I have a stage 3 twisted diesel transmission. It has about 25k miles on it. About 5k miles ago I broke the over drive planetary. Sent it back and had it fixed. A few weeks ago and then again today, I see a leak under the truck and its transmission fluid. Seems like it's coming from up top around the breather as best I can tell. It's not overheating, not beating on it. Just driving home from work. Never had this problem until just recently. It's not overfilled, or if it is, it's not by much and it's been overfill for 5k miles and it just started coming out now. Any ideas?
