Good point, transmission not serviceable on my lawn tractor either, gotta believe you put 300 or more hours on one it couldn't do anything but extend the life of it. I'm looking for a good siphon for my daughters El Camino, so gas and 20 gallons of it. She's not driving it and it's sludging up, she put premium in it as always but not ethanol free, her Holley doesn't like it!
