Help! Put oil in transfer case...

[Mark-in-CO]

I can't believe it. I thought I had grabbed the Mobil 1 Dexron III ATF but started pumping in Mobil 1 oil instead. I realized that the fluid in the pump tube was gold, not red, after maybe 2 or 3 ounces went in.

The transfer case is a Borg-Warner full-time unit in a 1995 GMC Safari. The drain plug doesn't quite let all the fluid drain, so I have been purging by dillution effect using some cheap ATF.

How perfect do I need to assure that there is no residual motor oil?

I would only fill and drain once with ATF...transfer cases aren't too picky.

Thanks, I figured that the mistake was either tragic or minor, hopefully the latter...

ZmOZ nailed it. Probably not worth the time in flushing you already have into it

consider it a very clean transfer case. (Heck a little motor in the ATF may have helped protect the gears!!!)

Thanks for the confirmation! You're right, I do have the cleanest transfer case in town. I am always amazed how easy it is to have a brain-**** .
