What is a stock 4L60E operating temperature, versus after adding coolers?
Mine is pretty consistent at the 150 mark with the 40k and still through the radiator. With the stock trans cooler it was 200+
Yep heat is the trans killer

i'm with ya ducky, i run 2 in series specially on a 4l60e ;)
ditto for mineQuote:

You need it heated up to get it up to temp, and thats why you run the auxiliary cooler after the radiator cooler. I would never have gotten thru the winter up here if I just bypassed the stock cooler, because that 40k is pretty efficient and the fluid would never have heated up for most of my trips around town. And btw, I got my secondary cooler because my trans temps were up around 210-220* on average. I could only of dreamed of 160* temps before that new cooler

The important thing about the tank mounted cooler is that it brings the over 210 degree temps down to 210 very quickly when needed. If you ever got the trans fluid up around 230 with an air to air cooler it would take a very long time to cool it down. Running a big stall with gobs of TQ will cook the trans fluid in no time in stop and go traffic without quick cooling. Pull a trailer and it will aggrevate the situation even more.
yeah it seems that retaining the stock cooler and running the aux cooler inline gives you a more stable and consistent (along with being lower) temp range
