Its been brought up a few times...But can anyone explain why my car can do this and other 3.0s can't?

copy and paste didn't work

 

 

did u peg that? or just go past redline.

our cars can do that because there is no rev limiter I don't think I've taken it a little past 6.5k myself nothing happened... so taking it to what was that 6900 is fine too.

I believe autos got the rev limiter. or just the 3.0 autos.. which is all of them except people who got swaps.

EDIT... looks like someone beat me to to posting that pic.]

EDITx2: oh ur an auto too... 2.3 auto?? I guess just the 3.0s got the limiter and 2.2 2.3 dont

 

Thank you for hosting.

 

Thats my shift point for 1st gear to 2nd gear with the car shifting by itself. Others have said theirs shifted way before that. Mine's a 3.0 just like theirs. So I dunno.

 

oh... perhaps u got something broke... or u wore something out ??

 

Thats what I'm trying to figure out.

 

hmmmm this could mean ur tranny is going to go sometime soon.. that it can't switch gears until it revs THAT high. just some deductive reasoning... perhaps u already thought of that though.

 

When I'm driving normal it shifts fine. Its only when I lay the hammer down that it shits at that range.

 

sry i dunno bro...

early sign? but apparently normal driving conditions ur car is in good working order... so, im not sure what else influences shift point on an auto tranny. a sensor malfunction? perhaps the helms manual that aaron is hosting will tell the story.

 

if i drive hard then YES mine too

 

Mine will go up to about there if i'm doing it manually before it hits the limiter


Also Honda's tachs are usually 400-500 RPM off

 

also, maybe it has something to do w/ when you changed the gauges

 

yes perhaps ur tach is off from the installation of the gauges plus the supposed honda tach margin of error.

 

oh.. yeah I asked you about that earlier, but even though it does say that the speedomoter wouldn't lie too. Mine shifts at a little over 6000 Rpm, and it's at about 38 mph, but his does it at almost 7000 rpm and at about 42 mph which matches up with the increase in RPM... do you have I/H/E on your car? If so that's probably the reason for it. The increase in power probably makes it rev higher faster so the tranny doesn't think it's gonna go that high that fast. That's the only thing I can think of.

Edit: oh yeah and I thought I would make a comment about the rev limiter that justchillin mentioned. If I leave the car in "first" then at a little over 7000 RPM the tach will "bounce" back and forth between 6500 and 7200 rpms. THAT would be the rev limiter at work.

 

but what if tire diameter is smaller or larger than stock? that affects ur speedo, and not tach. well it does, but the corrilation is not linear.

there are a lot of factors u can't just match up mine shifts at this rpm and that equals this mph... so on his car blah blah... im not being an ass, just that there are to many variables use that as a basis.

 

oh yeah. that's true. I hadn't thought about the tire factor. It's still higher because from teh vid it sounds like the engine in my car would sound at teh same RPm and mine never shifts that high unless I force it to. I still think it's teh fact that he has the mods on there, and the tranny can't keep up with the increase in acceleration.

 

if the ECU was reset after mod install which i am sure it was... ECU should be able adjust the transmission shifting? i don't know, just a thought. well others shift high as casper said.

so either it isn't that high... or the rev limiter is not so sensative/are not adapted as the ECU is when reset.

 

got rice its ur tranny. mine was doing that intill they changed the tranny. watch it might mess up your motor. if you still have a warranty take it in.

 

hmm a second vote for the tranny. but then again sometimes we are way off... sometimes dead on.

 

well mine was doing that and didnt take it in the after a while when i would get on it it wouldn't shift till it bounced off the rev limiter. thats why i am thinkin tranny

 

My 3.0 start doing that after a few upgrade i did....intake...denso iriduim spark plugs....and royle purple 10W30. I'm thinking its the upgrade....it shift fine with i'm driving normal....but it over rev like that on first and maybe 2nd when i put the padle to the metal too.

 

I don't think it's the tranny

 

BINGO!!!

Look closely at these gauges and compare it to the stock tach. Those gauges have the 7K RPM in the 3 o'clock position. On the stock tach the 7K is in the 4-5 o'clock position, about where the green light is in the picture. So on the stock gauges, the needle in the picture would be registering a little over 6300 RPM, which just so happens to be the redline for the 99 3.0. Fuel cutoff occurrs at 6600 RPM so, in that picture, you're not there yet.

 

that's exactly what I was thinking

 

Anyone have a shot of a stock guage cluster? This cluster was made for a CL...So it would be odd if it was off like that.

As per the other questions...Stock rims capet upgraded suspension, intake, exhaust, denso iridium plugs, one or two other minor things that I don't think would make any difference.

Thanx for everyone's input so far.

 

that cluster was actually made for an accord if i'm not mistaken

 

My gauges are off by a little too!!!

 

I'm 90% certain the advertisement for it on E Bay said for a 97-99 CL. However, I have no doubts its the same as the accord cluster. So you're probably right.

My mph is correct though. I checked it against a Police speed detector thing on the side of the road.

 

here's a pic of the stock gauge cluter and covers.:



edit: yep it looks like it is the covers. As you can see in the stock gauge cluster the 7000 rpm mark appears slightly lower than the Neutral light for the gear selection display, whereas in teh white gauges it appears slightly ABOVE the Neutral light. The truth has been discovered.

 

Sweet! So my shit isn't broke! Good to know. Thanx.
