At fifty hours, I spoke with the dealer and was told I'd save a lot of money going with Hy-Guard rather than the super udt-2 for the transmission oil change on my L4240-hst. I followed his advice and pretty quickly noticed difficult shifting and a bit of whine that seemed new. So, yesterday I spent the morning changing out the transmission oil and replacing it with super udt-2 even though I'm only at 135 hours and, yes, it was expensive. However, the transmission now shifts smoothly, and the whine is gone. Also, although I had done the fifty hour maintenance, including the filter replacement prior to this, when I took the suction side filter off, the magnet was covered with metal - some looked like machining chips, but some looked more like what I'd expect from wear. I know this has been much discussed, and I figure my dealer was trying to be helpful, but I'll be using super udt-2 from here on.
