  • Transmission identifiers.

    For the past few years my transmission has been making odd noises. It was especially noticeable when idling in neutral when the clutch was engaged. On the Calabogie tour it started howling in third gear, and making unpleasant noises in all but 4th. Today I pulled the drain plug, followed by the whole transmission, since pieces of bearing race a nd lots of filings came out.
    I had this transmission rebuilt in 2008, and it's always been full of fluid and not abused. It's done about 100,000 km, but I don't think it should have failed.
    My immediate problem is to identify it so I get the correct parts. I copied this from another forum.

    " Two muffler hanging tangs + short shifter mount ears = 77-78 280z

    One muffler hanging tang + short shifter mount ears (~1" tall) = 79-81 280zx

    One muffler hanging tang + long shifter mount ears (~2" tall) = 82-83 280zx - the one we all crave."

    The shifter mount ears measure 1-1/2", so I think it's the last one.

    I havent opened it up yet, but maybe the parts I need are the same for all, or easily identified from the pictures on Rock Auto.

    I'll post pictures of the guts

    Exactly as I suspected. The counter shaft bearings are shot. I'm tempted to just replace these two bearings and not dissasemble any more. I can take them to a bearing supply and have them matched up. Or measure them and get them from Amazon for a couple of dollars each.
    I suspect the transmission shop that rebuilt it 10 years ago never replaced them. This transmission was full of water when I bought it, so that may account for the putting on the bearing race.

      Do not buy cheap bearings from amazon. If possible spend the money and see if you can get those bearing sizes from a top quality manufacturer. Cheap bearings today do not last at all. There is a video on you-tube comparing cheap bearings and quality bearings, if i find the thread i will post it here.

          Eric , you have a ZX transmission with a lockout 5th gear 82-83.
          Get bearings from a place like Canadian Bearing =Timken if you can.
          Doug Mitchell may have the numbers? he's rebuilt a few.
          You'll want new nuts as well

            Mike, at Whitehead, fixed me up with original Nachi bearings yesterday, thanks. I unstaked the one nut I had to to get at the countershaft bearings. It came off really easy with no damage at all, so I'm going to re use it.
            Yes, I saw the reverse lockout dog in there. What was that used for?
