Help! Poured the wrong fluid in my Auto Trans!!

Long story.... but i accidently poured approx 150ml of fuel injector cleaner into my auto transmission. the transmission was almost full when i did it. What was supposed to be going in was ATF fluid to prevent leaks and stop slippage. How bad is this? Any ideas if this is fatal? will the rest of the fluid delute the small amount of fuel injector cleaner? I do know, that because the car has an 81 3 speed auto in it, the car runs in the higher rpms while at speed. as a result, the ATF fluid usually needs fluid once every couple weeks. can i just let the stuff slowly leak out?

thanks

The best thing to do would be to drop the pan and drain it, and get the system flushed. I don't know how harmful the injector cleaner is, but it can't be good for the tranny.
