Need help with new E430
had a quick question..here is the background. just bought an E430 4matic still under extended warranty for 11 months or so. has 74k on it. had some vibration issues and replaced all 4 tires. continental extreme contact. i think it feels good so far (200 miles). purchased an installed at a honda dealership because of their unbeatable price. i am yet to get them aligned at MB dealership (coz honda said they cudnt do it on this vehicle).
so here is a new phenomenon that started RIGHT after getting new tires (atleast i dint notice it before that) - car shifts gears weird before 20mph. so if i am at stop sign and accelerate from there, it has some lag and then thursts..then it goes ok for 5-6 mph and then it does the same thing with that weird gear shift..then it just runs like a dream..not sure what happens here
things that were done recently
both front shocks replaced and one f.axle boot replace (all at dealership)
i cant explain exactly how it runs but it feels a little weird..can anybody telediagnose the problem?
thanks a lot,

previous owner says he had transmission fluid changed within last 10k miles.
also, it doesnt shake at any speed at all..it just runs smooth after 20 mph.
please help.
Also, since I commute to Boston everyday. Once and a while in traffic, the car tends to shift a little wacky, but that has not happened in a couple of months (knock on wood).
Hope this helps.

I would suggest you try S mode that way the car will start in first gear and have better acceleration with out down shifting.
One other thing to have checked is the transmission fluid level, it requires a special tool and must be exactly correct or you will have shift problems.
so will it help to take to a dealership or suck it up and keep driving? it improved a little bit after i did ECU reset..but still has lag in lower gears..
thanks again,
