Gearbox oil pushes of of box by the gear leavers when driving

Thanks. I will check breather first.

Okay.

I would like to thank you for your help and service. As I could not find the problem I decided to remove the transmission for the car. I then took it in to a transmission center who in turn explained the seals inside must have packed up. Cost was a few thousand bucks (South Africa)but the time was the problem so I took it back home on further inspection I noticed the filling fluid nut had not been touched as I could see it was corroded and one could see it had not been opened for a long time. At this time I wondered how the mechanical workshop had filled with gearbox fluid as I was charged for five liters of fluid.I then realized they had put five liters of oil into the box by removing the gear shift. I turned box on its side and let the fluid run out and left it for some time to drip dry as I would put it. Thereafter fitted it back in place managed to open side filler nut added half a pint to box and over was my trouble done over 200km and no fluid coming out gear lever at all.

Thanks.
