Give people more than 5 minutes to respond. Your thread is already the top one

You really don't have much choice.

Doubt it will "hurt it" I'd fill it up, run it for a bit and if you want re-drain/fill once more.

it will be fine, ATF has so many detergents in it that will disolve any remaining gear oil. if i were you, i would drain it, fill it with ATF, put it through a few (10) heat cycles and change it again.

As long as you didn't run it with the gear oil, it should flush out. If you ran it, the carbon friction rings will absorb the gear oil and you'll never get it out and have to replace all the friction rings.. I had a Dodge Ram SRT10 T56 that came through with that exact situation..

For reference, I found the old article that explains modern synchros VERY well.. It also talks about the problems with gear oil in modern friction rings...
