6-speed auto tow/haul mode
When I place the tow/haul switch to tow I experience some premature and
violent downshifts. With a loaded trailer the rear tires will actually chirp when it downshifts. Has anyone else experienced this? I have just about given up on this and I use the exhaust brake instead.

Mine does the same thing, and that TSB doesnt apply to what I'm expericencing or the time frame of my truck. However I can only recall once unloaded when it downshifted hard enough to chirp the tires. I find that it does down shift hard enought to make the exhaust brake really work though. I just dont find it to be that big of a deal.
Sounds really good when it starts popping off through the stacks.
