I went out  today and started my 56 after sitting since Nov.Started right up after filling the carb.Let it run and warm up.When I backed it out of the garage there is a small puddle of ATF which was there before I started it.Wasnt leaking when I put it away.Rebuilt the motor last year and installed a new front pump seal as precaution before re-installing the transmission.Hoping this is just a temporary leak as a result of the long cold winter.Only about 3/4 litre of fluid.Any ideas or input?
