Sump plug is center of car, probably easiest to access from the opposite side the exhaust runs down. 

So yes I think passengers side

Good luck James

Should be at the rear of pan. Which will be close to the gearbox mount. 

I think its a 14mm head on the sump plug

Hey James

If trans has a drain plug, it will be on the pan (sump) of transmission.

if it does not , you would need to remove the pan. You may need a replacement gasket if you break or crush the existing one.

Make sure you fill with the correct specification oil, as this will affect the clutch inside the torque converter and could possibly do more damage than good.

Hope that helps
