I searched around and also checked the very helpful what size is that nut and bolt for a 1g but I want to ensure i'm buying the right stuff.

2G manual transmission
- Fill plug is M16 x 1.50
- Drain plug is M18 x 1.50

The nuts and bolts guide says the fill plug is M16 x 1.50 and the drain plug is M18 x 1.50, i'm confused because autozone says the fill plug is M14 x 1.50.

Can someone confirm the right thread and pitch for each?

ASA & parts catalog show fill as M16 & drain as M18. I'm getting ready to install my tranny from a clutch job & can measure both tonight after I get home to verify.

You trust autozone?? Whats the likelyhood they are quoting a 2g non turbo? I don't even bother with them anymore. I would trust the nut and bolt guide
