I see you are from Ontario may I ask were you got the gl4 trans gear oil.

I think my question has been answered, since I would have to wait to drop the old one to rebuild it anyway. Now I just have to weigh if it's worth replacing the bearings and seals, or just do a gasket kit. | | | | | Joined: Sep 2010 Posts: 2,306 'Bolter | | 'Bolter Joined: Sep 2010 Posts: 2,306 | Ok will have to wait til border opens up .You can take the top off theses transmissions and see most of the inside to check out there condition | | | | | Joined: Jan 2016 Posts: 709 'Bolter | | 'Bolter Joined: Jan 2016 Posts: 709 | Hopefully I can find a thread on how to assess one of these, once I have it open. | | | | | Joined: Feb 2019 Posts: 4,471 AD Addict & Tinkerer | | AD Addict & Tinkerer Joined: Feb 2019 Posts: 4,471 | There are several YouTube videos that show various stages of disassembly/inspection/reassembly. Some are rather long so I didn’t watch them thru. You may find what your looking for. Do a search on “SM420’ and it will bring up several. Good luck!
