2016 Sierra trans temps...........
Saw a high of 194* on the highway and now usually 190* and then coasting down on the off ramp doesn't seem to drop for a few miles/ I understand that these new trucks have a thermostat controlled trans line that opens when deemed necessary. can this be tuned lower? Oh yeah- truck is a 2016 GMC Sierra 5.3 6spd. Just looked around upfront as I didn't get to putting on the Tru Cool on last truck but I don't see an aux cooler for the trans. Any info greatly appreciated...………….. TIA

I can't remember who but he is 14+ that gave a play by play on what to do to lower trans temps. No cooler needed. I have a 40k as well but it wouldn't fit with the he of the Whip. He tells how to easily and simply mod the 6spd to bring it down to 140-160 as I recall. Btw my temps are the same. Just search it.

That brings a lot of peace of mind, FF. 196* is the highest I've seen- was just getting kinda leery that I was mostly over 190* and now knowing it's a design parameter in that they want the fluid that temperature for functioning, I'm gonna sleep better now...………..

I've seen 204-205 at least after back to back passes. Drove it back in a lower gear with the heat on lol.
