Help ! gear box fill point ?

Hello People
 
First post of many I hope, maybe less asking for help !
 
I have a Mazda MX3 1.8 V6 Manual and in a stupid move removed the sump plug and removed all the oil from the, wait for it... gear box.... not the sump :(
 
This is more of a problem as the 2... Yes TWO ! Chilton books I have ordered, neither has turned up and I don’t know where the gearbox fill point is... any help would be great
 
Thank you
 
Chris

The speedo driven gear assembly is the fill hole. It takes 3 quarts or to the top of the gear.
