I was using the MTD 1024 I bought at Sam's Club and she was doing fine until I tryed to kleen the snow at the end of the driveway. It stalled like to normally does under a heavy load like that only this time she will not start. It was snowing so I didn't notice but it also started leaking what looks like transmision oil all over the garage floor. Could I have burned up the transmission? I have changed the engine oil on a once or twice a year but I never changed the transfluid.
