When my truck is in tow/haul mode, it will intermitanly downshift to first or second gear, which causes the engine rpm to drastically raise quickly. When it does this, I have to put it back in normal mode and it goes back to normal. I also have a problem with my cruise control not working anymore. I'm wondering if this is connected in any way. Anyone have these issues with their vehicles and have any ideas on what the problems with mine could be. Thanks in advance.
