Hi, there,

Last night my fiance decided to be very nice and change the oil in my 2004 Subaru Forester. After accidentally draining the transmission instead of the oil pan, he then proceeded to refill the transmission...except it was actually the front differential.

We needed a large torx wrench to get the differential plug out to drain it, but of course there was no such tool to be had. And this was yesterday, a federal holiday, and after 5:00 pm to boot.

He consulted with some mechanics from his job by phone and was told that nothing bad would happen...the differential needs to be lubricated, and it was lubricated, just with four quarts too many of the wrong fluid.

It's driving fine, and he's happy to go buy the correct torx wrench so he can fix his mistake. However, he won't be able to get to it until tomorrow night at the earliest, but more likely this weekend.

Is this mistake likely to do damage to my car? Can we wait until this weekend to correct the problem, or am I better off taking it somewhere to have the differential drained and refilled?

Thanks for any info you may have...
