I have a mazda 6 2011 that is having issues. First reverse was difficult to get in. Once I got in reverse I couldn't let off the clutch all the way or it would jump and the engine would die. No other problems until reverse went all the way out. It wouldn't stay in reverse. Next it was difficult to put in gear. Once in gear the power was nearly gone. With that the loud whining noise as I accelerated. Engine was leaking some type of fluid. Looked like oil but wasn't sure. It was around the shifting linkage. When in neutral I could hear something spinning. Got a feeling I have a tranny problem issue. Hopefully it's not. Also, I was moving it the other day and going bout 5mph and all of a sudden it stopped on a dime. Someone tell me it something other than a tranny problem. Thanks
