Does it do this only when the car starts moving or when you first turn on the engine?
Does the meter needle stay hard over or move at all?
Is the tachometer working OK?

If the tachometer is OK then there may be a problem with either the meter itself, the main control board or the input from the TCS.
You may have to disconnect the lead coming into the gauge assembly (A15) to determine where the problem is, whether it is internal to the gauge assembly or not.
