1983 280zx tranny leaking at shifter.

Postby Dimes4Life » 12 Oct 2016 00:33

Just slapped this tranny in. It runs great but recently under load gear oil spray surges out the striking rod location. I replaced front & rear oil seals..and I'm using MT90 gear oil...also made sure the breather was clear..I've read that I might need to replace O ring in shifter cone. I purchased the o ring as well as striking rod guide seal. Wondering if there's a thread on how to replace..is the o ring within the inner rod or the outer shift pivot?...

is your trans the FS5C71A or B? Looking at my Motorsport Schmatic Catalog these two trannies are very different at the shifting mechanisims sealing. But both show an O-ring within the tail housing. All the shifter parts look like they can be removed without pulling the trans but removing that O-ring maybe a different animal and difficult at best with trans in the car unless you can get the tail housing low enough to get at everything. I've never had to do this so I could be blowing hot air.

Here is the correct advise from a guy that has done about 7 280zx transmission rebuilds. There is a seal that the shift shaft slides in you will need to replace it. You should also replace the o-ring on the shift control selector. The transmission WILL need to be removed from vehicle and seperated to do these seals no way around it.

Seal P/N 32858-U6702
O-ring P/N 32710-14600

Available from your local Nissan dealer
