Nah don't.
Few things:
1. Do you know your injectors are actually dirty? Like, I'm not being a smartass. I've had my intake apart at ~120k and the deposits I had were clustered on the intake valve as a result of PCV recirc. But the injectors themselves were spotless. When I installed a PCV catch can and had my intake off again later, there were clean spots where the injector fuel spray contacted the intake valves. Once I removed the source of the buildup, the included detergents in the fuel did a great job of cleaning stuff up on its own. I also only use quality fuel - shell or chevron when available, and will avoid cheap shit from arco / costco at all costs. Yes I know arco has some certifications to it. My decision is based from anecdotal experience (noted most customer fuel pump failures were using arco) and an aversion to business practice (**** BP)
2. ATF isn't a solvent. Hell... It doesn't even have detergents in it. Same reason it's not advised to put in engine oil as a cleaner. There's no combustion taking place in a transmission, therefore detergents aren't added. It is, however, heavy in dispersants to keep clutch material shed in suspension.
3. Concentration is proportional to cleaning properties. ATF in the tank at some 1:100 dilution ratio won't do shit.
4. I'd worry about it affecting the catalytic converters. The cats will tolerate some oil from the PCV system. But I'm not sure about that much
5. YMMV, but when I was around 150k or so, I did a test where I added some techron injector cleaner to my tank. Controlled variables pretty well, noted no difference. Didn't feel like pulling my intake apart to really check gunk and junk and measure, so my takeaway was either that it did nothing or I had no deficits in my injectors / intake.
6. Honestly, if you want to clean your injectors, either get a pressurized bottle that puts pure cleaner through the injectors under pressure, or find a shop that does it. Or a service that removes the injectors from the vehicle and cleans them in an ultrasonic hot tank. It's been my experience those are the only methods that work well, with removal and manual cleaning being the best approach as cleaners can be tailored to remove anything there instead of being safely combustible.
