5th in the 6 speed (not 4th) and 6th in the 8 speed both have the low torque limits, and both are the 1:1 drives... Perhaps transferring torque through fewer gear sets = lower mechanical limits? Any mechanical engineers care to chime in?
Great link Estoril. Very interesting even though much of it was over my head.

As much as a tried to find some common mode of operation between gears 3 & 6, I could not. Perhaps they have torque limitations for different reasons.

I think it's safe to say, this automatic is much more complicated than I realized. So thank you again for the link!
