  1. Hello Good afternoon:wink:, first of all say hello and thank you for being able to participate in this forum. Secondly, comment that I am the owner of a megane rs 3, and recently I have had problems with the gearbox, basically from 100km/h fifth gear does not engage, the lever remains in the fifth gear position but does not engage. Below 100km/h everything is normal.... (gearbox PK4018
    It is a car that I do not mistreat, I take great care of it, it has 120,000 km and I am desperate:tired:, I don't know if removing the battery I can see something to solve

    Hi and welcome.
    I think you will find that the bulk ring is worn, its sort of a common problem, mine did it in 4th gear, but my car was used a lot on track.
    In the end i couldn't get 4th at all, then 3rd started getting hard to engage, so pulled the box, stripped it and replaced the whole cluster.

  4. Hi Manel! This is an english forum so, please, write in english!:grinning::grinning:
    The gearbox oil must be a GL4 75W80. You´ll need about 2L. Honestly, I don´t think you solve the problem with an oil change. Maybe I´m wrong. Luck!!
