There's a new fuel system cleaner from Chevron called Techron. It's supposed to be something entirely new (polyether amine (PEA)), for cleaning
deposits out. Don't know yet, I haven't tried it. But I did buy some to try.

I should point out that the better brands of gasoline do a good job of holding deposits down compared to cheap gasoline. Plus a few of the better
brands are starting to use the PEA additives. Although I suspect the main reason why is that more PEA can be added than was practical with the old PBA
additives.

BTW, I wouldn't drive with ATF in the oil. Just let it idle in the driveway for a while, and drain it. Don't stress it out while it's removing goop
from the inside of your engine. The old practice was to add a quart or two to your oil just before your oil change.
For your fuel system, both Ford and Chevy sell a "top end cleaner", that is just about the best thing around to use. It goes in the fuel line, in
place of the fuel. People hang it up like an IV bag, and idle it till it's done. It wasn't created for fuel injection.
I have no idea what ATF does to a modern fuel injected engine. I actually like carburetors...
