What application?
Stick with it. I don't see any reason to change.

I doubt it, but call Amsoil Tech Services and see what they have to say. Ask for Kevin Dinwiddie.

You don't need to bug Kevin for something like that. He's a busy guy. If the ATF is working fine for you now, no need to switch.
ATD is fine in Dex III applications, it was designed as a direct replacement for TranSynd® Synthetic ATF. It has a slightly higher viscosity than Amsoil ATF. If I lived in Vegas, it would be my choice. One drawback is that it only comes in gallons.

Just ambient temps approaching 120° on a cool summer day.
Yes it does.

The difference is really pretty subtle. Slightly more AW/EP type additives in ATD, but both have very similar frictional properties. Neither contain ANY VI, so they are both VERY shear stable, they just use different base oil to get there.
Amsoil's published answer is interesting:

How does Torque-Drive™ compare to AMSOIL Synthetic Transmission Fluid (ATF)?
Torque-Drive™ was created to satisfy the concerns of customers currently using TranSynd®, and it carries with it the confidence to be used for the intervals established by Allison. AMSOIL ATF is a more advanced product with universal applications such as Mercon V and ATF +4. AMSOIL does not recommend draining or switching to Torque-Drive™ unless the Allison customer intends on following the extended drain interval recommendations of Allison.

I see. Based on that knowledge, and a post you made earlier about ATD being your choice in Vegas, I will give it a try. I am due for my anal retentive 6 month 40% change, and I am going to the warehouse anyways ( I love having the LV Amsoil depot within 5 min of my house, AND being close to it's manager Jim.. 
).. I typically buy 2.5 gallon bottles so ATD's lack of quart bottles does not bother me.
I also think the thicker ATD will work well in our Subaru ps units, they run very hot and cook fluid. I would like to see if the extended drain requirements ATD has will add any benefits to this application.
Thank you Pablo, have a cold one on me. ( I used your name when originally getting my PC! )

Oh really. Is it a licensed TES-295 product? Or is this yet another unsupported claim?
According to Amsoil's website, it is NOT licensed for Transynd applications. Lots of marketing spin (kinda like Fram, eh?)... no verifiable data. Not saying there's anything wrong with Torque-drive, but you're taking Amsoil's word that the stuff is ok to use in place of Transynd (Even Amsoil doesn't specifically claim that it meets the spec). The is NO independent verification.

Curious as to why you would choose ATD over ATF in an application calling for Honda Z-1?
Do you add a friction modifier additive, or use it as is?
