The ford 10R80. 10 speed transmission is famous for being terrible dispute being in use since 2018.
As for toyota their new engines and transmissions arent really any better for fuel economy but seem to have reliability issues anyway. I think its more of a problem of too much power as the HP war rages on for more powerful engines.
