    Wrangler needs a new gearbox
    Answered by Graham Smith · 5 November 2015

    There's no reason to be putting oil in the gearbox, so the oil should still be the original factory fill. If you want you could drain a sample of the oil and have it analysed to identify what it is. I suspect the problem is related to its heavy off-road use rather than the wrong oil being used.
