+1 to everyone who said tranny adapative learn strategy. a 4hr drive alone probably did not reset it completely. i dont feel like looking it up exactly but turn your car on and let it get to normal operating temp. let it idle for 1 min in P once fully warmed. turn on a/c for 1 min. turn on defrost for one min. use shifter to shift between every possible selection x5 or 10(i think its 5 but i would do 10 for sh*ts and giggles). also start in d4, accelerate normally to 45 mph, cruise for at least 15 seconds, then throw it to d5 and accelerate to 55mph and cruise for at least 15 seconds repeat X5 chances R you probably did everything else in your 4 hr cruise. the one thing i would also recommend (never saw this in a book) is if you normally do not let your car warm up all the way, go through all the options with the shifter x5 or 10 when its cold too. sometimes i get a delay when its cold bc i normally let it get off C before i do anything. lastly you need to have idle in d5 for 5 mins (i dont remember exact minutes, it might be 3 mins).
after doign all that i think the only thing that you might not have done (unless you drive pretty wild) would be something with the throttle. you will notice it if you do like a rolling stop or a sharp turn and then go immediately to WOT, you will get a huge delay the first 5 times. i dont remember what the procedure to set it is off the top of my head and dont feel like combing through a thousand pg book. you wont notice that one anyways unless you drive like a crazy person on the reg
