Assuming there is no lockup clutch that locks the turbine and impeller together, how does a torque converter work when it is being back driven (turbine spins faster than impeller) such as during engine braking or going down hill (wheels pushing engine)?
Wouldn’t it be less effective because the curly blade angles design of the turbine?
If the turbine is bolted directly to a differential and the torque converter is filled and sealed, by pushing the car, will there be enough torque turning over the engine?
Thanks!

The engine turns the torque converter the same way if you’re backing up or going forward. The transmission just has extra gears that let it rotate its output shaft in the reverse direction – this happens when you’ve selected reverse instead of drive.
