By transmission, do you mean where the shaft comes through the hull, beneath the engine? If so that is called the dripless shaft seal. The tubes running to it bring seawater to the seal to cool the spinning shaft. If water drips out from the 1/2" hose that feeds the shaft seal, you have a leak there. If water drips from the point where the shaft passes through the seal you have a bad seal.
Watch this 2 minute vid and it may make things clearer.
