Hi all, my car seems to drip gearbox oil out, probably only a couple of drops each night, but my mums going mad about the drive and i dont want it all to leak out!

So just wondering if theres any common places,iv got it on axle stands atm, and there seems to be some clinging to the bottom of the sump, and alot around the gearbox mount, i suppose it could be coming from anywhere then shifting whilst im driving, iv cleaned it all up and hoping i can see a drip coming from somewhere later onm., But just wondering the normal places to check?

Also when on axle stands i started it up and put it in gear to see if any would coime out then.

I noticed the o/s/f wheels spinning quicker than the backs, and the n/s/f hardly spinning at all, and both the rears turning at the same rate. Is this normal or would it indicate another problem? Hope some one can help Thanks for reading.
