I mean, some of the embedded stuff is iffy too. I mostly agree though. For example, the Active Fuel Management in GM V8s requires the TCC to slip around 10-15 R

I mean, some of the embedded stuff is iffy too. I mostly agree though. For example, the Active Fuel Management in GM V8s requires the TCC to slip around 10-15 RPM all the time, so that if it goes into 4 cylinder mode the vibrations won't transfer through the drive train. Not a recipe for a long transmission life.
