    I've designed a transmission cooler bracket for the 2019 - 2021 trucks that don't have a transmission cooler from the factory. This is a budget friendly way to piece together your own kit. This mourning bracket utilizes already existing holes/threads.

    A PDF below contains the part numbers for the other parts needed as well as installations tips. I ordered my OEM parts from one of the online dealers and was able to get a discounted price and free shipping at the time of my purchase. They are also available and eBay and other places online. I have seen sellers on eBay that have the thermostat, inlet/outlet hoses, and hardliners bundled together in one listing for a good price.

    The bracket uses the Hayden 679 transmission cooler which doesn't require any extra fittings for the 3/8" hose to connect. I've pieced together a stainless steel hardware kit to go along with the bracket.

    Included:
    -Custom plasma cut mounting bracket made from 12ga steel for Hayden 679 transmission cooler powder coated black.

    -Stainless Steel hardware kit with necessary hardware to mount the bracket to the truck, mount the cooler to the bracket, and hardware for horn relocation.

    -(2) Rubber grommets for protecting the hose that connects the cooler to the OEM Toyota hardlines. Requires a 1 ¼" hole to be drilled in the passenger side radiator wind deflector. I used a step drill bit for this, I’m sure a hole saw would work as well.

    Cost:

    $130 for a mounting bracket with a stainless steel hardware kit. Free shipping for forum members ordered via PM.

    If you’d like to save a few dollars and paint or powdercoat the bracket yourself send me a PM. I often have some available.

    In an effort to make it easier for everyone and more reputable, I’ve listed these in an eBay auction:

    @Jmunk, interested in the powder coated bracket with the hardware. I could go ahead and pay for it now and you could ship it out when you get it in. Please send me your payment requirements. Thank you!

    I have a batch of brackets back from the powder coater. The cost to powder coat was less then his initial quote so I reduced the price to reflect that.

    I do have a bracket that managed to get a scuff in the powder coat. If anyone wants a blemished kit send me a message. I can offer it at a discount.

    I found an additional photo and uploaded it to show hose placement. Someone else may experiment and find a better option, this is just one option.

    Glad to hear.

    I’m down to a few brackets with some light scuff marks. I had the fab shop cut one more batch, they are currently getting powder coated. Unless the demand is high, this maybe the last batch. Once I get them back and listed I’ll update the thread for those that wanted one.

    The powder coat shop did a nice job. Now that I established a good power coat business I can see me getting various things done for better longevity.

    I’m waiting for a Hayden 689 cooler to arrive this week. If the mounting holes are the same as the 679, which I believe they will be given the coolers are the same size then this will give an option to use the 689 cooler and get 90 or 45 degree fittings like below for straighter lines.

    https://www.jegs.com/i/JEGS/555/110...e00PEWskfWzD7BExMUw1aQKBu8oKxWKBoCeOIQAvD_BwE

    I think most would rather stick with the 679 given the 3/8” barbs are on the cooler already and you don’t have to buy the two extra fittings. Just another option is all. Once I verify fitment on the bracket I’ll update the thread.

    The Hayden 689 does share the same bolt mounting holes as the 679, it bolts onto the bracket I made. The one caveat is that the 689 uses -6an fittings to thread onto the cooler and the wrench flats on the fittings provided has to be flat and parallel to the bracket for it to fit without making contact. With the variety of fittings manufacturers out there, it’s hard to say if all fittings brands would fit without interference.

    If I made another batch of brackets I can change the CAD file to have the small area of interference cutout. The area of interference is about 1/8”.

    If anyone wants to purchase a raw finished bracket and use a Dremel or like item to clearance the bracket for the fittings let me know.

    Overall, the 689 allows for angled fittings to be used for a straighter run with the hose. It does come with (2) straight fittings from Hayden. If you wanted angled you’d need to buy those separately.

    The 679 already has the correct 3/8” hose barbs and just requires some turns in the 3/8” rubber hose. Both work fine, just personal preference.

    What did you do to the tab next to the upper bolt that fixes the horn? I blew a hole with plasma in my DIY bracket, otherwise the bracket does not sit flush.

    Anyways, looks good!

    If you asking about the top mounting bolt, I use a spacer between the bracket and the truck so it’s straight.

    Thanks - I enjoyed the process of designing and getting them made. I will say that everything turned out nice and the powder coat finish looks great.

    For anyone wanting to save a few dollars and get a raw steel bracket to paint or powdercoat on their own send me a message.

    I’ve started taking my measurements from the Hayden 689 and the fitting clearance issue mentioned above and working on the CAD file. I should have one of them cut and in my hands in a few weeks. If anyone wants to use the 689 cooler let me know and I can keep you posted on the progress. I’m also working on getting a good supplier for the AN fittings require.

    This is a great product from a great seller! I received mine in less than a week from the time I ordered. Everything is well packaged and all the hardware is labeled which is a bonus. I sourced all my oem parts for my trans cooler with a Hayden 679 cooler and installed it about a year and a half ago. I did make my own custom brackets that worked well but this bracket is top notch.

    Old bracket haha

    Looks great! I’ve spent the extra money on the stainless hardware and spacer. I’ve made sure to used good quality components and not the cheapest.

    I hope you found the installation to be quick and painless. Let me know if I need to make anything more clear in the installations tips.

    I do have a batch of brackets at powder coat for the Hayden 689 (will also fit the 679). Once I get those back and the required AN fittings I will offer those.

    I think the bracket and Hayden cooler combo works well and surpasses the transmission cooling capabilities of the earlier years with OEM coolers. Great way to get it done for much less than some other options, especially if you buy the OEM parts in a bundle from one of the eBay sellers.

    Thanks again for sharing the photo!
