Where do I put the transmission oil on my mustang 95'?

I do not know where do you the transmission oil change n my car. I have a '95 Ford Mustang and I need help!

IF ONLY there was a book, like an 'Owners'-Manual', available from your Ford dealer, or on eBay, which could help you out here? Or a workshop manual, from the same sources? Or a guy who worked at a business premises, who did nothing but 'work' on 'cars' all day long? The sort of guy or girl who could find where to drain and fill the oil in a gearbox, just by say, lifting the car on a two-post lift, and looking at said gearbox? I'd call them 'Mechanics', and they'd work in a 'garage'.

(Sorry - I think you can tell my allegiance is with GM).
