    Some may have seen my post that I'm considering getting a camper to haul with my '09 dclb v6 4x4. I saw one youtube video where he installed an upgraded cooler and it significantly reduced the temp (180 - 120).

    Has anyone installed one? I think he installed this one. I'd assume all I'd need to do is move the inlet on the main one to the upgraded one and the outlet from the upgraded one to the inlet of the stock cooler.

    I would replace the factory cooler with a single, larger unit. Less plumbing to leak. I did so recently as part of a major cooling system overhaul (replaced all the factory lines etc. with stainless braided hose and aluminum AN fittings at the trans) and replaced the factory cooler with a much larger Hayden unit, although you don't have to go quite that far if your factory lines are still in good shape.

    I was looking at Mishi coolers and don't have anything bad to say about them necessarily, but the Hayden is designed to partially bypass the trans fluid below operating temps, which is a huge plus if you live in places where it gets very cold - helps get up to temp faster.

    Years ago, I installed a dedicated automatic transmission cooler. Disconnected and no longer use the oem trans cooler in the radiator or the optional towing package trans cooler for transmission fluid cooling.

    Radiator cooler is capped off.
    Oem optional trans cooler became a power steering fluid cooler.

    I isolated each so there was no chance of having a radiator failure pollute the transmission fluid.

    I ran a b&m take off cooler. It had a fan with a thermostat controlled switch. Did the atf flush & filter at the same time, a mistake. Apparently the clutch packs were badly worn so the clutch material in the fluid is what was making it not slip. Contemplated my options, went ahead with the rebuild. The next day I rear ended a new Mercedes in the rain. The end of me in a vehicle without abs.

    I installed this cooler 8 months ago, it doesnt really do a decent job in keeping trans temps down when compared to the factory cooler. Which is why Im here, searching for a better cooler which is going to be B&M style. I monitor my temps with a Bluetooth App and aftermarket trans temp fluid gauge. My Mishimoto Radiator and C7 Corvette/Camero Electric Fan combo does a superior job with keeping the coolant system stable when its slow going up a trail at altitude or in high outside temps. I wish tue Mishimoto Trans Cooler could do the same.

    Here's the install info with pics https://www.tacomaworld.com/threads/monkeyproofs-misadventures.697489/page-7#post-27835139

    Heres a pic from a recent trip to Death Valley, notice the Coolant Temp on the Bottom and Trans Temp at the top. Outside temp was 90-ish going up a long incline with tires aired down. This recent trip that had me decided to find a better cooler.

    There was a recent thread where the dude simply moved the oem cooler upwards about six inches and had hard data showing cooler ATF temps. Moving it up puts it in more direct line of airflow.
