Good video. Motorcraft GL4 saves the day! Technical product info on Redline's GL4 is very direct about how GL5 is reactive with synchronizers and different friction. Do what this guy did!
Excellent Video; however, I had trouble finding info on Automatic Transmission fluid changes (especially for 2006-2009 Miata NCs). On the Manual Trans. there are Fill and Drain bolt (top-Bottom 23mm and 24mm) BUT on an Automatic Transmission there is a 24mm Top fill bolt (on the side) and a regular Transmission Pan drain plug "under" the transmission with a 9/16 bolt. Also the Side Top Fill bolt has a "rubber" washer gasket (NOT a crush washer) so just snug it to keep it drain coming out (wouldn't torque it hard). My 2007 Car Manual calls for JWS-3309 Trans fluid and I found three types on EBAY/Amazon...Mazda Fluid, Aisin ATF-OT4 and Idemitsu ATF Type M. Also the Automatic Transmission takes three and 1/2 quarts to fill. The rear Differential has two bolts 23mm fill and 24mm drain (both with crush washers and torqued to 25-33 ft lbs). I used Redline 75w90 gear oil..took less than 1 quart.
Good video. Real life, but I'm sorry to say you missed an important step. You Must Always crack the fill nut First when changing Transmission and Diff fluids. If you drain the oils and then can't fill due to a seized bolt you are in trouble. You'll need a tow to the shop.

Thanks for sharing! 👍🏼
Thanks will be using this vid
Do you want the trans/oil warm?
did you end up using the last quart of fluid or nah?
Nah bc not all of it drained out
How often would you change the trans fluid?
Probably every 40-50k miles, not often unless you’re tracking it a lot.
Hilarious!
