    Does anyone have any pictures they could share of the routing for the OEM hard lines on the tundra 5.7’s? I just received mine and trying to figure out where exactly they route to the front of the truck?? TIA

    This will help you figure out the routing.

    I haven’t gotten to the install yet but was thinking the same question. Thanks Dave!

    NP. When I first installed the hard line I never bothered looking for the diagram and it was frustrating finding the rear mounting hole for the pipe. It's lower than you think.

    Off hand does anyone know if this transmission cooler change affected the Landcruiser? I searched around but couldn't find anything.

    The Landcruiser received an a 8-speed transmission all the way back in 2015.
    I suspect it is a (AA80F) variant . The Land cruiser also has lower towing capacity ratings.
    the Tundra is a 6-speed. (AB60) transmission.

    Thanks...saw that after I posted.

    However it looks like the GX 460 has the 6spd and it offers transmission cooler as an option.

    Outlaw exhaust, cai, scangauge, tint, nerf bars, soon to be trans cooler.
    Finished my cooler install Friday night currently running the stat pinned open and my temps stay around 167 to 170 cruising 65 to 70 mph with the ambient temperature of 90 degrees plus.

    Much thanks to all the people who took the time and researched the part numbers and found the diagrams, you made this install so much easier than i thought it was going to be.

    Sorry for the wait everyone, I decided to just order the parts to complete these kits through Roman. I expect to start shipping kits in no more than 1-2 weeks.

    So I started monitoring temps via my Kenwood headunit. Normal 30 min drive to work it heats up to 205* +/- 5*. I pulled a light trailer (~1000 lbs) this weekend for an hour at varying highway speeds up to 75 mph (in S mode 5th gear) and saw 230* at its highest. Not happy with that, but I also don't think that I should spend my money and time to fix this. I'll be communicating my displeasure through every channel at Toyota that I can. Wish me luck!

    Totally agree with you. I will drive my new truck and monitor the trans temp until the trans explodes. then get it covered under warranty / extended warranty until it explodes again, and continue this until Toyota gets the point. I tow a 6k TT, so we will see how it goes. Headed out on my 1st trip with the truck and TT in late August. I will see what my temps are.

    Interesting anecdote for this thread...New Ram trucks are in a similar situation. I have a very close friend whose Rebel is hitting 248-250 F on the engine oil temps. The alarm point is 265F. Engine coolant temp is based off a 203F thermostat and the thing normally runs 220F unloaded. Searching on Ram forums this is a recent phenomenon and many folks alarmed. Although...the trans temps barely creep over 200F pulling max load in 98 deg weather.

    Looks like OEMs are pushing higher temps in the working fluids.

    That is interesting , Its the never ending struggle to squeeze out another mpg from these trucks .

    In my experience, accounting and finance does cost/benefit analysis and submits it to the corporate operations managers, usually engineers, who ultimately make design decisions.

    You rarely see accountants as CEOs or COOs. Usually engineers with MBAs.

    Toyata bean counter isn't dumb (otherwise they wouldn't be a bean counter). your transmission isn't going to go bad till AFTER the warranty is over.
    since Tundra transmission can currently go 250k miles towing ? it probably just mean it is now a 120k miles transmission (when towing), well outside warranty and extended warranty.
    note that very few Tundra owners tow anyway. so I doubt anyone is gonna have transmission repaired under warranty due to heat.

    250F is nothing for a synthetic engine oil. synthetic engine oil can easily tolerate up to ~290F without losing significant properties.

    fyi, so you don't feel too bad for not having the cooler .... i was talking to a co-worker about this issue and he knows this fishing guide with one of the Tundra models that didn't come with towing package and no trans cooler ... He got the hitch at I think U-Haul (no trans cooler added) and has been towing his boats practically 3 to 5 times a week for years and over 360K miles with no trans issues. He has 3 different boats from a drift boat , river jet boat and a big salt water boat over 6000 lbs.

    He told me many Tundras come with no towing package (i.e. No trans cooler) and are towing since people add their own towing hitch. I have done that with 2 cars in the past and about doing it with another car. I got my last hitch at U-Haul for a 6 cyl car. They did a very nice job but other than that u-haul doesn't install cooler.

    Pulling a boat is not a challenge for a Tundra compared to a TT. Toyota has used a cooler with all their tow packages for the last 11 years. I find it hard to believe they just discovered a cooler wasn't needed. Toyota's engineers in 2007 did the testing while towing and found a cooler was needed while towing.

    Has transmission fluid spec changed since 2007? Has it always been Ws?

    Just a thought, but has anyone done some towing on these trucks without a cooler and had the transmission oil sent in for analysis? Is there any data to show that the current set up is actually a problem waiting to happen, or is all the worry based on the charts and such stating that transmission oil breaks down at X temp?

    No need for me to send in my oil. 250F is just too warm and this wasn't even on a hot day or working the truck that hard. I vacation in the maintains and climbing a long grade my temps would easily go north of 260F. My temps are now at 170-180 without towing as compared to 220. Regardless of the "chart" it's common knowledge that a lower transmission temperature increases the service life of ATF. Heat is the number one killer of automatics.

    I hear you. I was just asking if analysis had been done.

    I've done service work on Senna transmission and was very surprised to see how dark it was with only around 40K. I would have loved to analysis it.
