    Default Manual Transmission problem in 7th gen civic

    Need experts opinion on VTI civic manual tranny. There is a knocking sound when the clutch is not pressed, one can hear it all the time irrespective of being hot or cold.

    A little history:
    When I bought this car some 2 years back it was difficult to shift to 2nd gear and it always shifted with a buzzing sound and there was almost no power in the 2nd gear. The gear box was opened by a mechanic but he couldn't fix it, the problem remained but in a few months it dissappeared by itself. But since then the knocking sound started. And its very difficult to put it in reverse gear.

    Questions:

    1. Is it time to replace the gear box?
    2. Do I need to change the clutch plate as well with a tranmission replacement?
    3. Can I replace the manual with an auto tranny? What parts would I need to replace with it? Infact, when I checked in Peshawar, the auto transmission costs less than the manual ones so i thought why not replace it with a prosmetic one, if it can be done without any problems

    So today I replaced the Zic transmission fluid with Caltex Delo Gold motor oil. The knocking from gear box is like 20% decreased (if its not psychological) but its still there. Gears change normal as before except the reverse (feels like reversing a Bedford truck). Looking for more suggestions on what to try next..

    synchronizers = karha (bracelet)

    if your reverse is crashing then your clutch is not working like it should - the reverse gear has no synchronizer. Try to shift to reverse after 30 seconds of pressing the clutch to ensure the transmission has stopped.

    If it still crashes, replace the rubber pipe on the slave cylinder and recheck.

    Okay, will check with reversing after clutch pressed for 30 sec. So ask the mechanic to check the clutch cylinder and change the karha of reverse gear? Damn hard to get any mechanical work done in Ramadan.

    About the knocking sound? Its almost the same after changing the gear oil. If there is no easy solution to it and it remains without damaging anything else, I can live with it for a few days.

    there is no karha (syncronizer) on the reverse gear, that is why i asked you test it, if you hear it crash, it means the transmission input shaft has not disengaged from the engine - which is the clutch's job.
