MY cousin drove a lot of stick shift cars, maybe about 30 or so.. and I let him drive my 07 tc, but he told me that something is wrong with my transmission. He told me that whenever he presses the clutch that my rpm is way too high and takes forever to drop down. I noticed it as well but I have never driven another car before so I was just wondering if it was jsut the tc's that are like that or is it supposed to drop fast when i press the clutch? it really takes a long time for the rpm to drop.. and even when i'm in neutral the rpm doesn't drop right away.

He hasnt driven that many stick shifts then. They all vary in this respect. It is the rotational mass of the internals and flywheel. There is nothing wrong with the car.

If I'm not mistaken, it should idle at about 700rpm. As far as your clutch is concerned, your rpm should go right back to idle when you take you foot off of the clutch. Unless your shifting into another gear, but that's another story. Yes, the rpm should go right back to idle like you were just revving your engine.
This isn't necessarily a transmission problem. Infact, I don't think it's your tranny at all. I think if it were, then your car would stall right after starting it. I don't know what it is for sure though. I would have it checked out. It could be just as simple as your accellerator pedal not communicating with your ecu. That might be why your engine isn't returning to idle as quickly as it should. But it could be more complicated then that. I'm not sure. Have it checked out asap. You don't want to be driving and not be able to shift into neutral and brake.!

yuup! it's normal for tC and other cars. My dad used to have a 1987 Nissan Van and it reacts the same way. The RPM's will just hang there. I try to make it better by fully releasing the gas then stepping in the clutch. It's slow but it makes for a more comfy ride.

there is already a thread about this, there is nothing wrong with your scion, it was designed this way to help beginers (and camry drivers) shift smoother, here is the link

It's fine, as has been mentioned. Also, he's probably sticking on the throttle longer than necessary... the throttles on our tC's are not only sensitive, but also different than other throttles, sorta.

It takes a little getting used to... that's it, though, nothing wrong

I wonder if it has to do with the electronic throttle at all?

It's annoying as heck, but normal for the tC. The ECU is programed to do that, but no one knows for sure why. I wish there was a reflash for the ECU to make it NOT do that.

I always assumed there was a bit of delay in the gas pedal... just let off a tiny bit earlier than you "normally" would and I've had no problems with it.

Deathwish238

I don't see why it's such a big deal? It's not like you're gonna shift faster than it takes the rpms to drop to idle....atleast I can't...

CuRiOuSfIsH

you can match the speeds better and faster that way.

Deathwish238

I thought it's easier to shift smoothly when the rpms do hang a little?

CuRiOuSfIsH

Yes, as a beginner, I think having the engine speed hang around is good b/c it will give time for them to learn to release the clutch properly. I dont find it smooth b/c I tend engage the clutch 500 above the proper RPM..... so the engine always has to drop its speed, and if I let out the clutch just a bit too quickly, it will have a slight tug. Compared to if the RPMs drop and I engage the clutch right when the engine and transmission speeds are proper, then I can let out the clutch faster without any jerkness..... hence why ppl match rev.

I love self proclaimed know-it-all's

please add some insight.

Heavy stock flywheels make the engine maintain momemtum longer between shifts. They allow you to shift more leisurely between each gear without the rpms getting too low. Try driving your car like you're not in a hurry, and you'll see how easy it is to shift.

If you don't like the way it works stock, then get a lightweight flywheel. Revs will rise and fall much more quickly.

And say good bye to the liesurely shifting.

tekstyle

how heavy is the stock flywheel and pressure plate?

web

I believe the flywheel is close to 35-38 lbs. Not sure about the pressure plate.

i can be into the next gear by the time the rpm's drop. i deff shift fast enough to beat them.
