My throttle control/power train light has come on

High engine speed suggests the transmission is slipping. That could be as simple as low fluid due to a leak, but regardless of the cause, that slippage is going to overheat and destroy the clutch plates very quickly. Forcing the car to move is going to turn this into an expensive transmission rebuild. More than likely the damage has already been done, but there are still other internal parts that can be damaged, which will add to the cost of the rebuild.
