I just sold one of the best set-ups for towing there was, it was a 2013 F-150 with the HDPP package, so everything was upgraded, springs, shocks, coolers, steering, towed through the mountains and everywhere else in the southeast and the trans temp stayed the same, whether towing, if it was 40 out or 98 degrees, it was always 195-204 basically. Obviously that set up worked really well to maintain such a great similar temp in nearly every condition. But it didn't have a winch or skid plates. I may get a temp gauge and monitor how it handles temps as I add these things and then figure out if I need one. But it's not a bad idea to add one sooner either, that way, I only do the install once.
Mark, did you have to re-program the Ultra-Gauge to get transmission temp reading on your 4Runner? I purchased an Ultra-Gauge and mine will not read transmission temp.
I had to program the transmission gauge in. It's an "mgauge" If I remember correctly. Here is where I got my info for the gauge setup. My 5th gen is a 2015 4runner so you may have to look up something different if you have a newer year. But this will give you a good starting point. www.toyota-4runner.org/5th-gen-t4rs/260737-ultraguage-mx-transmission-codes-2016-sr5-4runner.html
I was wondering, you used the output from the stock transmission cooler into the new added one. Was that the directions from that particular manufacturer and style of transmission cooler. I've seen another install and they utilized the input into the stock transmission cooler. Confused fellow 4Runner owner. Thanks
So, there are two schools of thought. I’ll do my best to explain. The stock transmission cooler is part of the radiator and will warm the transmission fluid up to operating temperature when cold outside. But also does not cool as well since the radiator is sitting at the same temp as the engine coolant. Going from stock cooler to the added cooler than back to the transmission gives you maximum cooling. Going to added cooler than to stock than to transmission will still cool the fluid, but the fluid will get warmed back up to the temperature of the stock radiator in your vehicle. For us. I opted to go for max cooling. Since it routinely hits 120 here and we have grades that take us to 10,000 feet. Plus we tow a trailer. One word of caution if you live in a colder environment, in the winter you may need to use something to block off the added cooler to get the transmission warm enough to operate correctly. With the cooler I installed, I’ve not had to do that yet.
Thank you very much, I appreciate it. I'll follow the installation that you did. I do live in the cold northeast and will cover it for those colder snowy days. Again thank you.
I'm not following what you mean. I ran the transmission line to the radiator, then the external cooler, then back to the transmission. Are you asking to go from the transmission to the external cool, then the radiator, and then back to the transmission?
@EmbarkWithMark I have a 07 runner RWD and I am in fL. I dont do no towing nor heavy load but just adding it for the longevity of the transmission. The radiator column to transmission fluid is on the driver side. I wanted to know if it's a safe run give it that double cooling feature for a non tow package?
@@doobedi You really don't need it if your not towing or loading the 4runner down. But, if you really want to add the aux cooler, it wont hurt anything. Though, you could run too cold in the winter depending on your climate. If the transmission does run to cold you can just block off the aux cooler. That's what I do in the winter.
Im thinking of adding an external transmission cooler to my 2019 Tundra, which Toyota did away with. Im a novice, but it looks doable. Being a novice, im wondering if the trapped air in the newly installed hoses and cooler are no issue? Its the Tundra, so the external cooler will be independant of the current heat exchanger warmer thats already part of the system, and therefore require about 12 ft of hose length from transmission to the add-on cooler and back. So i was curious if the air in those hoses were not a problem ?
Trapped air in the hoses shouldn’t be an issue. But the cooler could trap air. Buy a good brand cooler and the instructions will tell you which way to place the cooler so air does not Become trapped. Installing a cooler seems daunting, but if you take your time you will be fine. Hope this helps, good luck!
@@EmbarkWithMarkok, thank you for your response. Ive purchased a Hayden cooler that looks very similar to the one in your video, but slightly larger. Thanks again.
What settings did you use on the UltraGuage to display the trans temp? To confirm, are you running the MX? Trying to figure out a similar config for my 21 4runner seems like no out the box support without customizing for the trans temp.
There’s a code for Toyota 4Runner transmission temp that you put in. I’ll try to find where I found the information later. And yes I believe it is the MX. setup takes a bit. But once you work through the process, you’ll see how awesome it is.
Scan Gauge II was plug and play on my 2017 4runner. You can set a alarm to notify you if your trans temps are getting past a set point too. You can monitor pan temp and converter temp at the same time. You can also see if your torque converter is locked or unlocked. I love it for towing.

Did it work? What is the temps now?
Absolutely! Helped a ton. Normal temps are 140-150 usually and that’s on hot days ( 110 plus). Naturally the towing temps are way better too.
