I have a 2011 case farmall 45 CVT. I have three speeds, anti-stall and reactivity, i'm not sure anti-stall is working correctly on my tractor as I can't really tell the difference. Using the FEL, the tractor can still bogg down so bad that it sticks in gear and won't go into neutral until the engine is almost stalled. This is after releasing the motion pedal. I'm going to trailer it over to a dealer this winter to have them see if there any updates. It's a **** shame the case can't look this up and tell you if it needs an update or not.
