Update. After clearing off the muck and upon closer inspection, the fill plug is the t55 torx bit which I currently don't own so I won't be doing an oil change today but at least now I know for sure.

By the looks of they're both square plugs, if squares are commonly used then thats alright. They clearly do the job and they'll last until I replace them with the torx and hex plugs

Hi all, I was under my 2006 defender looking for the gearbox filler and drain plugs and admittedly couldn't for a while but turns out it's because, at least i think, it hasn't got the right plugs. They fit but don't match the appearance of what the workshop manual shows. I've attached a picture for reference, haven't had a chance to clean the muck off yet. Could it be the previous owner not having the right ones on hand or perhaps a gearbox change? I've only recently bought my defender and am quite new to their mechanics so anything any of you can tell me about it will be great.

Thanks for the replies. I'll play it safe seeing as how I've just got my defender and leave it be until it goes to the specialist, I'll give it run around the village so I don't have to use the higher gears. I'm planning on putting some new oil in the gearbox since I don't know how long it's been leaking for and how much is left. I'll keep all this info in mind for when it does go in and I can work out a plan with the specialist. All part of the fun in owning a defender

I'm thinking you might be right. The engine did seem to grip the gear again after speeding up briefly. I'm taking it to a specialist garage in a few days for a once over so they'll find out for sure what's going on. Would you say it's still ok to drive around till then so long as I don't go speeds that require the 5th gear?

Hi all, recently bought a 2006 TD5 Defender. Had it for about 3 weeks now, runs just fine generally speaking but today while I was out and about, the 5th gear seemed to 'slip' into neutral and back to 5th while nearing 60mph. Only happened very briefly but I have noticed a minor oil leak from the gearbox, figured they must be related. Going to buy some oil just to top it up since I don't know how much is left anyway but if anyone here has any thoughts on what could be causing the gear slip and what can be done about it, would be a big help. Thanks
