Well, I have been putting up with a leak in my tranny for the last 3 years. It only leaks while going down the road, it never has gotten any worse or better for that matter. I don't think that the case is cracked since it has stayed the same since I first noticed it. I was wondering if it could be the seal on the output shaft going to the transfur case? I was thinking that it might be leaking into the gap and then blowing out between the two when under power. Right now I am looking at ideas on what it might be and then later when it warms up I'll tear into it when I can have it down for a while if I have to chase parts.
