I watched that, but didn’t catch what the real issue was. To me, it seems like Toyota was PWM’ing the lockup to smooth things out, with the (completely expectable) result of the lockup clutch wearing out? That’s a swag on my part. Aisin transmissions tend to be long haulers.
I have noticed that my Toyota’s were always quick to unlock the TQ though. It’s like they know the clutch is weak. Maybe they don’t PWM it, and they really aren’t rated for full engine torque. All I know is, a lot of work to fix something that shouldn’t be a problem—lockup TQ’s have been around for a few decades now…
