Looking for possible reasons why the up/down switch on the column shifter doesn't work. I've checked the fluid and reset the tcm. It's a 2010 1500 Laramie with the 5.7. I bought it a few months ago and I haven't been able to get it to work since. I work at the top of a steep long hill, so coming down without the ability to hold low gear is not only dangerous its also causing me to wear through brakes fast. When I first bought it I had to have another part replaced because it wouldn't down shift when I hit the gas. I believe it was a valve of some kind. They called it the variable valve timing control valve. Just hoping someone on here can point me in the direction of what to diagnose as the cause. Thanks for any input
