Last night I had my 1618 (with dual trans.) connected to a trailer backed up to the garage so I can take a load of stuff to the dump. My driveway is sloped so the rear of the tractor was higher than the front. I noticed I had a fairly significant leak at the flange between the differential and rear transmission. I'm guessing due to the pitch, diff. fluid ran into the tube and found a way out.
Should there be a gasket in there to keep fluid in? I'm looking to learn what is involved to repair something like this.
