'93 FD OEM Shifter Rebuild
#27
Which parts go inside the stock transmission housing/turret/whatever? Sorry to be thick, but reading the walkthrough I'm not sure I followed the process for what was changed in there.
I ordered the boots and a new shift lever (with new bushings, etc, already installed on it) from Mazda when I took out my short shifter. But I never changed anything in the transmission and (as a result?) I've still got some slop.

81-95 Rx7 Shifter Bushing Kit (ARE80)
Don't know about bronze, but there are aluminum versions. Regardless of what the ad says, it's hard to imagine they remove "slop". And metal will wear too if not greased properly. Seems like they'd just be less likely to break with repeated hard shifting...

OEM vs Pettit Bushing
Hello gentleman , I'm reviving this thread because while doing this little project I notice something that I need an explination
I bought Petit rebuild kit & the OEM one to compare
The problem is on the OEM part #R503-17-481
As you can see in the picture (OEM on left / Petit on Right)
The upper bushing has a way bigger groove that the one the right.
Which makes me believe that it's not holding the shifter tight like the Pettit one.
Another difference is that the OEM one is made of plastic compared to polyurethane.
Also the Pettit one uses the same top and bottom spring washer and bushing. , not sure if it male a difference or not,
but on the OEM there is defintltly a size difference (the top one is ticker).
I think I will go with the Pettit over OEM on this maintenance task.

The bushings you have on the left there don't seem to be the right set to me. The one on the right seems to be taller than the ones on the left, so perhaps they are designed to be used without the spring washer that comes on the OEM ones?

I think the paper gasket typically comes stuck to the bottom of the inner shift boot (the one that bolts on with 3 bolts to the trans). You don't have to buy it separately.

I looked back in the pictures in this thread and you can see the gasket stuck to the bottom of that boot. I'm 99% sure you are good on that.
Also, I think I mentioned elsewhere in the thread that there is a Miata version of the inner 3-bolt shift boot that is bolt-in and like 1/3rd the price of the FD part. Works perfectly.

It’s a relatively low temp, low load environment in the shifter reservoir. Can’t imagine that gear oil would really ever need changing. I think the only time I’ve drained mine is while the transmission was dropped. Way less risk. Just be sure to grease per the FSM before re-submersing the shifter assembly.

I have a kit with the most commonly needed parts to rebuild the stock shifter if someone doesn't want to deal with piecing it all together. I can get the boots as well if needed. https://www.irperformance.com/produc...g-rebuild-kit/

Good fresh shifter bushings feel SO GOOD.

Your list looks complete. Just have some rags handy when you remove old one to not drop fluid
(OT - I think you know my Supra bothers out your way. Dave & Chris Black/Red MK4's. I'm in Queens)

I used a syringe with some thin tubing to suck up some of the worn out fluid. I measured what came out and poured that back in with fresh set.

And I don't really know any MK4 Supra owners...
