1989 ns8b water in gear oil. When I drained the gear drive there was some water in it so I pulled and drained it . I was doing a pressure check and found a leak on the shift rod bushing. I removed it the bushing has a o ring in it and one on the bottom. Changed them both with mm o rings but still leaked around the shaft. Ordered new o rings and bushing. Don’t think it’s going to fix the problem because of design. Any work arounds would be appreciated
