What ever spec fluid your owners manual says to use. Your choose on synthetic vs conventional.

Lots of guys tout GM sychromesh for T5s... Mine is full of Mobil 1 synthetic ATF.

My diff is also full of Mobil 1 gear oil (I can't recall the weight off the top of my head 90w140?)... I also threw in some friction modifier just to play it safe with the LSD.
