Repairs Snapper transaxle installation

[shadetree4640]

Have a mid 90s snapper tractor (LT120G30BB) and had to pull the transaxle to replace the upper/lower cases. Upper craked, bull gear moved and broke the lower case. Have the new cases, tranny reassembled, and ready to reinstall. Just waiting on 00 grease for the case, which was a real search on its own. Just asking if anyone has a good reference (paper, bulletin, video, etc) on installing and making sure the connections are all correct. Can likely do it from a parts reference diagram but maybe there is something better out there. Thanks much.
