From a Motorweek episode about the 2023 GR Corolla, after describing the 3 cylinder engine (unlike vintage Saabs and a friend's Subaru Justy) the story goes on to say 'And it gets even better, with a standard rev-matching iMT 6-speed manual transmission similar to the GR Supra’s, and GR-FOUR all-wheel-drive.'

Hopefully, the components in your transmission won't have been chrome plated.

Sadly, they don't mention aspects like gear ratios, torque capacities (often different for each gear range), etc.
