See the link to the new TSB below. The new lower deflector is stuck on the CAC fins/surface with adhesive tape.
Also, see the important note in the TSB:
Is vehicle equipped with latest level charge air cooler, engineering part number BL34-9L440-AE? (Figure 2)
CARE NEEDS TO BE TAKEN NOT TO INSTALL THE REVISED BOTTOM AIR DEFLECTOR ONTO CHARGE AIR COOLER ENGINEERING PART BL34-9L440-AE AS IT WILL RESULT IN HIGHER MANIFOLD AIR CHARGE TEMPERATURES AND SIGNIFICANT LOSS OF ENGINE PERFORMANCE.
I also noticed the reprogram step says to use 79.02A or higher, which is the same as the previous TSBs on this issue so no new programming.
