    Hey all. Some background: I recently purchased a Civic Type R which is my first manual car. I borrowed a 1999 ford escort for a few months to learn on, but it was worn to hell and back, meaning the clutch on it was very janky and hard to feel for.

    My question is in regards to smoothly shifting gears in relation to acceleration. I notice that if I want a perfectly smooth shift with no lurching or jolting, I have to shift somewhat slowly in order to give the engine enough time for the revs to go down. I can do this easily and consistently and it leads to a very smooth shifting experience. However, if I'm really wanting to accelerate quickly, I dump the clutch quicker and press the throttle a bit quicker so that it catches in a more abrupt manner. This gives me the result I want (quick acceleration) but it seems rough.

    Is it normal and/or unavoidable to have small jolts between shifts when accelerating quickly?

    Quite frankly, yes. As with all things, practice makes perfect. The more you practice and make tiny subconscious adjustments, the smoother all shifting will become. Eventually your body will be prepared for the jolt and will counteract it accordingly. You wont even notice it anymore but your passengers will.

    Yes, learning to drive a manual will wear out your clutch faster than someone who knows what they are doing from the get go, but i wouldnt worry too much about it.

    It is normal to have small jolts between shifts when accelerating quickly.

    That being said, if I'm trying to accelerate quickly, I'm usually not shifting. I'm running up the RPMs until redline.

    I do find shifting quickly, getting back on the gas, and smoothly letting out the clutch helps with jolts between shifts.

    Oh absolutely. If I'm trying to accelerate quickly I'll always go to the redline. The longer between shifting the better!

    It's because this car still has some slight rev hang. It can be tricky to shift quick but with practice it's easy. Practice getting really good at shifting without any gas. This will help you build muscle memory of getting to the engagement point quickly.

    As I'm almost off of the gas to shift, I will quickly clutch in and quickly clutch out right before the engagement point. My leg will then "hitch" or slow down at the bite point to smooth out the engagement. Once I feel the clutch is almost fully engaged, I'll gradually apply throttle.

    Some mistakes I made as a novice manual transmission driver
    -Clutching in with too much throttle applied
    -Clutching out too fast past the engagement / bite point
    -Applying throttle before the clutch is engaged properly

    What you're describing is something called rev hang which plagues the 10th gen civics. To get rid of it you'd have to go aftermarket like Ktuner or something

    Yup. It’s the rev hang that ruins smooth shifting. We should be glad that the rev hang isn’t as bad as it is in the Si’s. Even my 9th gen Si had horrendous rev hang. Is really annoying. Shitty that you have to tune to get rid of it completely. I’ve just learned to live with it and adjust my driving style accordingly. I personally don’t wanna tune until I’m out of warranty. Nothing you can do about it, really.
