disagree with last part, have used 4a in f150 in the past for thousands of miles and zero i’ll effect. Manual indicates it is safe in all on/off road conditions4a is good if your hard on the skinny pedal in rain. With our torque management it’s not needed through the first 2 gears but can save your ass in a kick down situation grabbing 2nd or 3rd especially if the wheel is not straight.
Normal driving, I see no use for it. Just excess wear and tear. Be lucky to make 40k miles running 4a on dry pavement daily.
