    You'll need to buy a Ford or Chevy, or Fiat to visit the Maintains. You'll go there a lot :)

    Those of you that have done the install. Approximately how long did it take? Any tips or tricks much appreciated.

    Any tips on install of the hard lines would be appreciated. Feed starting from the thermostat side and twist and turn working forward? Any dos or don’ts? Thanks!

    I never read anything about it but I had to remove the skid plate to do anything.

    I did remove the skid plate, made attaching the rubber hoses easier. I ran the hard lines from the back to the front, and actually didn't have much trouble, believe I kept them closer to the engine side. Does require some twisting to feed them through, for me starting the front bolt was the hardest part of the hard line install.

    Put electrical tape over the hard pipe holes to stop dirt entering the pipe as you push it through. Start from the back and work forward and dont force it. I never bothered removing my skid pan. If you already have the the cooler in place with bracket it will take 1.5 to 2.5 hours depending on your skill.

    How did you attach the hoses that go the cooler to the hard lines with the skid plate on, your way more talented than me, lol. I took one look and took the plate off.

    Getting the truck level and adding fluid took me longer than the install

    I pushed them on from the top. A little ATF and some swearing got them on.

    Does anyone know at what temperature the high transmission temperature fluid warning pops up?

    I was searching for this on other forums specific to Toyota and Lexus and it looks like 275. But that was a Lexus forum...

    Just towed my 7000lb travel trailer 2.5 hrs to a camp site , box loaded with fire wood and supplies , 4 adults in the cab , plus a head wind . Fuel mileage took a major dive and trans pan peaked at 210 degrees . But usually sat around 200 to 205 the entire trip . Very happy with this new cooler setup

    Glad it's cooling well for you, but it sounds like you are way over payload. Don't get me wrong, I'm not a nazi about it and being a little over isn't the end of the world, but this sounds like it's way over. Did you scale it by chance?

    Were you driving in 4S? I'm curious what your gas mileage was with a heavy load like that.

    He's definitely way over but most are if you plan to use it like a truck. Just the four guys and firewood would have put him over.

    Any idea what size O-rings for the Tstat housing ?
    I just found one on ebay for $81 but need the orings for it.
    I already have a nice oil cooler I can use and it even has a t-stat controlled fan mounted to it.
    All I had to source was a few hoses and the steel lines to slap a kit together.

    I would definitely have gotten a kit from OP if I didnt already have stuff here to do it.
    Looks like a very nice, well thought out kit.

    I only paid $83 off Ebay for a new thermostat. It came in Toyota packaging and it comes with the O rings.

    Your spacer will have O-rings that you will no longer need that you can use.

    How is this compared to a similar run without cooler?

    Back from our lake vacation and very happy with Nick's tranny cooler kit.

    We left home headed north with ambient temp at 94*F, boat hitched up (around 4500lb), rear seats up and area filled with stuff as well as truck box. I drove in S5 with A/C on and tow/haul engaged, for the first 110 miles on the interstate at +/-70 mph. Transmission pan temps mostly 199* and 200*F, I did see 201* two or three times only for a moment. Engine coolant temps stayed mostly in the 190's.
    We got off the interstate for the last 60 miles of two lane highway with mid 60's mph speed, pan temps fell to mostly 195-197F range.

    Return trip saw cooler ambient temps, 75* to start and about 80* by the time we were home, did not use A/C, pan temps mostly mid 190's, as well as both engine coolant and engine oil temps. Although not related to this thread, I installed black SumoSprings a couple days prior, and they are just fantastic!

    Thats awesome. A lot of people were worried about my bracket blocking the radiator to cool the engine down but I have not seen any reports of high oil/coolant temps.

    Ya I saw some concerns from people about that also, but after my experience on this trip I don't think there's anything to worry about.

    The bracket may have a minor impact on overall the air velocity, but it has zero impact on the pressure differential. The black shields on each side act as an air dam to increase positive pressure to help force air through the radiator. Air, like water will flow the path of least resistance. In this case it is through the Radiator fins (for the most part). Technically speaking, each grille trim level should have a slightly different flow rate as the surface area inlet and radii around the openings is different but since the bottleneck for flow is through the radiator, the impact due to grille trim variations or a trans bracket for that matter is negated or negligible at best

    Yeah most likely over payload but I wouldn't say way over . I'm thinking a couple hundred lbs over . Have not had a chance to weigh the rig yet

    I towed in s5 with the a/c on most of the time. My fuel economy was 34L /100k . The head wind killed me this time . Usually I get 21 to 24L per 100km when towing . There was also more rolling hills where I went camping this time
