This speedkar99 channel definitely has impressed me (and it was done with a tooth brush?). Should mention problematic cylinder deactivation on the 2.5L NA Mazda added since 2018 MY. It’s a complicate system with a couple of major problems, cracked cylinder head and failing switchable hydraulic lash adjusters, started showing up with higher mileage however they’re rare.
I believe most DIY members in this forum know there’s a dipstick on transmission and it’s been discussed many times here. Keep in mind it isn’t like a dipstick for any other liquids checking the level, you still need some capable OBDII scanner monitoring the ATF temperature in order to check the correct ATF level with the dipstick.
