Hey all,

Wondering if anyone has any insight on running low temps on an 05 LLY. I swapped the rad/trans cooler to a Mishimoto setup when the truck was first bought, Rad has since been changed back to OEM, but trans cooler is still installed, my question is about trans temps. I have never seen the trans go above 88 degrees, is this a problem? To my knowledge there typically closer to that 150 degree mark. These temps are taken after a 6 hr drive, mostly highway, but even lots of start/stop don't seem to change anything, I've never seen it go higher than this. I have IR gunned the pan, and verified that the temp reading is correct as well. Will this cause me issues?
