Does anyone experience lag in their automatics when they are in 2nd? When my car (automatic) is in 2nd gear it doesn't really get going until it hits about 1.8k RPMs. This is most noticable when I slow down to almost a complete stop and my car stays in 2nd. If it goes under 1.8k RPMs in 2nd it won't really get moving until it hits 1.8k RPM again. Its not terrible, like it won't go at all but its anoying as hell. Its almost feels like its catching another gear @ 1.8K RPMs, but I know this is not the case since my RPMs don't drop. Any clues? Thanks!

 

I experiance the lag that u explained also..nothin big though

 

It sucks, huh?

 

yeah - its the great auto tranny that nissan made, it wont down shift to 1 unless you come to a full stop

 

Is there any way to alter this and make it drop to 1st? I will do anything short of a 5 speed conversion to make this go away! Ugh!

 

manually down shift it to 1..........its not good for your transmission though in the long run.

 

The problem is that our little 3 liter engines lack power/torgue at low RPM and when the tranny does not shift down to low and you give it a little gas, at low RPM, it is lugging the engine. Like trying to start out in 2nd in a 5 speed. Just push down harder on that long thin peddle and it will down shift to 1st and vrooooooooooooom, away you go...

 

vb mod is best, you can do the resistor trick, but it's awful for the life of the tranny. Also, try this, before hitting the gas, let go of the pedal completely and then floor it. I dunno about 2nd gear, but when you're cruisin and about to pass at 40-50 it does the trick.

 

True it will go, but then its just way to fast of a launch and people think I'm nuts if I just slow down around 45mph. If I do that its pedal to the floor trying to reach 80+ mph. Thanks any ways.

 

You should not have to floor it to get the downshift to first. Just slowly press the pedal down and it should shift down quickly without jerking. If it does not then you have a tranny problem. First thing I would do would be to flush and refill tranny with synthetic fluid. If this does not work, you are in need of some VB work.

 

rotfl !! @ ur sig pic !!

 

lets face it.. while the max is great overall, its tranny is a piece of crap compared with the others. In fact, dont you ever wonder why with the same or more hp, nissans are slower overall? example: Q45 with 345hp and still cant do a sub-6 second 0-60...or the 02 max (still a terrific car) with 255 hp and still cant outdo the type-s with a clear margin even though its lighter. Nissan should spend a little more time on gearing and trannies. then our maxs will be killer!

 

How would the TCU controller sold by Cattman peformance apply to this problem? I'm sure I could have done a search, but since we are already on the topic.....

 

so far i've only heard of one person using it and from what i hear it didn't do much, if anything. this was 5-6 months ago, so search to find it.

 

let's start with the fact that the Q45 is:

A)3800lbs
B)A luxury car, so smooth (slow) shifts are preferable

As for the max vs Acura, from what I've heard Acura's trannies aren't that great either. The max has about 300lbs less curb weight and an extra 14 ft-lbs, but 5 HP less. This is a fairly small difference and, on the street, it could go either way.

 

The reason the Q45 doesn't produce sub six second 0-60 as advertised is because:

1. The final drive ratio is too low (numericaly) to produce a good launch. For 2003 the Q45 gets a new 3.33:1 rear diff.

2. The ECU limits torque braking to 1500 RPM which is not very effective.

The Q45 has an excellent, silky transmision which is also in or will be in the G35, G35 Coupe, 350Z, and the M45. Go drive one of those cars and you'll probably agree.

The Max's auto isn't great... the new Max's and Altima's need a redisigned 5 Spd Auto IMHO...

 

GS430 0-60 5.8 3715 lbs
Q45 0-60 6.5 3800

 

Edmunds.com:

2002 Lexus GS 430 Luxury Sedan Acceleration (0-60 mph): 6.3 sec.
2002 Infiniti Q45 Luxury Sedan Acceleration (0-60 mph): 6.7 sec.

The 430 is almost a 100 lbs lighter and has it's torque lower down than the Q45. No doubt the difference could be made up by incorporating a more aggressive transmission/shift points into the Q45, but that isn't the car's mission and its target audience wouldn't really care if they can beat a GS 430 to 60 MPH. They care more about having a quiet, spacious, gadget-laden, smooth, reliable and comfortable luxury car with a bit of muscle to bring them from point A to point B.

 

0-60 5.8 GS 430
Ill trust motor trend over Edmunds.com
Oh and its an 86 lb difference.3801-3715 = 86lbs
Not exactly a Drastically handicapping difference. Keep in mind the Q has 40 more horses and 8 more ft/lb torque over the GS.
And the gs isnt necessarily considered less reliable, smooth, quiet than the Q. Actually, id venture to say the Q is still quite the underdog to lexus when transmission smoothness, and overall reliablility is the factor. We have yet to see the Q45 prove its own (although im sure it will be quite reliable nonetheless)
But ill give you the "luxury" excuse. fair call

 

Well now there is a downside to driving the automagics. All you have to do is manually upshift the car. Once your at a stop just row the shifter at the speeds you want it to shift. Otherwise your suck with the 10mph+ 2nd gear unless your throttle is more than 75%. It is in the FSM.

 

a 6spd maxima will rape a tls and a cls stick thru the butt

 

Auto for auto, the reason why the TLS and CLS are so close to us despite being down on torque and up on weight is that they have a 5sp auto whereas Maxes only have 4 gears to work with... Also, their FWHP is higher than us...

 

Their HP is 260 vs. our 255. Where is the lost hp to the wheel for the max?? Maybe this is the key to nissan's inability to match performance (0-60, etc) with HP numbers when compared to bmw, acura, lexus. Dont get me wrong though, for the $$, the max is a great buy. thats why im here right!?
Oh and 95emerald, i wouldnt call it "rape" the cl-s 6-speed clocks 0-60 at 6.1, quarter mile 14.7 sec stock. This is with a 3450lb curb weight! The 5-speed cl-s AUTO does 6.5/15.1. The 02 max does 0-60 in 6.4/ (MANUAL 6-SPEED) with a 3248lb curb weight. With over 200lb weight advantage and 14 lbft more torque compared with the cl-s, the max is still slower (6speed to 6speed)
With my $$, id still prefer max. but i still give credit where its due, and the cl-s deserves some too.

 

car and driver a very base q to 6.0 or 6.1 can't remember

 

Now it gets to the point where it really depends on the driver..Ive seen bone stock 2k2 6spd max's running 14.4-14.8's..It really depends on the driver
