Right apologies for lack of photos but it should be easy to follow the steps regardless.. Could this be pinned?
you will need:
3.1 litres of gearbox oil : G 060726A2 (Approx £4 per litre)
Seal: No 085301227 (Approx £4)
Bush: No 001301209 (Aprrox £4)
A length of pipe about 100mm in length and and wide enough to go over the selector rod
Chisel or something similar
Mole grips

step 1.
undo oil drain on the diff just below passenger side driveshaft and remove oil
step 2.
Using a pair of grips/pliers/mole grips get someone to lightly pull at the bush while you tap the back of the bush with a chisel until it comes free. Leaving the seal in tact ensures it does not scratch the rod and they will both come off together.
Here is an image of the bush and seal removed

step 3.
Carefully push the new bush down the selector rod and using your bit of pipe carfully tap it into place.
step 4.
Slide new seal paying particular attention to the part numbers on the rubber seal pointing outwards so they can be seen at all times even when in situ. Use some grease to lubricate the selector rod when doing so and use the metal pipe again and gently tap into position.
Step 5.
From above using a suitable funnel and pipe inserted into the top filling hole about 60mm above the drain hole fill the box with 3.1 litres of oil. Replace the drain plug and give everything a quick check over and a wipe.
So far it seems its stopped my leak and it also seems to have smoothened the selection of second gear. I think there was some play on the rod moving between the bush before hand which occasionally would interfere with a smooth selection of 2nd.
Note: i also used a tiny bit of sealer on the back of the lip of the bush which contacts with the box and used a bit of fine paper to carefully remove a few light scratches on the rod. nothing major, will be fine without these things being done, personal choice.

You reckon it helped the gearchange much then? I changed the bush on my original G40 'box that is now in bits, I assumed that JP would've replaced it on my current 'box when it was rebuilt 2 years ago - but I suspect that's not the case...

If this isn't included in a gearbox rebuild then that's quite annoying - it's fucked on mine too.

I'll put this into the FAQ section shortly...

well they changed the seal but not the bush. said they wouldnt change it unless you asked. which at the time i didnt know about so didnt ask

JP didn't change that metal bush because it's not in the box of replaced parts they gave me back. They did throw in a new drain bung for nothing though.

oh dont get me wrong i think theyre good! very pleased, i didnt request it to be changed so it never did. should be standard procedure though on a rebuild i think.
