Well, car needed new gearbox (we thought) so bought a new gearbox £260 as old one jumped out of third gear.. well when we got the old box out there was a spark plug wedged in the gap for the gear selector so we assume that was it.. instead of the hassel we're putting the new one back in. We swapped the old hydralic thurst bearing with the new one as the new one was quite corroded. So now to put the original one back in we need to know if its sealed or not sealed to fit it back on the bar in place. I cant really describe it but thats the problem lol
