    Unfortunately I don't think it's doing anything there that it wasn't designed to do. I say "unfortunately", because if that were the case then maybe there would be a fix. But they aren't going to fix what has been done intentionally.

    Exactly. Much better way of wording what i was trying to say. My 09 6MT does the same thing. Very annoying, and the only explanation i could get from the tech at the dealer was "maybe its trying to anticipate a downshift" Ive only ever owned MT's, I know how to drive one.

    It also seems that if i have to brake hard, the RPM's go higher. Anyone else noticed this?

    Probaly have to here how high up its going. Do not know if the computer in the car is compensating to try engage cluth and trans for smoother transmission. In automatics Yaw sensor is used along with calclated engine lode, throttle references and speeds all to provide smoothest shifting. But I do not know if this applies to Manual trans mission. I have an automatic. I will look into it because i am curious also. Could also fuel ration condition. Extra fuel being dumped under load and then take away the load. Extra fuel.

    Yes, Mine does this. :mad: I am sure it is because of the electronic throttle.

    Try just punching the throttle and let go, and you'll see the engine will start revving just after you let go of the throttle... Evidence that it is the delay in the electronics that doesn't notice you let off the throttle when shifting.

    This is the only thing I don't like about my new Toy! :D

    :burnrubber:I have a little different view on the problem statement for this discussion.

    If I drive it slow and short shift the manual 5 speed it is just like any of the other manual trans trucks I have driven.

    But if I rev it up and then try to shift, there is what feels like the engine reving after I let up on the throttle to shift. The sequence is I let up on the throttle and then push the clutch in to shift and I get this apparent additional rev up with the clutch pushed in. There is some vibration you can feel thru the floor board. I can feel that the truck does not like me to do this so I have adjusted my shift habit to letting all the way up on the throttle well before I shift to where I feel the truck slow down some then push the clutch in to shift. I don't like to drive this way so I just short shift it and don't rev it up and shift fast unless there is a real good reason to push the truck.

    I think it is the ECU trying to burn up the fuel in the engine for emissions compliance. :sadviolin::sadviolin:

    My 07 does this and it is substantially worse than my 05 was. I talked to my friend (service writer at toyota) about it and he did some research. Said it was an emissions control thing having to do with burning the excess fuel going from load to no-load condition for a shift. I could give two shits at 14 mpg so I asked about reprogramming the ECU. He said it couldn't be done. Also asked Gadget about it, and he confirmed. I put the short shifter in anyway and I either got used to it or it learned my style as someone suggested, but either way, it doesn't bother me much anymore.

    Mine does this too. Keeps the revs up between gears and I do also sense a faster idle than I thought would be correct. I got used to it but truck dosen't shift as smoothly as it would if it didnt do this.

    Normal for these Tacomas. Not normal for a typical manual transmission equipped vehicle.

    In my opinion, the rise in RPM between shifts is totally unacceptable. Not only is it annoying, but its causes wear on the clutch. Anytime there is a difference in speed between the clutch, transmission shaft and flywheel , there will be wear. Normally , I would not worry about that small amount of wear, but my clutch wore out at 5000 miles on my new 2009. Yes, I can drive a clutch, 4 previous trucks, all got more tham 161,000 miles and never needed a clutch on any.
    There are Luk clutches and Aisin clutches in these trucks, Apparently the Luk clutches are the problem.

    Yep. The throttle reaction of this truck in just about every way is unacceptable.

    Give Toyota a call and complain about it. Maybe if enough of us complain, they will make some changes in the future at least.

    yes I have a manual but no my engine doesn't rev when coming to a stop...its called downshifting and matching the rpm's to the lower gear...its a racing thing and something I have been doing on all my manual vehicles since I 1st learned how to drive manual...

    no when accelerating my rpms do not bump up maybe yours do cause your not balancing the throttle and clutch when shifting...

    I too have a TRD S/C so my throws are a lot shorter than stock (which I like...:D) but I can slam gears all day long and not have a single problem...

    When I shift from 2nd to 3rd, the RPMs rev higher a little right after I press the clutch.

    When my dad was teaching me to drive manual, he would always be like "STOP DOING THAT, YOU DO IT EVERY TIME".

    The solution is to let your foot off the gas before you press the clutch. Then bring it back fast enough before the RPMs drop to idle.

    It's very hard to match your RPMs quickly. Electronic throttle sucks.

    I'm not sure if electronic throttles suck, or if just this electronic throttle sucks.

    My 2008 does the samething but worse, when I slow down in traffic and the rpm gets to 1300 it just stays there and powers the truck. When I put the clutch in and put it in neutral the rpm stays at 1300 until I come to a stop and then drops to 800. You can't shift into 2nd when going around a corner at slow speed because the truck will speed up instead of slowing you down. I have had it into the dealer twice and they agree it does have this problem but say that's the way it's suppose to be. This is bullshit. This is my third tacoma and the first one to do this and it will be my last.

    Mine does the same thing. While it is straight retarded, it is part of the design. They just expect you to push the clutch in sooner than you would with any other vehicle.

    When I first got my Tacoma, I took it back in complaining about that problem. They claimed they'd never heard of that before. A tech took it for a ride, and I went with him to point it out. He acknowledged that it was indeed doing that, and seemed to agree that he didn't like it, but that was what the software was making it do.

    I also called and complained to Toyota about it. This was all back in 2007. I tried to relate it to a safety issue, because there were times when I was slowing down, it was reach a certain RPM, and suddenly it was no longer slowing down. It would almost even accelerate a bit on its own.

    It doesn't really happen to me anymore because I've gotten used to it and know I need to take it out of gear a lot sooner than any other vehicle. But there are still other issues with this dumbass computer controlled throttle that I will never be able to adjust to. It really pisses me off.

    When it's time for a new vehicle, I will test drive another Tacoma. If the new ones do the same thing, I'll look at something else. I don't want an automatic.

    My new 12 is doing exactly what all of yours are doing and I think it sucks. A powerful engine like this should drop revs as soon as you let off the gas and I think it's the drive by wire BS...programming, whatever. I don't like it, but I can adapt. Anyone ever figure out a way to avoid this, reprogram, ecu reflash...something?
