2015 silverado transmission problems

[mainiacdave]

I have had 2 verbal arguments with PORTSMOUTH NH 03801, dealership regarding the up-shift if my truck transmission. Simply put, I was decelerating in a parking garage. I took my foot off accelerator to slow just before I drove onto a down ramp as I exited my work space.THE TRANSMISSION UP-SHIFTED AND ACCELERATED ME TOWARD ANOTHER VEHICLE. A panic stop saved an accident. Below is the last contact with Chevrolet.

Good morning Dan. Thank you for the call.

1st. I am a civilian working for the US Navy near Portsmouth Chevrolet,
Portsmouth NH 03801. I am @ work by 0600 hours. I am released from work
@ 1530 hours. It takes 1/2 hour to exit my work place and 1/2 hour to
arrive home. How will we overcome this situation. Obviously, I cannot
converse with you during those hours. May I suggest that we agree on a
specific day and you could "stay over" to discuss these unsafe issues.

Last night I spent another hour with a technician and service rep
discussing all the problems with this truck @ Portsmouth Chervolet. Ask
them for a copy of my paperwork. I brought up 3 points and added an
issue to make 4.

The noise from the engine in terrible. The ticking is heard over my
radio when my windows are down. Answer: Normal!
The transmision jerks me around specifically around 30 mph, but it
occurs at all speeds below about 40mph. Answer: Normal, the computer
does not respond correctly to the driver.
The transmisson slips after being placed in park. In my case I had
pulled the key, opened the door and I was stepping out of the truck and
it moved 6-8 inches. I was not harmed this time. Answer: Normal, we
have a bulletin about that.
The main fear is the transmission shifting up when i have taken my foot
off the accelerater. It has happened twice now. The first time I was
behind a vehicle and the truck surged forward. I had to panic stop the
truck from striking the vehicle in front.
The fourth issue I added while @ the Dealer is the clunk under my truck
when it shifts. A clunk which us similar to "rearend gear lash". Funny
that the clunk was felt this morning coming to work.

Dan I fear this transmission will push me forward into another vehicle.
I do not feel safe in this truck. Please advise. David Moulton, 2015

I have experienced all except the movement in park. All I ever got from the dealer was either "Normal" or "Cannot duplicate customer concern". I pushed as hard as I could through GM's Priority Care and got nowhere. Cannot get anyone to diagnose it and GM will not do anything because the dealer says there is nothing wrong. This truck is the worst vehicle I have ever driven and GM will not do anything about it. They no longer care about customers and are only out to make shareholders happy The problem is in the "learning" software of the transmission. It seems that some systems have problems with maybe a tolerance problem and end up shifting goofy at times, the 30mph problem is the 5th to 4th downshift. All they would have to do is add some parameters to the radio so you can turn off dynamic braking and turn down torque management and it would be fine. Since they are unwilling to work on these anymore, all I can do is learn from my mistake and no more new GM vehicles. Maybe in the future they will figure out how to make automatic transmissions again, but for now stay away. Sounds like Ford was leading the 10 speed transmission, but GM's programmers will find a way to screw it up.

Problems such as you are describing is one reason why I will not buy another GM new vehicle equipped with automatic transmission until they eliminate these issues. I have zero problems with my GM car and truck, both equipped with an old proven 4 speed GM automatic.
