See here for Transmission Fluid Analysis by Blackstone Labs:
- • ND Miata Transmission ...
Parts / Tools Used:
- 0000-77-114-QT - Mazda Long-Life Gear Oil LS - 3 Quarts
- 9956-41-800 - Crush Washer - x2
- 24mm Crowfoot (required to remove and correctly re-torque the fill plug)
- 24mm Open Ended Wrench (optional - can remove fill plug but cannot torque it)
- 24mm Socket (recommended)
- Torque Wrench (I believe the transmission is aluminum - I highly recommend properly torquing the plugs to avoid stripping the thread)
- 12mm Socket (12mm wrench may also work but you'll have a hard time accessing two of the brace bolts)
- Ratchet (recommended)
- Fluid Pump (fits quart sized bottles or whatever size bottle your oil is packaged in)
- Drain Pan (must hold at least 2.0L)
- Impact (optional - don't use it on the transmission or to reinstall the brace fasteners; if you strip any of these threads, you're going to have a bad time)
- Oil sampling bottles (optional) (kits are free from Blackstone Laboratories, see link at the bottom of description)

Check your owner's manual for fluid change intervals - the standard transmission fluid interval is 60,000 miles or 4 years (interval may be different based on your climate, driving style). This fluid change occurred at 24,872 miles and 4 years after purchasing the car new. The transmission is filled until it starts to drip out of the fill hole, the fluid capacity is ~2.0L and Mazda sells the transmission fluid in quarts (0.946L) so you will need three bottles.
The hardest part of this process is getting the car raised up to do the work, whether that is on a lift or on jack stands. The actual process of draining and refilling the transmission is easy but tedious if you have the right tools. Watch out for the exhaust heat shield on the passenger side when removing the drain bolt.
I will post a follow-up video with an oil analysis by Blackstone Laboratories.
