At service, it was suggested that something to do with a gearbox seal (I think he called it something like that) was poor and it was losing oil. He pointed it out to me under the car and said it would be ok but needs doing at some point.
Now i've taken some pictures of the offender in question. They're not great but I think it shows the part ok.
Can anyone tell me how much something like this seal is going to set me back? It doesn't look like a difficult job to replace (though i'd probably get garage to do it).
Any ideas on prices etc so I can get prepared? Many thanks
