Re: '50 Ultramatic Trans Cooler Lines

Thanks, guys! So, my initial thinking was that I was going to take the OE cooler out of the circuit and just run the external in order to eliminate the risk of the trans and rad fluid mixing at any point in the future. The directions on the cooler I bought suggested running the internal and external cooler in circuit because it "provides maximum cooling efficiency." The directions suggest that running the external cooler alone should be done only when replacing the OE cooler is cost prohibitive.

I would say that I don't get the sense that my transmission is overheating, more just looking at options for "cheap insurance" for the transmission and cooling system. I hadn't considered the two together might be TOO MUCH cooling. Folks who have suggested the external cooler approach have just provided the perspective that it's a better option both for eliminating a potential issue with mixing fluids down the road and cooling the transmission. That said, I didn't really do a deep dive into whether the transmissions are prone to overheating (or just running hotter than they should). Not an engineer here - college band director lol, and just trying to figure out as I go.
