  • Type of project: Bus modification


    Name of project: Volvo 9900HD RTM gearbox modification and improvements (it works with the beta version of the Volvo, which is on the following folder: "volvo9900new". IT WILL NOT work with the other version of the 9900 which has the Krueger display.)


    Involved persons: Me


    Details: This is a mod which improves the gearbox and other little things.


    Copyright: You can do whatever you want, this is just a little improvement.


    Pictures/videos: ---


    What's changed:
    - Edited the ratios, now it has the ratios of the ZF AS Tronic 12 (called by Volvo "i-Shift 12")
    - Added weight to the bus, now it weight is 19 t (according to the official Volvo 9900 page)
    - Improved the brakes


    The bus now appears as "9900HD RTM ZF AS Tronic 12"

    P.S:
    I'm currently working on the lights system, but it isn't included in this package.
    In the future I'll update the pack.

    Concerning constructive feedback:


    I am/We are receptive to every kind of constructive feedback. It must not hurt me/us and must not diminish my/our work.
    Please write your feedback to my/our work so, as to be

    • precise and clear, thus not vague or emotional
    • analytical and rational, thus properly researched and convenient, not on impulse
    • solution-orientated, thus, if applicable, attached with counterproposals, consequences and implications.
    • Please write in ENGLISH because I don't speak German.


    Since I am glad about any kind of compliment of my work, a balanced ratio of positive and negative feedback is greatly appreciated.

  • Looks good! One of the problems I had with the normal Volvo 9900, was that when the bus shifted gears up, the passengers started to moan about my driving style. Do this happen on this version?

  • Yes, but seems at the moment that there's not a solution, because of the gearbox is semiautomatic and it takes a few seconds to change from a gear to another

    ;)

    The functioning is the same of the previous gearbox.
    The difference is with the ratios, which are different
