Gearbox oil leak

[Gary G]

Ok so i had the gearbox rebuilt by renault due to a leaking seal (took them two days) a while ago and it has STILL leaked everso little ever since lol...but it now appears i have a rather large leak and i have had an oil change recently and wondered weather its gearbox oil or engine oil creating nice patches on the garage floor lol. Does anyone know exactly how to check the gearbox oil? cheers

make sure they have done the drain plug up tight.
or
next to the drain plug there is a seal oil will be coming from here if its leaking s get under the car and have a look there
