Q1: no, that is perfectly fine.

Q2: the ecu wants to avoid excessive lash and redlining on downshift, so it restricts you from downshifting until certain speeds, and tbh, there is very little need for 1st gear unless you are at a stop or nearly stopped. in other words, why would you want to downshift to a redlined 1st gear? where are you gonna go from there? right back up to 2nd?
There is a table* in the owners manual that tells you the recommended shift points and allowable speeds for downshifting.

Q3: it's fine to let the car downshift on it's own. it's keeping the engine from lugging or stalling because the revs are too low.

DUHN THE MANUAL haha

last question:

When i first started using M mode, i forgot i was in M mode and i redlined. The needle went all the way to the 8 and the car jumped. Immediately i let off the gas and put into D. Now, stupid me, that was not the first time. I did it prob 2 more times. and this was when the car was still a baby. What did i do to the engine/tranny then? What happens?

nothing. maybe it cut the fuel off?

somebody's sister borrowed his car and accidentally bumped it to manual mode and drove 30 miles to the airport in 2nd gear.
Mom: Why don't you go faster?
Sister: It's as fast as it will go!
:lol:

Your cars fine I would think it would take more than a couple redlines to hurt the car.

I've bounced mine off the rev limiter a couple of times. What's happening is that the ECU is cutting fuel to keep you safe, and since you are on the gas hard, it'll feel like you just slammed into a curb - the nose drops and you get jerked against your seat harness. Shouldn't hurt anything but I personally wouldn't make a habit of it.

My AT Sport Shift has been fickle lately. I have no problem upshifting; but when it comes to downshifting, it sometimes does not want to go at all. Is there a sensor or something that needs to be replaced?

The car won't let you downshift if it's going to bring the rpm over redline.

Not talking about redlining; basically for instance trying to shift from 4th to 3rd going around and under 40 or down from 3rd to second at low speeds; seems now it wont let me downshift at all. Back to driving on full auto atm.

I don't even use regular D anymore. Always straight to M. I want a manual, see, and this is as close as I've got at the moment :lol:

+1.

Another solution to solve this is bringing it in to your local mazda dealership and asking them for a ECU reflash. This should be free as the warranty for this should be 7 yr / 128,000km. This has been discussed on my main mz3 forum (bcmazda3.com) and it has solved a lot of members' problems with their A/T 1-2 shifting.

Hope this helps

I know for sure it covers the 04 and 05 model years with the 4 speed auto. Not sure about the 5 speed auto in the 06.

Recently bought a 2010 M3 GT 5 door with AT Sport Shift Tranny and wanted to share my thoughts. Let me preface this by saying that I drove exclusively manual transmissions for the past 16 years and am very skilled with a stick. When I went to the dealer though, they didn't have manuals in stock and I would have had to order one, wait 120 days and possibly miss out on the June 0% apr 60 month financing promotion (which I qualified for, a major incentive btw). I skeptically test drove the M3 automatic and was curious about the tiptronic sport shift capability. Coming from driving a late 90s toyota Tacoma, the M3 I test drove just blew doors on any car I'd ever owned. Serious torque, power, 0-60 in about 7.5 seconds, handling, overall performance and I thought the Sport shift feature a somewhat 'happy medium', since being an L.A. resident and spending considerable time in stop and go driving conditions, the auto might be a welcome change at times with the option to drive it hard and wind it up in manual mode.

I was initially having issues with the sport shift manual mode, specifically with the the slight 'lag' in the shifts between 1-2 and 2-3 which was driving me crazy. After doing some research and spending considerable time getting the manual mode down I realized that it is a skill that is (a) not to be underestimated and (b) takes a while to master. Unlike other automatic tranny cars I have driven in the past (which I hated), the manual feature on the M3 (which I imagine operates superior to the 2.0 liter version) definitely requires a high level of driver/car relationship and involvement that is similar in some levels to that of a straight manual. Only after getting a good idea of where this car's power and ideal torque ranges lie in the powerband did I discover the best points to shift in manual mode. I have found that when accelerating onto a freeway for instance and winding it up that 4000 rpm is an ideal place to shift from 1-2, and 3500 or so for 2-3, both of which provide very quick shifts with virtually no lag, faster, I have found than any shift I have ever done with a manual. As "fun"? Maybe not, but unless you are a diehard manual purist (all 500 of them that are left), you are really splitting hairs. Once in 3rd gear and up around 50-60 mph, shifts are extremely smooth and the car just purrs along and really gets on it, providing me with more power, torque and 'performance' than I really need - plenty to get me into trouble. Another great feature of M mode is when passing, especially going up the Grapevine back to L.A. in 5th gear and wanting to pass some horrible Minivan, if you get down to around 2000 rpm and bump it down to 4th gear from 5th, there is an instant surge of power with enough headroom to comfortably do 85 up a steep incline, passing all 'baby on board' minivans and urban assault SUVs. When driving around town in stop and go traffic, I slip it into D and chill out, allowing time for me to shuffle through my iPod and rock the Bose system.

So now that I have driven the car a while, I have to say that I like the tiptronic 'manumatic' feature and would never drive a stock automatic. The hardcore stick enthusiasts out there like to talk about manuals being '1 second faster than the automatics "off the line" which to me is just hilarious. "Off the line"? Are you serious buying a 22K economy car so you can race it? These are the guys that try and pin it, doing 0-80 in between each stoplight. Great. If you want to drive like that, my advice to you is to move out to the desert or montana somewhere because in L.A. it is pointless. And anyway, if the tiptronic transmissions didn't 'perform', they wouldn't be used by professional race car drivers and installed in high-end sports cars.

The times I do get to open this car up on the freeway though is when I am exhilarated by the power and performance of this vehicle. Do I still miss driving a stick? Sometimes, but in a way, the semi-auto, tiptronic, whateveryouwanttocallit transmission thing is in and of itself, a whole other thing to master and enjoy and I would think that those who have experience driving stick will be able to use the manual mode more effectively than those who have never driven stick. I must say though that it perplexes me that there are so many people out there who simply can NOT drive stick. Considering I learned on stick when I was 14 (I'm 33), I can't imagine not knowing how but from what I understand, the sticks are a dying breed and account for less than 10% of cars sold in the US. I used to think that was a shame, and maybe it is, but with these automatic trannys getting better and better and in some cases, outperforming the sticks, I guess you've got to move along with progress. I figure I'll keep this M3 for a good 7 or 8 years or so and it remains to be seen whether or not I'll go back to manual or not (if they even still make them).

Recently I noticed while I let the car downshift on its own from 5th to 4th, it skips to 3rd (the "4" shows in the dash for like a millisecond). I know that the 3rd-1st downshift is normal, bit is 5th to 4th? I may be having ATX problems but wanted to know if anyone else has experienced this.

I've been experiencing the exact same thing on my 04, mostly when trying to upshift. I've not been able to find much information on the symptom. What I have found has been limited to what's in the Mazda service manual which is not much. The manual references troubled wire connection leading to the ECM (engine control module). However when I took a look at the components under the hood nothing seemed out of the ordinary.

Specifically what's happening in my case is that when in M mode, I pull to up-shift and frequently nothing will happen. Its at times taken several as many as 6 pulls of the selector lever and then the transmission will advance the gear. Frustrating to say the least as the M mode shifting has alway been my favorite feature of my car. The issues developed over the last few months, at first it would only fail to shift once or twice a day in my daily commute and be completely fine after that. But it's gotten steadily worse.

Considering that the transmission system works perfectly fine in normal D mode I started thinking that the issue is in the actual mechanism that tells the cars computer to advance the gear in M. So I took out the center console panels and was able to identify the components on the transmission selector unit that controls the manual shifting. What's in there are two small micro switches the shifter lever makes contact with. After near 40k miles my theory is that these switches have begun to wear out. I don't have a solution yet and my next step is to get the car into the dealership. If anyone's got any more information or ideas on this it would be greatly appreciated.
