    Downshift problem from 5th to 4tg - Manual 5sp Transmission

    Hi


    I have quite a annoying problem when driving, I have no troubles shifting 3-4-5, but when I want to downshift from 5 to 4, mostly it doesn't let me, when I shift even a little toward 3 and then back to 4, it works as as it should. Also with the engine off and not moving it more less shifts as is should
    Yesterday I was also informed by my technician that my flex discs are in need of replacement, but i dont know if this issues are related.

    And yes, I have a 2004 model CTS, 2.6L, MANUAL 5-speed transmission

    Thanks for your advice

    Im not sure but is the clutch hydraulic? If so it might be the slave cylinder.

    Manual clutches are operated by cable at the top of the bellhousing with an armature, hydraulic ones have a hydraulic cylinder on top of them, if its quite hard to push the clutch in odds are its a cable one.

    I know its a hydraulic clutch dealership says so. So, it could be your slave cylinder or master cylinder.

    Could it be the "synchro" ?

    Why would a slave or master cylinder problem only affect one specific downshift, but not affect any other shift? That doesn't make sense.

    It's more likely that the 4th gear synchro is going bad. chlapec10, do you rev match your downshifts? If not, that makes the synchros work that much harder every time you downshift, which will wear them out over time. If you're not rev matching, then start learning how to do so. Also, try this: When you want to downshift from 5th to 4th, push the clutch in and pull the lever out of 5th. Release the clutch pedal for just a second, then push the clutch pedal in and go to 4th.

    Honestly do not know what it means... but I downshift regularly than on any other car..

    When you want to downshift from 5th to 4th, push the clutch in and pull the lever out of 5th. Release the clutch pedal for just a second, then push the clutch pedal in and go to 4th.
    Thanks for the interesting tip, I will try it today and let you know how it goes

    Re: Downshift problem from 5th to 4tg - Manual 5sp Transmission

    Rev matching is blipping the throttle in between gears as you downshift so that you match the revs of the engine to the revs of the transmission.

    If you're downshifting to accelerate, it's pretty easy - you just put the clutch in, blip the gas to raise the RPMs and shift to the lower gear, then let the clutch pedal out (hopefully with the RPMs about where they need to be in the new gear).

    If you're downshifting while braking, you have to heel-toe in order to blip the throttle while still maintaining pressure on the brake pedal.

    yes.. I do that, but honestly I am not paying a lot of attention to it and it I might be doing it all the time mostly while accelerating...

    I will let you know about how the downshifting with interrupted clutch pressing goes... did not drive today

    ok, so releasing and pressing the clutch did not change a thing... still had to shift towards 3 to able to shift to 4...
