Hi, I'm looking at getting gearbox oil and filter changed and it looks like a bit of a challenge for an enthusiastic amateur like me.

I'm looking for an independent garage to get this job done but not to far away from home. Looking at Cambridge, Milton Keynes, Peterborough, Hatfield area as I live in Sandy, Bedfordshire.

I'm guessing is going to cost around £300'ish. Am I on the right track?

Thanks

Steve.
