So today is the first day I have driven my 40 since rebuilding the t-case. My t-case doesn't seem to leak anymore, but now I seem to have a leak from somewhere on the drivers side of the tranny. Granted I just took a peek in the parking lot at work, and it's only a 3/4 inch round spot it left, but i'm a little aggrevated. If it's the fill plug missing a crush washer i'm going to feel pretty dumb, but is there anywhere else this could be coming from? I filled the tranny through the shifter with the fill plug out after I put the tranny and case back in. I also discovered that my rear seal seems to be leaking now. After I just put the tranny and t-case back in. Grrrr.
