A transmission leak is not something to ignore. The transmission fluid serves to cool and lubricate. With an automatic transmision, the fluid transfers power, and provides necessary pressure to the internal parts of the transmission. All of these functions are affected when the transmission fluid is leaking and is now low from that leak. As the amount of transmision fluid goes down, your transmission will start slipping which causes overheating resulting in damage to the transmission and ould ultimately require a major repair to enable the transmission to function problem.
