225 Fifth gear crunch when hot? Meg 225

Discussion in 'Mechanical - Engine, Gearbox, Exhaust etc' started by finlay.miller, May 23, 2016.

  1. Looking for a bit of guidance here, car has developed a slight crunch in fifth gear at high revs..
    Gearbox oil has not long been done as the diff seals were changed recently. Every other gear is silky smooth, no issue with 5th on down changes and only seems to occur once the box is warm?
    Is the syncro nackered or could it be something else?

    Its a megane 225 engine and box with around 55k miles running 270hp and 301lb/ft

    Cheers, Finlay

  2. I've recently had the same thing but with 3rd gear on my Meg 175, was told it was the syncro and that I needed a new gearbox.
    Heading to 3D transmissions on Wednesday to get it checked out.

  3. @OscarLomax let me know how it goes! Need a diff etc anyway so i guess its a good time to do so if the box needs reconditioned.
