Have I overfilled it?

G'day! Just wondering whether any of you blokes can help me please? I decided to drain my tranny and put a new filter and fluid in. '63 Valiant, /6 and 904.

All went well until I refilled it. I checked the FSM and it said 15 pints. We have been metric here since '66 (DUH!) and the conversion I worked out to be 9 litres.

OK, so I put in 5 litres started it and ran thru the pushbuttons and then added the rest.
When I checked the dipstick idling in neutral it shows a little over the word "full" on the dipstick. :violent1:

Will this damage the tranny if i drive it this way?
If so, how do I get the extra pint out of the tranny please?
Hope I'm no the first dope to do this? :silent:

All advice appreciated thanks
Regards
Gary
