To those with the auto -any throttle lag or hesitation at low speed?
To the members that have the auto, is there any throttle lag or hesitation when pulling from a slow corner or rolling stop? I have read all of the reviews and have seen no mention of this but I would like real world input. I am aware of the ''idle issue'' and am not asking about that. Many of today's autos (including Subaru) are programmed with a slight hesitation or lag. It can feel like the engine cant decide what gear to be in for a split second or it can feel like the ecu simply ignores peddle input, sometimes for up to a full second in the bad cases (04 Toyota Solara). Is anyone experiencing this annoyance?

I've noticed no lag at all, either in full auto or manual mode. I contribute this to "good programming" as much as anything. Based on what I see on the display, the auto's brain always knows, based on the mode you are in, if it is acceptable to switch up or down a gear, so if the request comes in, it just does it.
You can see this on the display in manual mode where it constantly displays next to the gear number an up, a down or both arrows letting you know what you can do. |

I have been very impresses with the automatic transmission. Light years ahead of my 01 Prelude. Very smooth at any RPM, but youll be in manual mode more often than not

First you should know that I ordered a manual and ended up buying an automatic after test driving them both. I did not feel like I was loosing any performance by going with the auto, plus I'm not 20 years old anymore (ie no street/drag racing) and this is my daily driver (comfort, mpg, etc.)
But to answer your question, mine has zero lag. It knows what gear to be in based on speed and throttle position. Manual mode feels just as quick as driving a manual trans. They did a great job with it IMO. |

I've noticed a bit of a lag in downshifting when it's in sport mode, usually at highway speeds. I've had the same issue in my Lexus IS250 which has essentially the same transmission. I think the computer might get a bit confused on whether to downshift 1 or 2 gears. Doesn't happen all the time.

I have not hit any lag on the Auto. It does however get confused going on a steep and windy hill on low speed. It will keep the revs at 1500 rpm and will hesitate to downshift if I keep it a certain speed (which happens to be around 15-20mph due to up hill traffic) However I do just tap paddle shifters to kick it down or push more on the accelerator.
Other than that, the AT is a champ! |

I think when you get an automatic with 6 speeds there is some computer confusion. I once floored my Lexus IS250 to pass and rather than downshift from 6th to 5th it went in to 3rd screaming at 6000 rpm. 6th is pretty much an overdrive and probably what I should have done is press the accelerator less exuberantly going for 5th or 4th gear. Still getting used to both cars automatics.

I noticed a lag occasionally when I took it out for my test drive. Hasn't been a problem since, or maybe I'm not as attentive as I was when I was checking it out. Or, maybe the ECU calibrates after a certain amount of miles?

2. Auto gets better MPG due to the longer gearing in 5th and 6th OP: Like others have said, there is no throttle lag. I haven't had a delay in downshifts either, but have only used it during spirited drives and not cruising on the highway so IDK if that is a factor. |

Well, yes, in certain aggressive attacks the nannies will limit fuel. Avoid excessive throttle and turn inputs combinations. Select Sport/VSC off mode while choosing gear selections to maintain the 5-7k power range to get the full capabilities available in the FR-S.
