There's no seal on the input shaft, but there is a gasket on the retainer that the throwout bearing rides on. Also, there's no gasket where the countershaft goes thru the front of the tranny case, but some sealant around the depression in the bell housing for that shaft can take care of potential leakage there.The countershaft also is exposed at the rear of the case, and may seep there if it's not real tight, but again, a little sealant can deal with that.

There's an exploded view in the service manual.
