I've now found the only way to fly is with the adjustable hobbs switches. You can set exactly what you want the thing to do.
The stock 47RH TC leaves some to be wanted as far as stall speed goes. They are pretty much the same as the stock chevy diesel converters, a bit too high for the cummins. An aftermarket low stall converter solves the problem and works great.
I don't run the 4-3 kickdown BS. For the trouble of getting it to work, it's far easier to just drop the shifter into third when you need a hard throttle 4-3 shift. 3-2 and 2-1 kickdown function perfectly normal, they're controlled hydraulically internally.
