So I installed a total of 4in in lift so far with 2in ADO bilstein add a leaf with additions 2in body lift. Then installed 295/75/r16 with a bit of trimming. I travel for work, and today the lady drove my truck (as she always does when I leave) and called me saying that she thinks the transmission is slipping. Described that she thinks it’s losing power and shifting at higher rpm. Recently I had a code throw for Cat bank 1 but cleared it to be sure it wasn’t a fluke and it’s yet to come back for 3 weeks. I expected a loss of power with the 33s but I’m wondering if my cat actually is clogged or if I’m having a transmission problem. 108k miles now.
