    If my intention is full stop or to get down to 4th gear to make a turn, should I split gears? Give me good reasons to, please?

    ... does this sound like a tranmission busting driver alert or am I janking the dog's chain a bit?

    Exactly. If it is flat terrain RPM will jump higher but not out of the range. Why it would be a problem?

    Depends on speed, cornering, weight.

    Good post....might need to add what the terrain is like during and after the turn....up-hill ( steep climb or not) , down-hill ( again steep or not )...either way slow and steady is the best way....at least IMHO.

    You might want the full benefit of the jake, if not don't split.

    That is it.

    To explain to a newbie. Running down a hill I might drop a half step just to let the jake be more effective or run the engine rpm under the limiter at the speed that I want to run on the hill. That is about all the effectiveness of the 13/18 in downshifting.

    Running on the jake down the gears to get in low range or come to a stop by splitting is much less effective then taking whole gears. It is much more time consuming, more effort, and less actual (jake, compression) braking. Of course you may have to take one half step to get into low range just because the range shifter does not move unless you are in the lower half of the gear.
