I believe argoparts dot com is still up for pictures under the D15. Many sponsors on this site should be able to hook you up with the parts.

If it's the shuttle lever that kicks back to neutral then you likely only need to rebuild the wet clutch assembly. Same as the HI-LOW on any ag version tractor. If it still pulls good it may only be the cams on the follower or the tips worn off the shift yoke. Remove the side plate and look inside for worn edges. The yoke can be replaced without splitting the tractor.

I forgot you were talking about an I-40, not the I-60 which is based on a D-15. Same internal design but I'm not sure how the wet clutch is accessed.
