I have a 2019 Silverado. The truck is a 4 cylinder and I use it to pull a single axle lawn trailer. This is the third time it has happened. After using the truck or having it idle in park for a small amount of time, you push the brake down, and put the truck in drive. The truck will only let you get to about 2 mph before all the wheels lock up. I have to put it in park. Then back to drive and it will roll but as soon as you give the Truxk too much gas, the four wheels will lock up violently. The last two times, I had to leave my truck overnight before getting it to run somewhat better. It’s been to the dealership after both incidents. Anyone know of anything?

 

is the door open when this happens? If yes, they may have programming in the trans to do this. Ram trucks with dial shift ZF transmissions are programmed to do this. Check your owner manual.

if not....dealer time!
