ATF Change - tools required? Air getting into the system?

[kev510]

Hello,

I'll be doing an ATF drain & fill on my M35X today. I couldn't find this information anywhere on Google and the Infiniti service manual -

What size is the socket needed to unbolt the drain plug + fill plug on the transmission case? How about on the transfer case? Differential is 10mm hex key, correct?

Also, is it ok for the air to enter the transmission cooler hose?

Thank you for your help!
