Auto Transmission fluid

I use Dexron. Chrysler has company videos dating back to when these transmissions were sold to the public on YouTube warning against using a type F in a Torqueflite. Coolant doesn’t matter, just don’t use 100% pure antifreeze. It will make your engine run 15 degrees hotter than it should and makes vapor lock issues worst using today’s fuel in a carbureted vehicle.
Your engine will run several degrees cooler, using 100% water. Compared to 50/50.
100% distilled water in summer, swap for 50/50 in winter. Just don’t forget to drain water near the end of fall time on east coast.
