I read that transmissions optimal temp is 170⁰ ish. That temp keeps moisture from building up I'm the fluid. I just got my truck a few months ago so no blazing temps. The temps were around 175 consistently now I put a bypass in it and it barely sees 120, have not towed anything nor seen hot weather in any case. I plan to keep the fluid serviced, should I be worried of over cooling my tranny, in Delaware we can get into some low temps but that is rare. I saved the oem thermo valve should I reinstall to keep my tranny at around 170?
