Miata Transmission Cork

thingiverse

This cork is used to seal off the Miata's transmission output shaft to prevent any fluid loss when working on the car. I used the cork when I was pulling the engine and trans out and didn't want to lose any of my precious Royal Purple. Worked flawlessly! **I've used this on the 5 speed transmissions.** From what I've read the 6 speeds have the same drive shaft diameter, so it should work for those as well.
