Jags, check out the Deere 4410 with the ePowrReverser. It's a true shuttle shift with a wet clutch instead of the converter. All the fun and none of the heat! Not sure if the newer 3x20/4x20 machines with the ePowrReverser trans have the same design.
Oh, I can only imagine what is coming out of the newer machines. Things do tend to get better with time. A wet clutch could be just the ticket. So with the wet clutch is it still a gear drive (positive connection) with none of the converter slip? I am guessing so. That would be pretty cool.
