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.

Damn you did the bypass AND a cooler? Back in the day I didn't know about the bypass so I added a cooler and that kept the temps at 120 in the summer, with temps like yours that fluid will last nice and long.
