Help With The Transmission Please!

[jogirl]

Hi there- having a few problems with my 94 nissan bluebird. After repair at the mechanics, the transmission fluid seems to have drained itself in fast fashion- where is the bung to refill this, as i also would like to make sure its screwed on right ?

any web pages out there that will give me detailed location- i am female, in dire need of a net mechanic...so these links (if theres any) would be very helpful

i have followed the puddle under the car to something sodden and seemingly 'bung-like' -if the whole underside of the transmission is oiled (and ready to fry) could it be more than just a leak???ahhhh so many questions- HELP!
