There's tons of posts on transaxle oil for the hydrostatic 2K series machines. I'm not sure when CC made the switch-over to the expensive "Cub Cadet Drive System Fluid Plus" for the 2K series, but I'm thinking it was about 3yrs ago. Like bermuda_ken says, the red stuff was never spec'd for the 2000 series. Even at $8/qt you almost never need to change the stuff. They hold ~6qts and the stuff looks as clear as cooking oil with hundreds of hours on it. I use the WIX equivelant of the CC hydraulic filter, but it looks just like a white version of the CC filter. Like you'll see hashed out in many other posts on this topic, I bet these transaxles would do fine with a synthetic 15w-40 or 20w-50, but why risk the warranty?
