When I am in DS mode shifting myself.. Say I am going 10MPH and the car is in 2nd gear and I want to downshift to 1st, the displayed number will go away then flash back to 2 and wont downshift to 1st, again ill hit it and it wont shift to first. If I hold it then it will shift to first.. I just dont get why the car is so hesitant to be put in 1st gear. All of the other gears I can downshift whenever say from 3rd to 2nd putting the RPM's way up in the 5k range.. Its a real shame I cant do this going from 2nd to 1st.


Sorry for my rant.. Will fellow 328i and 325i owners go test this out maybe its a transmission issue with my car?

Bcs at that speed, the algorithm says it should be in 2d.

At a standing stop it has no such qualms.

I would think if you're trying to downshift a gear that will put the RPM's past redline, it won't shift for you.

Anyways, my question to you is why are you trying to shift from 2nd to 1st? Is it for more power from a rolling start? Most manual drivers won't do this at all. Once you're out of 1st gear you don't go back unless you're stopped or going really slow.

335 auto trans downshifts into 1st in manual mode with no problems at that speed.

He's probably doing it to try and keep the car in the power band. Why drive around in second at low RPM? I drop the car into first at speed all the time. This is one of the things that bothers me when I get a steptronic loaner, so I can understand why the OP does not like it.

It's only 10mph...there's no concerns for overreving.

[ska///235i]

there's no point to downshift to 1st gear.
1st gear is for pick-up only, when I 1st learn to drive stick...........one of the rules was never downshift to 1st gear unless you're at a stop

I think you should take a drivers ed class if you ask to shift 2nd to 1st

[runnerx]

That is why you need 6spd manual...

No need to insult the guy. You don't down-shift into first gear - fine. Some of us do. I think his question is totally legit.

Yea i can understand your point. To each their own. The only time i do go back to 1st is if i'm in traffic or stopped.

Anyways, this is more about Steptronic so i'll leave it up to the step guys to answer this one.

not insulting him at all......I never heard of downshifting to 1st gear when ur rowing...it doesnt make any sence

sorry

so if you're in 1st gear and you need to REV the engine....you gonna shift to reverse???

You did insult him. You told him he needed driver's ed which implies he's a bad driver.

Also, it DOES make sense if you like to keep the car in the powerband. I downshift to first all the time. Or engine brake. Or just want to keep from bogging the motor too much. Or want to accelerate fast from a slow roll. Geez, there are countless times I do this. Just because someone once told you its bad, does not mean everyone else does not know how to drive.

[ska///235i]

BMW do that in the Sports mode for a reason
you can only downshift back to 1st when the car is at a stop (not sure about 335)

I guess the rule was an old fairy tale


If I insulted the OP....no offense, I told him to take drivers ed because if he doesnt know how to shift in an automatic....nvm ........ anyways, I see so much Young BMW drivers getting into accidents. These cars now'a'days are so powerful. Without experience, serious accidents can occur...I hate those accident threads

Peace
:rocks:

[younghov85]

Even with a 6sp manual, u rarely wanna be in1st gear. I only use it if I am at a complete stop or there is no acceleration or momentum on the car. If i am in traffic in the city I just keep it in neutral and then when I can accelerate I always throw it in 2nd, its so much smoother and better on the clutch than throwing it in first.

[Ryan 330i]

i noticed this when i had a 325 loaner. however my 06 330 nor my 335 do it.

No it will not put it in the redline, if I hold it in the downshift area it will eventually listen, so right now I am in the habit of when I want to shift from 2nd to 1st I hold it until it does and it usually brings me to 3k-4k RPM downshift.

Reason why is I am slowing to an almost stop but am not going to stop aka rolling start or taking a very tight turn that requires me to go down to 10 mph and I want to jet out of it without the engine bogging of being in 2nd.

Manual cars are geared differently than an Auto car. And yes I need a manual, but even then I would put it in 1st for that extra power, I used to downshift to 1st gear on my old SMG E46 heck the most fun was shifting from 1st to 2nd at 8k RPM hearing the tires chirp, then slowing down downshifting to 1st then back up to 8k.

Learn to spell.. Then I might take you seriously.. This car has 100hp less than my old car and I am not one of the retarded members here that drives with DSC off. This is my 2nd BMW and 4th car total since I have started to drive even my old mercedes could do this without any trouble.. It just seems the BMW is very hesitant and choppy when going from 2nd to 1st.

Thank you lol...

I guess he doesnt know about throttle blipping, if your in 2nd you blip the throttle and put it in 1st and you get basically no wear and tear on the clutch, and its also very smooth that way.

I wish I got a manual but then again I had to get a car and only had 1 day to pick out a car and they basically had nothing and 0 manuals in stock.

[siriusinvestor]

The downshift range I believe is 2,500 RPM. If you try to downshift at say 2,800 or 3,000 rpm, it will not downshift in steptronic.

Makes sense! I personally don't know why it won't let you then, if your SMG let you before. Maybe it's because it's a step and not SMG?

Anyways, good luck and let us know if you find out why, maybe the dealer can help?

Okay, now that we've established that (1) downshifting from 2-1 will not overrev the engine at 10 mph, (2) it is possible to downshift back into first while moving in a manual transmission, and (3) the OP is clearly not among the contributers to this thread who needs drivers ed...

I'm curious. If you keep the step in drive/automatic mode, and floor it while going 10 mph, is it willing to downshift into first? In other words, is the problem only in manual mode?

Interesting, the owners manual makes no mention of this. It simply says:

Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system. The
gear selected is briefly displayed in the instrument
cluster, followed by the gear actually in
use.

Also, the 2500-rpm theory is clearly not the case in the OP's example. At 10 mph in second, the engine shouldn't be much above 1000 rpm (it certainly isn't in the 6MT) and the gain in revs for a 2-1 shift should be less than 1000 rpm. I can think of no reason a properly functioning transmission should reject a 2-1 shift in this situation.

If E90Fleet is around, I'd try to ask him what's up, but my vote is that something is not right with your tranny.

[montreal_bimmer]

should downshift in that range....
