    Open the hood and peak down and see if you have a second radiator between the grill and the actual large radiator. If you do, that's the oil cooler and then you have a tranny cooler because you have the towing package.

    If not then you can add one on for pretty cheap. I think my cooler was $100 Canadian doll hairs and then the dealer hooked it up for me during a transmission flush. They charged me $100 for instal. I Didn't feel confident enough to mess around with the tranny fluid.


    This is a Hayden 679 cooler. It is hooked up after the stock rad. I didn't by pass it. Temps lowered from 180f to 120-130f under normal driving, and highway conditions. It does get up to 180f on hills but I was there all the time before.

    All temps done by scan gauge

    Toyota is saying that the Trans cooler is the bottom part of the radiator

    Yes, everyone has that. If we didn't the trams would be smoked very early on. We are talking auxiliary coolers that cool after the main rad.

    The stock rad cools and heats the engine and trannsmission. Bring it to optimal temperature. However when towing it's harder to stay in this range so auxiliary coolers are added to keep everything cooler. An oil cooler and a tranny cooler.

    Sounds like you've installed a tranny cooler. How hard was it? I'd like to install one but "a man's got to know his limitations."

    The install wasn't too bad for my aftermarket cooler. I luckily had the hardware that fit sheet metal in front of the stock rad. I just used some aluminum stock and bolted it up. I had to trim some items and relocate the horns. If your cool with that the. Your good to go. It was just figuring how to mount the cooler so it wouldn't run on anything. Aftermarket coolers do come with special zip ties however I heard this can wear a hole in the rads.

    Like your self I knew my limitations and did not plumb the cooler. I had the dealer do it during a fluid change. Without a fill plug I didn't feel confident in doing it. Plus I only have to do every 100k (km) so I am not too worried about paying the stealer in that interval.

    Lets have a peek at what transmission coolers do
    TRANSMISSION COOLERS
    If you do not have a transmission cooler on your truck and you plan to tow or haul heavy loads or you are in heavy stop and go traffic and use 4X4 low a lot , consider purchasing a cooler . The cooler thats built into your rad is designed to cool the transmission with the weight of just the truck by itself .When you are in 4x4 low , your torque converter is usually in the stall stage and creates a tonne of additional heat .
    160 - 200 are considered normal temps providing your engine radiator is functioning properly . If your engine overheats , your transmission will also overheat
    Normal fluid temperature in transmission to be 175 deg. F.

    Rate of oxidation to double for each temperature increase of 20 deg F above normal (175 deg F). As oxidation rate doubles, useful life of fluid is cut in half.

    At 175 deg F life is 100,000 miles
    At 195 deg F (20 deg above 175) life is 50k miles
    At 215 life is 25k miles
    At 235 life is 12k
    At 255 life is 6,250
    At 275 life is 3,000
    At 295 life is 1500
    At 315 life is 750

    At temperatures much above 300 deg F the metals in the transmission will tend to warp, twist etc. high temperatures causes the formation of varnish deposits which impair or pre vent transmission operation.

    At a fluid temperature of 415 deg F fluid life is 30 minutes!

    Consider a scan guage [​IMG][​IMG][​IMG]http://www.amazon.com/ScanGauge-Comp.../dp/B000AAMY86
    Here is the best information for the scan guage http://www.tacomaworld.com/forum/2nd...-pressure.html

    You could also use the Torque app with an Android phone as a cheap alternative to watch your temps http://www.tacomaworld.com/forum/per...d2-reader.html

    This is how Low Pressure Drop technology works::
    When Automatic Transmission Fluid (ATF) is cold it is viscous. The unique Tru-Cool design allows the colder, thicker ATF to flow more efficiently through two open bypass channels positioned at the top of the cooler. As operating temperatures increase, the ATF becomes hotter and thinner, It's then directed through the core where it is cooled. Tru-Cool's highly efficient cooling technology combines improved protection against lube failure with optimal heat transfer.
    [​IMG][​IMG][​IMG]http://www.amazon.com/Long-Tru-Cool-.../dp/B005XZXB1M
    Long Tru-Cool Oil Coolers offer advanced cooling protection for many towing applications. The advanced technology out performs TUBE & FIN Designs, Delivers up to 15 times less flow restrictions, 30% more cooling delivers maximum heat transfer, Self-Regulating for maximum lube flow protection through start-up, varied temperatures and driving conditions, heavy loads and towing.
    Here is Toyotas fluid flow guide ...Look at page 8 on this PDF http://www.toyotatundraforum.com/pdf/A750E.pdf

    Thanks Taco16. Looked at my radiator and the A/C cooler occupies the entire space in front of the radiator!!! There's no room in front of the A/C cooler either. Oh well.......

    Calleboy did you find a cooler? What brand? Where did you find space to install it? I can't find any space. Thanks!

    Edit: if you installed one, was it hard to do since the lines are 3 yrs old at this point? I also have a '13 2.7, but mines a Prerunner. Worried about connections being corroded.
