Hello all, long time lurker, first time poster. Great information in this thread which helped me a ton with the install.
I went the DIY route for mounting as brackets are a bit difficult to come by in Canada. Slotted steel 14 gauge, 1 3/8inch wide, one piece across the bottom angled through the existing holes, and a second for stability over the horn using the OEM horn mount to secure. I pushed the cooler farther out in front of the radiator/horns to maintain the OEM horn positioning. It is very sturdy and I'm happy enough with the aesthetic.
Hayden 678 kit cooler and tubes. I routed the radiator to the lower connection and the transmission to the upper connection. Maintained the OEM spring clamps in their original positions, and used fuel injector clamps at the cooler. In theory these should result in a more even tension distribution than hose clamps. 1/2inch braided sleeve over the tubes for some protection, a bit tough to get a clean cut but it will do the job. I read heating up prior to cutting helps but laziness got the better of me.
I left the bumper/grille installed and just worked from above and below. Disconnections/connections were tight but was doable with an 11inch bent nose plier.
Didn't bother with a fluid exchange as I did two drain and fills 10-15k KMs ago. Filled the radiator and tubes with ATF before completing the connections. These 3d printed plugs (not my design) in PETG helped keep the cooler/tubes filled while routing but I did see GX Bob uses screws which would've worked just as well Transmission Oil Cooler Fuel Hose Line Plug 10mm ID Toyota Tundra by balancepnt - https://www.thingiverse.com/thing:6819393

my setup looks almost identical, except I put rubber washers on any metal-metal contract to reduce vibration.
What type of pin are you guys using to pin the thermostat? I’m about to do my trans cooler install. Thanks
lol just asked about thisPin thermostat open with 1.5mm pin and idle until AT Pan temp is 115-126° in Fusion before removing overflow plug (one more new crush washer needed) to set ATF level.
Check. (and leave stat pinned open in my case)
I just used a thin nail I had laying around. Prob should have used something more secure, but the spring tension of the thermostat holds it is place.
+1 just pin the thermostat
A much better option!+1 just pin the thermostat
I’m at Home Depot right now getting rubber washers, I’ll pick this up! Thanks!+1 just pin the thermostat
Looks like Lowe’s has the Hillman pins in stock
Yep! I had 8 of them delivered in March. But I unpin it for winter when I do my Fall oil change. About time to do Spring oil change and repin it open with a new one. Reused the heck out of them growing up on tractor and wagon hitch pins and other things, but for some reason I want new ones on the GX LOL.
That is what I did. I had a nail that fit really well, bent each end like a cotter pin and it's been fine for well over a year.
I just used an allen key from my allen key set lol. It's even got a convenient bend on one of the sides.
I though about it lol
