What kind of vehicle are we talking about?

Where it leak coming from?

How heavy is this leak?

clean oil or dirty oil as in engine oil is dirty and gearbox is clean.

Seeems to be leaking at the join across the bottom of gear box the car in question is a seat cordoba.

wouldnt mess about with any of that sort of stuff for plugging leaks.....yet.
If its only 6 months since the re-cons been fitted I would go back to the dude that done it.
See what they have to say.
The leak may be apparent at the bottom, but might be from higher up, is it defo gear box oil?

i assume it is a manual transmission.if so nothing you can buy will stop that leak.firstly how bad is the leak?how often and how much tranny fluid do you add?if it is leaking from the join between the transmission and the engine it is likely the input shaft seal and the trans will have to come out.before doing this have it checked out by a reputable mechanic first.just so you know i have been a licensed mechanic for almost 30 years. cheers
