Can changing the motor oil have any effect on the gearbox oil or is the following just a co-incedence? I changed the motor oil (perhaps it's too thin 15/40on motor) and I have noticed a drop or two of oil on the road each morning. Directly above where the drop was I noticed some dirty old oil pooling on the bottom of the gearbox ready to drop. I guess I can have the gearbox oil changed too now, but I am perplexed as to why it started happening straight after the motor oil change? The vehicle is an early 80's l300

Could be spillage or a leak from the motor dripping down onto the gearbox, you will be surprised how far oil will travel from the source!!
But apart from that, no changing the engine oil will not make the gearbox leak!

sounds like you spilt oil in that area from when you removed the oil filter...

If its a manual then you may have a leak past the rear main seal on the crank which is leaking out of the drain hole in the bellhousing. Yes a thinner oil will accentuate the leak. Otherwise you are just a grub and leaked oil everywhere :-) LOL.....Cheers BradLife is short- but there's always time for a yarda.

The only oil spilt was the old down my arm when the filter & plug was undone, otherwise yes it is a manual and yes thank for that info because the oil leaking is old and black in comparison to the new stuff

As well as all the above, if you changed the filter make sure you havent left the filter rubber seal stuck to the filter sealing face and screwed the new filter on top of it. If this happens the pressure will blow the old seal out and you can lose all your oil. For anybody who do there own
services always check you havent left the old seal stuck on as I have seen a couple of seized engines because of it.

gearbox oil has a distinct smell about it. I suggest you get some on your figer and get it right up ya nose. Maybe it is not even gearbox oil, you would be surprised how far it will travel along a driveline.
