One of the leading causes of transmission leaks is a cracked crankcase seal. If the gasket is worn, it must be replaced as the fluid inside continues to leak. This reason is easy to solve. All you have to do is buy a new (relatively cheap) stamp.
Why's my transmisson slipping?
Low gear oil is probably the leading cause of transmission slippage and is also the easiest to repair. When the fluid level drops, the pressure required to properly engage the gears decreases. This increases tension during shifting, causing slippage and overheating of the transmission oil.
