Glad to see that I'm not the only one that has made that mistake. Mine was a rookie error though and I corrected it by calling Freightliner help first and then was referred to the Allison helpline, where a tech talked me thru the drain process.

Oh wait, I missed the part about the fact that there is another plug higher up that you can open to allow it to drain faster. No fuss, no muss and no big bill. Just a bit of egg on my face.
After this little mess and with the fluid level right at zero I went back and checked the dipstick....now it says low. Now wonder Allison doesn't recommend using a dipstick and calls it "for reference only".
In thinking about it, that does make some sense. I suspect the dipstick assy is put on as an afterthought by the chassis manufacturer since Allison wouldn't know where it's going to routed.
