Does clutch and gearbox order matter?

If you were to put the clutch after the gearbox, you would likely need a far bigger clutch due to the much larger torque that it would need to transmit. Pulling away even on level ground would be ...

Car vibrating when brake pressed in idle

700R4 Lockup Torque Converter? Lockup Solenoid? How do I do it? Kit Only?
