Defender transmission leak

Flatty, sounds like the transfer case intermediate shaft o rings. It is a transfer out job to repair.

Once it left a bit on the road while I was idling waiting for a gate to open but that is all. I have just checked the level and used 500ml in 8-9000 kms. This amount should leave a rather large mess wouldn’t you think? What is the most likely cause and how do I fix it? By the way I checked the gear box as well it was OK & didn't appear over full. While parked it barley leaves a couple of drops.
Thanks in advance Flatty

Check the front prop shaft seal. Mine had a leak and it worked back to the rear. When I looked underneath there were usually drops forming on the bolts on the bottom of the case. Simple fix by putting in a new seal. Since then no problems. Just leaks everywhere else like normal

Believe it or not they can leak from the bolts!.
Some of the bolts actually go into the fluid cavity, Blind bolts , the oil then wicks past the bolt threads and forms on the heads. You might have to drop the oil, and coat the bolts with thread sealer.

Got a leak in my transmission

Cleaned it up then left it to see where it coming from

Appears to be two areas
1) the joint in the trasmission where two parts of metal come together ( on left of attached pic)
2) seeping through the two bottom bolts in the top of the picture

I thought of tightening the bolts that hold the to parts together ( ie trying to tighten up the seal ) and also tighten up the two seeping bolts .......but I don't want to over tighten and make things worse

This is not a huge leak .....but after a few days there is transmission fluid on the exhaust pipe and I'm not happy about that ....Also worried that any loss of transmission fluid may not be good for the moving metal bits in side .......

Hope the above is understandable as I'm not mechanically minded so not entirely sure what I'm looking at .
