    Is the general recommendation to just pin the thermostat and run with it pinned as a permanent solution?

    My recommendation- pin the thermostat and monitor the transmission temperature. If it stays most of the time in 170-180 and below and only occasionally go up to 195-200 You are good
    If you see most of the time in 200 and above, go for the cooler.

    But is is mine opinion for whatever it worth.
    I gust know the older gens of 4runners dont have any thermostats and i never heard about the transmission problems. Not saying there are none, but not many for sure.
    My 2009 sr5 4runner with 245,000 miles I never saw go above 165-170 without any cooler. I change ATF every 60K miles.
    My $0.02
