The shop foreman at the Ford dealership my son works at is going to fix my P0451 and P1450 CEL codes on my F-150.
While he has it he's going to drop the trans pan and change the filter and 4 qts. of Mercon V (Motorcraft Mercon V & MC filter). He is also draining the differential and adding Valvoline synthetic 75W140 gear lube ($10.19 per qt. from NAPA). He will be using a Fel-Pro gasket ($9.16 from NAPA) to seal the cover.
