Just got my car on the road after doing a bunch of stuff and putting a new transmission in. I am running through the stock transmission cooler into one of the larger B&M stacked plate type coolers, and even after driving the car for 30 minutes the transmission temperature only gets up to about 110-120* (It was only in the 50's outside though) Is that too low? I know a lot of people say 160 is good, and every 20* drop will practically double the life of the transmission, but I know there has to be a limit or point when it's running too cool. FWIW I'm running dexron 6 fluid.
