I need help guys. I bought a 2001 ls miata 6 speed a couple months ago and wanted to change the transmission fluid but wasnt 100 percent on the location of the fill and drain plug. i did a search here and the google but found nothing that would help me. does anyone have a "how to" or photos of the under car for a NB? the only thing i could find was on youtube by miata fan on a NA. any help will be appricated, thanks.

Drain plug should be pretty obvious. It's a 24mm right on the bottom. Filler plug is on the driver side of the trans. Use an open ended wrench for it (can't recall size) Takes 1.8-2 and some change qts. Make sure to use a new crush washer on the 24mm drain plug.

Take out the fill plug before you take out the drain plug... If you cant get the fill plug out, you'll have to drive it to a shop. and you can do that if you've already drained the fluids.

(Edit: Reason you may not be able to get the fill plug out is to some gorilla at Bob's Mufflers and Oil Change's tightening it 1 million psi)

Also, do the rear diff and trans turret fluid at the same time. GL brotha

I think it's a 22mm but eh.. i might be wrong.

Completely off-topic side note: My SRT4's directions for filling the trans were to pour the fluid in until it came out of the fill hole and overflowed on the trans, then you plopped some flimsy rubber cap on it and you're done. The cap looked like a milk jug cap. That car was a hoot..

I meant for the filler, the one you couldnt remember the size. I recall having 2 wrenches under there... This could also be becasue i had a plug replaced though.

Does it block you out when the engine is cold or warm?

Relatively common. I usually go 3rd to R.

Use a quality metric adjustable wrench... ;)

On my 2002 both drain and fill plugs are 24 mm.
While it's a good practice to make sure you can open the fill plug before you drain the fluid to make sure you can fill it back up, the NB trans has an "emergency filler" - through the shifter turret.

My six speed sometimes is difficult to get reverse. I also go into third then reverse. It's been like that since I had it at 26k miles. No matter what fluid has been in the transmission it's still the same. You get used to it.
