R33 GTS-T 5 Speed - Update Final

Saturday morning drove out to Stewart's, i had been stressing all week with what it could be and also how much it would cost to sort out. Thoughts going through my head of putting the std box back in or rebuilding the R33 box with new bearings i was not in a good frame of mind.
Arrived and we chucked it on the hoist to have a look, a leak from the box had started and we wanted to fix. It was coming from the drain plug so we pulled the oil out and put some sealer round the plug then filled it up with some new oil, originally we were just going to put the old oil back in but it was to much of a pain and Stewart said he would shout me some fresh oil which was nice of him.

We looked over the box and Stewart suggested we should check to see the clearances over the box, i thought this was a little strange and maybe some way of not looking at what Andrew had suggested but went along with it anyway. He was feeling around the top of the gearbox and saying that it the box hits the transmission tunnel the noise can transfer through to the cabin from the box. He found on top of the box where there is some bracing on the transmission tunnel that he could not get his fingers in and suggested trying some wire to see if it passed through - it did not.

We had changed the R33 mount that came with the box over to my old mount from the S14 as it was a nismo item and i wanted to use it if i could. We loosened the gearbox mount and put 4 thick washers between the bracket that holds the mount and bolts onto the chassis and the chassis.
After tightening up we were able to push the box up which we had not been able to do previously, this was a good sign and we cleaned everything up and dropped if off the hoist so i could take it for a test drive.

Out the road and immediately i notice how quiet that box is, i think it might be to good to be true and with the new oil it might have quietened it down a bit so took it for a longer 20min drive.

Fixed :)

Went back and let Stewart know and he was very pleased, headed off and it was so good that everything was OK now the heavy shoulders that i have been feeling all week went away and i was able to enjoy the car.
James came round and latter that day we did some road testing with the new box and it was just perfect.
