The car is a '54 sedan with it's original powerglide powered by the original six. Long story short, this is the second heat exchanger to rust out and dump all of my coolant. My plan now is to run a radiator type fluid cooler but I would really like to just remove the cooler completely for now so I can drive it for a while until I get a new cooler. Is it safe to drive the car without any type of trans fluid cooler? I don't plan on going on any long road trips and I drive it slower than my grandmother, but I would like to be able to go drive somewhere about an hour away and still have a working transmission for the drive home. Thanks!
