What might be the cause of a shimmy that originates at normal speeds? on 2005 Kia Amanti

What might be the cause of a shimmy that originates at normal speeds? It appears to be a transmission or acceleration problem. I do not think it is a timing belt issue as I just replaced this 200 miles ago. It lasts for approximately 1-3 seconds and then goes away and runs fine.

It sounds like a torque convertor clutch lock-up problem resulting in a shudder felt in the powertrain when it's commanded to lock up. This is not an uncommon problem and a Kia or Mitsubishi technician could be able to diagnose it. A transmission shop would be able to diagnose it too.
