I've never driven a 5.4 Raptor though. I misspoke in my statement. I meant the 5.4L as in the old truck not the 5.4 Raptor. Didn't the 5.4 Raptor have different tuning/transmission?
it's the same transmission but the engine and trans are controlled by 2 separate control modules on the 5.4's, where the 6.2 has 1 control module for both.
supposedly some of the shifting complaints 5.4 owners had was due to the 2 computers communicating more slowly than 1 main control module.
there's a ton of data that has to be passed between the engine and trans control modules and just that extra split second for the two computers to play nice is what causes some of the hard shifts, hesitation and gear hunting on the 5.4.
with that being said the 6.2 also experiences the same problems, just not quite as bad. the point is that there's a ton of information being put out by the engine and trans and sometimes instant response and performance is put on the back burner by the truck basically wanting to always stay in a higher more fuel efficient gear.
