    Price $890 with free shipping to the lower 48. Canada, Hawaii, and Alaska will have an additional charge.

    *** Fits only 2019-2021 5.7L Tundras with a 2018+ grill ***

    I sell complete transmission cooler kits for the 2019+ Tundras. As some of you may know, the 2019+ Tundras do not come with a transmission cooler. Instead, they have a heat exchanger that uses the hot coolant from the engine to try and cool your transmission. It is not effective and many people while towing have received warnings for high ATF temperature (warning comes on at 302°). The kit I sell will come with all genuine Toyota parts from the thermostat to the lines that run to the cooler. The bracket is custom designed to fit right behind your grill for max airflow while utilizing factory threaded bolt down points on the vehicle. Once the kit is installed, expect ATF pan temperatures to be between 185-205 degrees depending on ambient temperatures and your load (with thermostat not pinned open). Pinning the thermostat will yield cooler temperatures as the thermostat is bypassed. This will allow ATF to flow at all temperatures.

    Parts Included:

    x1
    Hayden 778HD Transmission Cooler
    x1 Hayden 778HD Bracket (powder coated gloss black)
    x1 Horn Relocation Bracket (powder coated gloss black)
    ×1 Horn Ground Cable
    x1 32970-34030 Transmission Thermostat
    x1 32941-0C030 Inlet Hose
    x1 32942-0C040 Outlet Hose
    x1 32907-0C020 Cooler Pipe
    x2 90080-10400 Cooler Pipe Bolts
    x8 90466-16004 Hose Clamps
    x2 10AN O-Ring Boss to 6AN Male Flare Adapter Fitting
    x2 6AN Push Lock Fittings (color black)
    x1 Transmission Cooler Hose x7'
    x4 High Temp Cushioned Hose Mount Clamps
    x2 Synthetic Grommets (for wind deflector)
    x2 Toyota WS Quarts (pump needed)

    - All Stainless Steel Hardware

    Tools Required:

    - Socket Set (Metric)
    - Allen Keys
    - Pliers
    - Step Hole Drill (1.25") Amazon sells cheap ones for around $11.
    - Hose cutters or sharp knife
    - Hydrophilic Jack and Stands
    - Level (For ATF Check) or someway to verify your truck is level

    How to Buy: message me here with your email address associated with your PayPal and ill send you a invoice... or email me at chasenicholas93@gmail.com

    Instructions: Bottom of the page.

    How to Monitor Temps: Cheapest option is to buy the app "OBD Fusion" on your phone and input the custom PIDs for the pan and torque converter temperatures (see below). You will also need the bluetooth OBD adapter. There are many brands but here is one of the cheaper options.
    https://www.amazon.com/Veepeak-OBDCheck-Bluetooth-Diagnostic-Supports/dp/B073XKQQQW

    In order to input the pan and torque converter custom PIDs on your OBDFusion app go to "settings" then "User-Defined PIDs". Copy the information below. Leave everything the same besides what I am telling you to change.

    ATF Pan
    Name: ATF Pan
    Description: ATF Pan
    English Units: F
    Min Value: 0
    Max Value: 300
    OBD Mode: 21
    PID Number: 82
    Equation: ((((A*256)+B)*(7/100)-400)/10)

    Torque Converter
    Name: Torque Converter
    Description: Torque Converter
    English Units: F
    Min Value: 0
    Max Value: 300
    OBD Mode: 21
    PID Number: 82
    Equation: ((((C*256)+D)*(7/100)-400)/10)

    Don't mind the blue fittings in the pictures. The fittings I provide in the kits are black.

    Could be the picture but it looks as if the bracket blocks alot of airflow too all of the air to liquid coolers.

    It's a small cooler and the wind shield still deflects air behind the mount. Additionally, the cooler is about 6 inches from the radiator. This design allows for maximum airflow through the grill and will not interfere with the other cooling systems on the truck.

    You should do a complete kit. Get everything together and sell it for one price. I would buy one his summer if the temps on my 2020 are higher than expected when towing my TT.

    Honestly, that is not a bad idea but most of parts you need come with free shipping so it wouldn't be worth if I can just provide you guys with the parts I used.

    It would be a good idea with the hose. The biggest pain was finding the correct length for the hose and hose heat protector. That would save you guys half the trouble.

    Lots would just want to buy a complete kit and not want to spend time searching and waiting for parts to arrive. It would be nice to have a complete kit so the buyer could just install and go. Add instructions on the installation and you could have a hit.

    Lol. I think you might have gone just a tad big on the size but at least you have more than enough cooling capability.

    Got the hard lines installed from Toyota. A pain in the ass but a more clean install.

    Just figuring out how to get it in there. You have to twist it a few times, it's like a puzzle.

    In that 2nd pick I'm guessing that's the two factory in/out hoses to the thermostat, if so is that gold bracket one you added to stabilize those two hoses? I don't see it listed as a part.

    I need to update the post with the OEM Toyota parts. You will just need 2 adel clamps for the back of the mount.

    Just gonna let you know that I d/l the 2015 service manual and the listed torque values for the atf warmer/thermostat (3 bolts) is 15 ft.lb.

    How do you find out if you need one of these coolers for your truck? I have a 2020 and pull a 28ft camper sometimes in the summer. I live in Texas and the heat is pretty bad here.

    It's not proven it is "needed". According to toyota it is not needed, however, if you monitor your temps while towing your camper you will probably think else wise.

    LED headlamps/fogs; interior footlamps.
    Get an inexpensive odb2 BT and an app like Torque Pro ($5) or other favorite transmission temp reader.

    Might want to consider trans fluid drain/fills at motor oil drain/fill timeframes....just a thought...

    What temp does it start to wear on the transmission?

    The higher the temp the faster the ATF breaks down its lubricating properties. Transmission wear is inevitable however, having the ATF at a lower tempature will prolong the fluid. Some charts show an increase of ATF around the 250° range will cut the life of the fluid in half over time. Additionally, I have read clutch pads break down under high temperatures.

    If you decide to buy a obd2 and temp app could you please report back what temps you see towing your camper?

    Greetings,
    Still piecing together the stuff to install the cooler. In your parts list you specify a 45 deg. push lock adapter. The one in your picture looks like a 120 deg adapter. The m/f adapter is a 45 deg. As it stands now, it appears Toyota would deny warranty on the transmission if I do this. (What a rip!). I may do it anyway however.
    Regards,
    Boyce

    Thank you for catching that. You are correct they are 120 degree push lock adapters.

    To me it was worth it. Just piece of mind knowing my temps will stay much cooler than stock.

    Looks like a very nice setup - well done! Typically lines enter bottom or side (lower is inlet) on cooler to fill cooler and push air out to remove voids. Why lines on top?

    Most trans builders will tell you, trans fluid operating temp around 180*F will significantly improve fluid life and trans reliability. Well done getting fluid temp down to 190*F.

    For the masses - Yes, full synthetic fluid does holds up much better to heat these days, however trans seals don't. Pressure loss issues are the beginning to the end of a trans clutch pack or band.

    Interesting. Gotta appreciate a cool running transmission.

    Side note - The pressurized fluid fills the cooler pushing the air out. Ford full size cooler lines all enter on bottom. GM side tank radiator with cooler - fluid enters bottom to push air up and out. Engine cooling system coolant inlet is at the bottom to fill voids with coolant and eliminate air pockets. Just a thought (not that yours isn't working).

    I just want to throw my 2 cents in here , In my opinion if someone tows alot just leave the truck stock , don't mess with modifying it to have a cooler and risk the chance Toyota denying you warranty if something were to shit the bed . just drain and fill the trans yearly with Amsoil Signature series Trans Fluid , its the best synthetic trans fluid on the market for holding up to extreme heat , I find that to be a simpler solution imo
