Gearbox oil change

[GM6VXB]

Thanks both.
Managed to get further under the car (not good when you have Labirinthitus) and yes it goes into the belll housing.
Had me a bit confused at first as feeling in the hole with fingers I thought I could feel a gear, now know it was
the flywheel !!.

Will underfill the gearbox as recommended.
Back axle is next on the list, plus good inspection of UJ and flexible coupler.

Thanks again.

Martin.
