What causes transmission fluid leaks and how to fix them?

A transmission oil leak is like blood loss in a person; it has a significant impact on a car. It can cause difficulty starting, slow acceleration, slippage, and in severe cases, abnormal noises from the transmission. There are many reasons for transmission oil leaks, such as worn or deformed oil seals, worn or dented journals, damage to the housing mating surfaces, or damaged gaskets. Prompt repair and maintenance are necessary to avoid driving with a leak.
