Some common places to have transmission fluid leakage are at the speed sensor mounting point, transmission drain hole, selector shaft, radiator, filler tube base or even due to a clogged transmission filter.
Your may even notice that with a delayed drive or reverse that your vehicle suddenly jumps out of gear while moving.
