I filled the 'matic for the first time this weekend with trans fluid and after a few moments, fluid starting slowing dripping from the rear of the yoke. I have not installed the drive shaft yet.

Is this leak due to a dry rear seal, possibly? Oh yeah, this TH400 trans was totally rebuilt, but has been sitting in the garage for the last 3 years during my '67 restoration.

It makes me wonder what else may start leaking once I begin driving the car for the first time if this leak is a result of extended non-use.

Thanks for any opinions, Charles
