Re: trans leak

Re: trans leak

Muncie has no front seal.Overfill or parked on a slope will show a leak
Who knows why no provisions for a seal ...transmissions from the 40s had a seal, even it was made out of leather..

Thats where the vent is, as to why oil is coming out it could be a number of things such as the ones suggested or improper building, case stretch, oil quality, etc. Whats the age of the oil and type (some oil is starting to suck these days)? Condition of the trans? How hard do you run it? All in all it's probably not worth it to worry about it unless you are drag racing, just keep an eye on it.
