I put the thermo meter on it cooler is working but my cat converter is working even harder at super heating the tranny lines up to what i got was over 250 deg both in and out so it must be filled with river silt that is now a clay pot inside the cat. So i'm gonna pull it out then make a straight pipe for it and I bet the tranny will run under 160 degs. I hate cats. BTW the tranny lines run inbetween the exhaste Y before the cat for those who don't know thats why its getting super heated from mister cloged cat bet my truck will run cooler too now.
