If this has been written before i'm sorry but i'm having a problem with my TL. I have a 6M 04 and the RPM's are sticking when I put the clutch in or if I put the car in neutral. The RPM'sstick at every thousand for about 5 sec. Some days less. My car has less then 3k miles on it and it just started doing it. I took the car to Acura and they said it was the gauge cluster and that they would replace it. Well, I had a feeling it was not that. So 3 days later they told me that all the 04 tls do this. They told me that was normal. Well, if this is normal, why did the car never do this before. Please can someone tell me what is going on.

 

it is pretty normal..... bmw, hondas, almost every car maker has this problem..... no biggie

 

I have never heard of this happening. Is this malady peculiar to 6MT, or can any make; model, or transmission type be affected by the lingering tachometer syndrome?

Tachometers are supposed to smoothly operate around the dial. I can't believe that some cars have tachometers that just take a rest every once in a while.

 

I'm confused. Is it the actual rpms (engine speed) that are holding at certain levels, or is it the tachometer needle that stays motionless regardless of the engine speed?

 

I believe both the RPMs and the engine but i'm not really sure. I would think that if you are drivng and you take the car up to, lets just say 6 thousand rpms, when you push on the clutch the rpms should just drop nice and smooth to 1k. But for my car it will stop at 5k for a few secs and then stop at 4k for a few secs and so on.

 

If it is, in fact, you engine that's hanging and not just the tach readout, then NO this is not normal for this car at all. You could have an air bypass valve or MAP sensor problem. Or perhaps an OX sensor is reading what it believes to be a fuel puddling (real or otherwise) problem in your intake manifold.

Have this looked into.

 

I have had cars that are stick (and acura gsr) and never had that problem. If anyone has a 6speed please let me know if this is happening. I could understand if it did it when I first bought the car but not 3 months later. Its funny even the tech guy did not know and thought it was the gauge cluster. They replaced it and UMMMMMMMMMM did not solve the promblem.

 

Well Acura told me that all the 04 tls do this. They said they drove a few that were on the lot and they do the samething. So I think i'm going to have to take a ride in another tl to see for myself

 

1) My 6MT sticks at least once on the way down, because it is rev matching for a gear change. IE: Your going from 3rd to fourth, it stops the revs at a certain point that would match exactly where the needle needs to be to shift into 4th gear. I never checked to see if it stops again on the way down.

2) Go back to the dealer (or another dealer who doesnt know you) and simply ask to test drive a 6MT TL. If it happens to "ALL 04 TLs" as they claim, then it should happen on that car.

3) Find another 6MT Driver in your area of FL and see if you can hook up for a sec and swap cars. If theirs doesnt and yours does, you both should notice the difference.

PS: Next time you drive your car and you have a nice open stretch of road (I dont want you staring at your rpms and rear ending someone) do this test again and report back which gear you WERE in, what your RPMs were, and then where it stopped on the way down to 1k. Same as you posted above but with more detail. I'll try to reproduce this in my car as well.

 

ok I will!!!!!! Thanks alot guys

 

I think it's the rev-matching feature he's talking about, and not "sticking". I personally don't like this feature, but then there's nothing we can do about it.

 

Well if thats what it is the rev-matching ( I hope thats all ) then I can't imagine why they tried a different guage cluster and then when I called yesterday they told me that all TLs do this but we are looking into it. Why are they looking it to this if this is what is supost to happen. I will let you all know what happens and im going to another dealership and test drive one.


Please anyone that has a 6mt let me know if this is happening.

 

My 04 TL 6MT did that for rev-match (to the remaining gears that you could potentially engage), until it hits 800 RPM.

 

It's not a first complain on Acura TLC and Acura-Trained service technicians btw just

I didn't notice any RPM's sticking , but next drive I'll check it, and let you know.

 

It is rev matching. If you hit the gas again or the brake, it will drop the revs back down to idle. Also, it won't hang there for more than 3 seconds.

 

OK J-roc, I specifically checked on my way home tonight (forgot yesterday) and my 6MT only stops ONCE on the way down to IDLE.

In Second gear I revved it to 6000 rpm and then engaged the clutch and got off thre gas. It dropped to approx 4500 ropm and sat there for 2 seconds, then dropped to 1000rpm.
Then after another light on another straightaway, I took it to 5000rpm in 3rd and did the same thing. It dropped to ~3500rpm and sat for 2 seconds, but then when it dropped it dropped all the way to IDLE.

So if your sure your car is sticking at multiple points on the way down then something is wrong with it.

 

It should drop once, to match the revs needed to hold the road speed you are at in the next highest gear when you engaged the clutch.

My 05 does it too. At first it was annoying but you get used to it. I believe it is the ULEV rating for emissions.

My 05 is a 5AT so I don't personally experience this, but your comment rang a bell. I've heard that many MT cars (from all manufacturers) are slower to lose revs and that somehow it's due to emissions control.

 

J-roc:

I experience the same as Casper. It pauses at a certain rpm range and then drops. From my experience, it should not be 'sticking' at any other points.

 

UPDATE: I checked on my way home tonight and my 6MT RPM's didn't stops on the way down to IDLE. When I'm doing up- shifting RPM's stay less than second & after that start go down to IDLE. But on daily shifting, I change gear before RPM start go down to IDLE. The same like use to on 95 GS-R.

 

Well, I got my car back and it's the rev matching. The sevice guy took me for a ride in is car and it did the same thing. But his stopped twice and he said that's normal. So I guess I will have to live with it. Thanks guys.

 

First car I ever experienced something like this was a 1977 Datsun 280Z fuel injected motor. Seems Datsun (now Nissan for you younger folks) had to hold the revs from dropping too quickly to reduce the chance of backfires and screw up its emissions tests.

Unfortunately this totally made the car a bitch to drive when I autoX-ed it or road raced it because it basically kept the throttle open for just long enough to screw you up when you let off the gas. It didn't matter whether the clutch was depressed or not.

After many calls to Datsun saying it was normal which I believed after talking to other people I finally found some info on defeating it. What a difference it made in the drivability of the car.

I personally think the rev-matching BS is a load of feces. I think it is emissions related and I'll explain why I don't believe the rev-matching. First off if it IS rev matching, it will be the same whether the car is cold or not. It will also change EACH TIME you shift based on your road speed because each time you shift unless you shift at the EXACT same point, the rpms required to rev match will change as will the point needed to rev match between each successive gear shift.

For example the rev matching drops need to be less and less as your road speed increases(which forces you to be in the higher gears) because as you go up in the gears the rpm drop between each gear becomes less. For example you drop more revs on the 1->2 shift than you would on the 5->6 shift. So if you were to shift from 5->6 virtually no rev matching would be needed because the rpm drop is minimal. You start with about a 37% drop and end up with about a 22% drop in rpms.

From what it sounds like is that the rpms drop by a set amount or to a certain rpm. If this is in fact rev matching (which I HIGHLY doubt) the rpm drop should vary based on the difference in gear ratios between each gear. For example the revs should drop about 37% on the 1>2 shift and about 22% on the 5>6 shift and not just to a certain rpm! Think about it for a minute and you should understand it. Let me know if you don't and I'll try and explain it another way. What we are looking for is a ratio based on rpms and not an absolute or static rpm to be used for rev matching.

 

i just tried it last saturday. going from 6000 RPM in 3rd it stopped 3 times before i got to the idle. looks like it stops for 4th, 5th and 6th gear. maybe there is difference between 04 and 05 models ? mine is 05.
