I just had my 15 5.0 done at 34k . I too can feel a difference. Not that the shifting was harsh prior to service. The downshifts are where I notice the difference.
Exactly my experience as well. We change our engine oil so regularly/often it’s hard to notice a difference, but the longer change interval of the tranny fluid makes it noticeable when changed.
