^ no, the ZF in 335 is better (faster reaction time) than 330

After having the car back from the dealer, the throttle responses better now but not as well as the 320i that I owned before.

The 320i that I had before went up to 6500 every gear (D mode). Just gently depressed on the gas pedal down to the floor, no need to kick down.

Anyway, I will try according to E90Fleet.

Thanks

The 320i will stay in gear longer, because its a much weaker engine and needs to rev high to keep you moving.

The 325i will change earlier with small amounts of throttle to keep down fuel consumption.

Just keep it in DS mode if you want it to hold gears longer

Is the ZF transmission the same between the 330 & the 335?
335i has a newer uprated gearbox from ZF

AH HA!!!!!!!!!!!!! my suspicions are confirmed....

When I test drove the 335 with paddle shifters(as much as I was warned not to by others on this post) I thought the shifts were firmer and faster.

I thought it might be because my car has more miles or I needed to "reset" my xmission? silly me

turns out...my suspicions are correct...the 335 step is indeed different.

Oh well

You could also have read the press release or brochures for the 335i, its listed as a feature

Hello... I drive a 320i E90 2009.. with 14000 km spent now.. I have a terrible 2-1 shift.. I can feel it everytime as if something hits inside the gearbox.. Would this reset do something with that knowing that I got this car used only 3 weeks ago (1000 km ago)?

"1. Turn cars electronics on-push start button once or twice without turning the actual engine on.

2.Hold the gas pedal to the floor for 25 seconds
3. Most times you will hear the gearbox resetting itself and hear some "noise" coming from your car but not always noticable so dont worry if you dont
4 Now start your car and enjoy the gearbox reset to its factor settings and open for all new learning. The shifts are silky smooth again and shift points shift faster-basically it totally makes your tranny perform better. "
