Two other things you can try:

1. Manually downshift to 4. Tow/haul and brake jabbing work in 4, but not in 2.

2. Set cruise at a relatively low speed (40ish). With tow/haul in D it sometimes works fine.

The V10 will go up to about 4,200. It is happy there.

The trans control is adaptive. It will improve after a few downgrades.

Works fine for me on many mountain passes I need to traverse to go anywhere...pulling Cherokee behind Georgetown 30x3 I load to full 18K.

From manual:
“ Automatic Transmission AdaptiveLearningThis feature may increase durability andprovide consistent shift feel over the lifeof your vehicle. A new vehicle ortransmission may have firm shifts, softshifts or both. This operation is considerednormal and will not affect function ordurability of the transmission. Over time,the adaptive learning process will fullyupdate transmission operation.Forced Downshifts•Allowed in drive (D) with the tow/haulfeature on or off.•Press the accelerator pedal to the floor.•Allows transmission to select anappropriate gear.” (PS: I don’t find pressing accelerator causes downshift. But jabbing brake does.)
