MN8 : 4-speed HD Automatic Transmission- 4L85E Running Temps

Nice looking install. Hopefully that new cooler will help you out more when towing that hauler.

Drove from home to Legoland in San Diego today. Around 100+ miles round trip. This cooler is incredible! I was averaging about 120-130 on the freeway and 140-150 on the streets. That's a 50-60 degree cooler temps. Awesome!

Yeah the extra coolers are awesome. My stock cooler on my 2006 denali was pretty small. Before I swapped it for a Tru cool unit I was regularly seeing 180-190 Trans temps under no loads. Now after upgrading I rarely see Temps above 150 unless I sit in stop and go traffic which is almost never. Best 300ish bucks ive spent on a mod so far. Got a keep my rebuilt Trans protected. Good to see another socal member here by the way! I rarely sit in traffic because I live up in big bear in the San Bernardino mountains. Lol.
