    It's too heavy and viscous, it won't lubricate the bearings properly. Use ATF.

    Nah you'll be alright. Just dump that gear oil out and run what it's supposed to have in it.

    Yup, get that gear oil out and throw some ATF in, you should not have done any damage to it in that short of time.
