Transmission Fluid Weeping -easy fix?

While under the 90 yesterday, doing a bit of a clean ahead of applying Dinitrol / POR15 next week, I noticed what appears to be a weeping of clutch fluid between the two halves of the bell housing.

I'm not a mechanic so I hope I have this right, but hopefully you can see on the picture where I mean (this is after I cleaned the oil away). Its weeping through the seam and not the drain plug on the left hand side.

Is this likely to be because of fluid overfill at the factory? the truck is coming up to three years old, 17,000 miles only and as far as Im aware (we are not the first owners) it will not have had any work done on the clutch etc and no change of fluids required in the maintenance schedule.

Is it likely to be a simple remedy of tightening the bolts, adjusting the fluid to the correct (2.2l?) level if overfilled and job done or is there a possible need to replace a seal or something?

Its booked in to the local LR dealers for inspection next week and I want to make sure I ask the right questions

Any help gratefully received.

I should add that I have no other issues with gear selection (other than the usual 1st to 2nd slight resistance) so no apparent misalignment of gears etc and the clutch is fine as the truck gets very light use)

Thanks,
Paul

If it is indeed hydraulic fluid then the clutch slave cylinder seals are the likely candidate, to get to the cylinder on a Puma means a gearbox out job. I would check the fluid level in the clutch master cylinder reservoir and monitor accordingly. Sure it's not oil? Steve.

It could be the clutch slave cylinder which is inside the bel housing somewhere and requires the gearbox removing to replace. So definitely get it done under warranty whilst you still have it.

Thanks both

Just did a bit of reading up on this after you posted and it certainly sounds like it is unfortunately the CSC. Its definitely not engine oil (too clear and not viscous enough). What a pain if its gear box removal time and with so little mileage

Its going to the dealers this afternoon now, which is only a few miles away, so they can get it up on their lift & take a good look. I'll feed back what they say.

Good job I spotted it while still under warranty I suppose.

Guy Salmon at Ascot were extremely helpful and have calmed my fears of a transmission fluid leak - it was in fact condensate from the air con

Felt a bit silly but better safe than sorry

Apparently the AC vents above the gear box housing and was dripping exactly around the point at which the two bell housing halves meet and looks just like a leak when its just a small amount.

Having run the air con fully on for a half hour journey and reinspected there is a lot more fluid (obviously) now dripping around that point and its clearly water not oil.

Few!!

Time to now get on with protecting the underside as intended and say sorry to 'Ermintrude' for doubting her reliability
