Transmission Questions(fluid change... and other questions)

[Lafiro]

I have a 2007 Sedan Automatic.

I would like to know, from everyone experience with this:

1)What transmission fluid should be used?

2)What tramission fluid do you recommend if it is after market?(my car is still under warrenty though)

3)Does the car have a dip-stick to measure the tranmission fluid level like the oil level?

4)How much transmission fluid is needed, exactly?

5)How would I go about changing this myself if at all possible(I will do this at a friends shop with the right equipment)

6)Thank you!
