My 2017 Silverado 1500 with E-assist is doing the same hard shifting from 1-2 and 2-1. It also does this thing from Auto-Stop where it will come back on at 2000rpms and wants to lunge forward.

I took it to a Chevy Service location to get checked and they told me it’s how the transmissions run. We went for a test drive and since they “can’t replicate” the problem they said there isn’t much they can do. I’m the second owner and come to find out the first owner took it in for the same issues along with shaking at 60-70 mph. They did a software update at that time, this time they said they could only run a “Fast Learn” on the transmission (fast learn is when they adjust the parameters of the transmission). They mentioned that “fix” would only help smooth it out for about 300 – 500 miles.

I haven’t driven my truck more than 140ish miles when a NEW issue happened.

I was on a hill, nose down, put the truck into REVERSE and clunked loudly. When I let off the brake and pressed the gas it went FORWARD!! Slammed on the breaks and they were HARD. Not the normal brakes. I tried again and same thing. I put it into DRIVE with another loud clunk. I started moving down the hill I realized I had NO power steering or momentum from the gas pedal. It was scary! I was stuck in the middle of a street on a damn hill! Once getting to a safe location, I turned the truck off for a few minutes. When turning it back on, it went into gear but there was no power like a V8, more like a four-banger. I drove home and parked it.

I called service to update them on the issue and found out they received a new service bulletin regarding the brakes being hard to the touch as I explained to them.

This truck is beautiful but NOT worth the headaches. I’m only at 43,xxx miles and I have excellent extended warranty.
not putting anymore miles on this thing.
