Overcooling and torque converter difficulties plagued the Acura Integra in 1989.

As stated in the title, I own a 1989 Acura Integra LS that my grandparents purchased new and passed down to me. I drive it on a daily basis and would like to preserve it in good operating order for sentimental reasons as well as the fact that it is a lot of fun to drive.

It's had an overcooling problem for a while, which we were able to partially resolve by replacing the temperature sensor, thermostat, and radiator. We didn't see any improvement until we installed a "cold weather" thermostat (we live in florida). This, I believe, has something to do with the following issue.

The torque converter frequently engages and disengages once the car warms up, which is a more recent problem. Though it never quite heats up to the point where it should, my theory is that it is disengaging the torque converter because it isn't fully warmed up, and then warming up just enough to engage it, causing it to cool down and disengage.

Outside of what I've learned from my father, who is an excellent mechanic (but is now too old to undertake the task), I have virtually no experience or knowledge of automobiles.

That's not how torque convertors work. They lock up with an increase in fluid pressure relative to rpm and engine load. What do you mean by "overcooling".
