BMW makes M5 transmissions.
The Mazda5 minivan's transmission most likely uses a Jatco, since it was designed by Ford and is used across their entire line (Land Rover, Jaguar, etc.)
Toyota's Aisin trannys are designed, made and licensed by Chevy. Honda makes their own with mixed results.
Kinda weird that you think they suck, I don't know if I've ever heard anyone complain about the transmission in their Mazda.
Sounds like Google and you've got it figured out then. I was just repeating what I learned from browsing this site.
I wonder how many Mazdas the guy in the video has owned. Checking out his videos, it looks like he's getting sued by more than one car manufacturer? "Breaking News: Chrysler screws up!" "Braking News: Mercedes will destroy Tesla!" Breaking News: Land Rover screws up!"
s*** seems a little click-baity.
