Is your auto really laggy?

Is your auto really laggy?
Mind you I haven't even put 1500 miles into yet, but man this tranny has a hard time 'learning' my driving style. It's like it can't understand how to mix and match punching it with cruising. It's like the tranny computer(I assume there is one) can only account for one type of driving. Am I wrong and what can I do to get better throttle response?

If you're not already doing it, run 93 or better octane in a full tank and see if when you clamp down on it, it doesn't kick down sooner and have more power from there.
On mine, with low octane, I have to leave the pedal on the floor for awhile longer before it will kick down & of course, I hear valves knocking.

What kind of car are you coming from? I bet that has alot to do with it. I came from an ES300. Big throttle difference IMO. I could quickly apply a good deal of pressure on the gas pedal in the ES300 and it would smoothly take off, pretty much no matter what.
Quit mashing the pedal and apply a light slowly increasing pressure. You'll get it. I can drive my I30 just as smooth as my ES300 was, but my ES300 could never be as quick or as fun to drive as my I30 is.

This could be effecting the TCU's(if these cars have them) learning process.
My issue more specifically......
1. If I want to drive all out I have no problem. Pedal to the metal and the cars responds exactly how I want(not a problem)
2. If I want to slowly accelerate and drive very casually the car responds as I expect.
If I want or NEED to mix and match the two (1) is so laggy. It's like it kicks in 2 secs after I need it to kick in and sometimes I'll just be trying to do (2), but only need a slight burst of speed. It's like the car will kind of get ready to burst then it'll burst. The problem is that's too much. I just want a quick burst to get in front of someone or to get on the highway not WOT.
Any thoughts?

It sounds exactly like when the wife drives mine & I get it back with cheap gas in it. Throw a tank of good stuff in it and if you really want to know if there's a difference, grab a bottle of octane boost (several brands available) in addition and see what happens.
...At least throw in a bottle of Techron Injector cleaner and put in 10 gallons of high octane.
The next thing I'd try (if no difference) is pulling a couple of the spark plugs to assess their health and also look at the airfilter.
(I bet the Diamante didn't also have a factory recommendation for premium fuel....)

This is normal... Sounds like the basic 'lack of performance' operation in any auto tranny... Instead of holding the gear and allowing you to accelerate, it hesitates, then down shifts which is too much... It comes with the territory of owning an auto.
#14
Im just tired of having to bring in the car to have the shift solenoids replaced. Had it done at about 20k and now an fifty (OMG, my car is middle-aged) the car is starting to shift slowly again. Oh well, I guess thats what the warrantee and Infiniti's service is for.
#15
My 98 I30 sometimes has hesitation as well but it usually only happens when I'm turning at a light or stop sign. As soon as I turn and press the accelerator it hesistates for about 2 seconds then I get a huge burst of speed. It doesn't do this at every light just occasionally but my car has 172,000 miles on it so I guess that can be expected. I've just gotten used to it...

It feels like a slug because the tranny does not down shift into the appropriate gear so when you come out of the corner you are still in the higher gear and thus the acceleration is poor... Only until you actually push the accelerator harder does it down shift.
I swear, I would be nearly completely stopped going thru a yeild turn and the tranny should have put me in at least second, but instead in only went down into third and then when it comes time to merge I felt like a snail...
Thank God I dont have to deal with this bullsh!t anymore... Car does exactly what I tell it too now.
#17
It won't "learn" it. It's not an adaptive transmission. Unfortunately for all of us with autos, it's nothing more than a good old regular 4 spd auto. However it's flawless and seamless, and the ratios aren't that bad.
Still though what if they threw the 6 speed in the I35. I sometimes wonder how the VQ35 would scream with a manual tranny. My old 97 VQ30 ran like no other with the 5 speed.

Hehehe....that would be cool. I do wonder, however, if the manual is THAT much faster around town and at regular speeds. Around town and at regular speeds the auto is pretty freakin fast. Traffic can dissapear in the mirror in a heartbeat when indicated lol. The only screnario I see a 6 spd 3.5 absolutely oblierating an auto would be at speeds of 80+.
Otherwise I don't think the 6 spd would beat the auto by all that much. Yeah it would win, but it wouldn't be a pointless race IMO.

The low gears... off the line, is where the greatest advantage a manual has! The 1st and 2nd gear ratios are vastly different. Its at speeds of 80+ a manual is not that much faster (although even at an 80+ acceleration contest the maunal would still pull away).

The reason I presumed the manual would be so much faster at high speeds is because my old car, a 97 SE 5spd, at high speeds was ridiulous. You didn't even need to take it out of 5th gear unless you ABSOLUTELY had to. It would coast past 100-110 with merely a tap of the gas.

1. Replace your tranny fluid with Mobil synthetic.
2. Buy a grounding kit and voltage stabilizer off of eBay. total cost will be around $35.
3. When you install the grounding kit, clean off all of your grounding points -- including the ones that will not receive the extra wires -- with steel wool or very fine spandpaper.
4. For about a week, pretend your automatic is a stick shift and alternate automatic shifting with MANUAL upshifting and downshifting. For example, from a dead stop, leave it in 1st until you reach 3,000RPM, then shift into D when you hit 4,000RPM. Downshift into 2nd when slowing down for a turn or a stop. Turn your O/D switch off when you are travelling 25 MPH or slower, or wish to down shift at highway speeds.
My tranny had a really bad lag -- especially when the AC was on. It was so long at times, that I almost got into an accident because I could not execute an emergency maneuver fast enough.
I swear, it made me so mad that I wanted to trash the car because of it.

BTW, my car is at the dealer right now for my slow shifting tranny...
Just called and said that my MAF was at fault. They are replacing it right now under warrantee, as well as bumping my timing up to 17 before TDC like I requested
Hopefully I'll get the car back feeling like the G35 I'm driving right now I can dream can't I? Either way, the G will never have the room of my I, and actually like how my car handles and rides BETTER than the G! My car may be a bit stiffer, but the G almost feels twitchy and uncertain at times.
Anyway, Ill let you guys know how things work out.

The shift solenoids shoud not be a maintenance item... Not sure if the A32 have the problem with their trannys.
A grounding kit strengthens your elecrical grounds making it easier for current to flow to where it's needed. The better a component receives electricity, the better it can do it's job.

Im actually in San Diego right now. Took it to Discover Infiniti here where I bought the car. That dealer is so awesome. they have always tried to do everything to help me and never charge me for anything (except a filter this time).
Infiniti of Denver sux in comparison. They dont try at all (although they do have 2005 loaner cars). I brought my car there for the same probem I brought it to Discover for, and they said nothing was wrong and just topped up the tranny fluid.
I hear today that Infin of Denver pulled a MAF code, put it in the system but didnt take the time to do **** about it! Discover replaced my MAF under warrantee, advanced my timing to 18 before TDC as I requested (actually one bump higher), and even emptied my new oil catch can . They really do know customer service here.

Yes, automatics are nice for high powered dragsters because they are very consistent and can be made to shift very quickly.
Unfortunately, in our application there is more drivetrain loss and we have one less gear to spread the power out. The 5-speeds will take autos at the track unless you're heavly moded.

I dont know about you, but I can slam second gear in my manual pretty God damned quick. Not to mention I get burn out on the 1-2 shift when I nail it. No way is an auto quicker.

Hey guys, **** off, (j/k), I'll just go pick up an SL600 convertible, rip to 60 in 3.6 seconds and the 1/4 in 11.9 with my stock automatic tranny 500 HP Benz STOCK FROM THE FACTORY. That's absolutely insane, yes the numbers are accurate.

Wrong. First of all the FORD costs 157k, more than 30k north of the SL600. Second, the Ford has the same 0-60 time and a quatermile time of only .3 seconds faster. It wouldn't eat the Benz for breakfast at all. Yeah, the Benz with a 5spd auto. What's more, and what I was originally saying, the Benz isn't even made out to be a race car, yet it will out accelerate almost everything and anything on the road. I was just pointing out that you can have all the luxury and prestige of one of the finest M-B products and yet eat up Ferraris and Porches at the drag strip- with an auto. That's pretty impressive.

At 1.5 sec. apart in the 1/4, they difference is night and day. The gt would several car lengths ahead before the driver of the sl could even plant his foot all the way into the gas. ****, he would give up at 60 cause the gt would be al the way down the road. Pretty sad for twin turbo v12... Hell a 350z with the basic bolt ons would give that thing a run for its money!!
I'll admit that I exagerated the price of the sl, but my point was that german cars are a huge rip off for what you get. The only benz that is in the league of the gt is the slr mclaren (both achieved the exact same 1/4 mile), which I am afraid does indeed cost 4 times as much...

Street start, 5-60 mph: 4.5 sec
Standing 1/4-mile: 11.9 sec @ 120 mph
Top speed (governor limited): 155 mph
They also went on to say:
"Cut to the department of elapsed time. From a standing start, the Mercedes SL600 can hurl its 4501-pound bulk to 60 mph in 3.6 seconds. Does that sound like a very brief interval? Clue: yes.
Allow us to illustrate.The Porsche 911 GT2 we tested in March 2002—456 horsepower, 457 pound-feet of torque—required 3.8 seconds to achieve mile-a-minute velocity. The Dodge Viper we tested in November '02—500 horsepower, 525 pound-feet—took 3.9 seconds. The 911 GT3 and Ferrari Challenge Stradale in our January issue each clocked in at 4.0 seconds.
Let's check the next notch on the elapsed-time yardstick. The 911 GT2 covered the quarter-mile in 12 seconds flat, the Viper in 12.1, the GT3 and Stradale in 12.3 and 12.4, respectively. The SL600 did it in 11.9. That's not quite as quick as the Ford GT, but it would have put this elegant Benz in a tie for fifth place (out of 15 cars) in the quarter-mile elapsed-time competition in our September 2002 "Supercar Challenge."
So yeah what if the GT is a few ticks faster, like I said, this is the top-dawg Benz, that will blow Ferraris and Porches away all while the driver is enjoying the luxury of one of M-B's finest products.
#39
BTW, regarding top speed, I can't directly reference the 600, but Motor Trend did a high speed test a year or so ago with a CL55 which has the weaker engine. Top speed of 187 with the governer still on. What MB did then was remove one governer or something like that, I do remember them saying in some form or another that completely ungoverned the car could attain 200. And this wasn't even the V-12.
