So my fan clutch is not grabbing second and third gear.. first noticed a/c wasn’t working when it got up over 90 replaced condenser and the fan clutch didn’t fix it. Then I pulled my toy hauler and on a long grade 90+ out I got up to 240 deg. No fan kicking in. Any ideas I know Lml is controlled via ecm. Truck is deleted and twinned, built trans and a bunch of other mods. All in truck performance tuned it anyone had this problem
