    If your mechanic says they can't do it by just removing the plenum and intake manifold, change your mechanic.

    Would there be much of a time difference mechanic should have a hoist and other gear to make gearbox way easier?

    There are a couple of youtube vids showing how to change the thermostat without removing the transmission.
    Some Kiwis did one of them.

    The method where you don't remove the transmission is really time consuming and fiddly. You won't get a good view of what you are doing. For that reason, a professional mechanic won't generally do it.
    The proper way is to remove the transmission, see what you are doing, clean the area properly etc.

    For someone in a backyard or garage with time and determination, I think the removal of the intake manifold and lower plenum is a worthwhile thing to have a go at.

    So the mechanics hoisted it and pressure tested it. No leaks. Checked the head.. Fine.. Ran it at 15psi pressure for over an hour.. Nothing.. He bled the line. I replaced the cap and so far. Hasn't lost any fluid. But.. Thermostat may still need replacing. I'll know soon enough
