For some reason a parts diagram of your model is not coming up but I can tell you that you should have a service manual to do the repair. It is not difficult but it does take some time and you need to remove the drum. GE does not provide internet access for the tech materials but contact them and they may provide the info to you since you are an owner, but if not see if you an get one on the internet. You may have to pay a small fee but it is well worth it.

You should also be aware that often in the case of this type of leak water will enter the transmission and ultimately ruin it, so before you repair the machine you may want to consider replacing it. Just saying, good luck.
