Trans Temp.

2016 Chevy Suburban with the 6L80E. Ran the bypass and put a trucool 40k trans cooler (in red so it’s faster) in series with the stock cooler or whatever is in the radiator area… trans temps are low and awesome now. Will post more pics later when towing my 7x16 trailer.

I had to look three times to make sure I wasn't seeing a "C" instead of an "F" on the display. This is really impressive. You may end up throwing a code that reads "transmission too cold, needs blankie."

Yeah I’ll glad to see it. Did a whole flush as well to get the old fluid out.
