new engine might already be experiencing "blow-by".
search for a manual and check compression values. then have a mechanic perform a compression test on your engine. if result is much lower than expected, then try replacing piston rings, valve guides, and valve seals

Previa heaters are usually ultra-reliable.
So, regarding your question, the only reason for the temp gauge to drop down with the heater on is the thermostat is sticking open, or you have a lower than recommended thermostat installed. The factory thermostat is a 192 degree F/89 degrees C stat. Down your way, a lot of the parts places vend the "summer" thermostats, and I suspect that this is your problem.
Look to see what the temp degrees that are printed on the stat. Should be 192 F or 89 C. The "summer" stats are 185 F/ 85 C. Also, make sure that your stat has a small "wiggle valve", some aftermarket stats do not have this. Very important. Install the stat with the "wiggle valve" pointing straight up/12 o'clock...
Regarding your trans dropping out od OD, this is because the coolant temp is dropping below 172 degrees F. This is the threshold for the OD to engage. Below 172/no OD engagement.

The rear seats have 1 x12mm or 13mm bolt securing it to the rear wheel arch.

Remove the cover over the bolt and unbolt the bolt 12mm or 13mm on the left and right side wheel arch

Then under each seat is a metal clip that holds the seats in place lift them up to unclip the seats, and then they can be removed.

Have to fabricate what is rusted or broken

You can not buy new parts at a dealer after
10 years & on most cars not at all ever

Just as you would repair or replace brake or
power steering tubing

Some online as well as auto parts stores have the
end connectors if needed
