What Owners Say
"a couple times, the tranmission shifted prematurely. i change tranmission fluid in truck, and have'nt had a problem since."
Anonymous A., WI (2019 GMC Sierra 1500 SLT 5.3-L V8)"After about 19,000 miles started experiencing shifting problems and rear end knocking when shifting down"
Anonymous, MS (2019 GMC Sierra 1500 SLT 5.3-L V8)"This problem has been occurring quite frequently lately. My truck will make a loud noise and lurch physically forward when I speed up. Keep in mind, I'm going a regular speed from 10-20mph. I am not going 70mph when this occurs. It's actually startling when it happens because the truck physically lurches forward and sounds like it's trying to get into the next gear. The dealership has not been able to help with this issue."
Anonymous, MO (2019 GMC Sierra 1500 SLE)"I have had problems with this transmission since the day I bought the vehicle. They have done a couple repairs to it, but nothing took care of it. It is only getting worse and worse and soon I will have to have the transmission replaced or rebuilt."
Anonymous A., MI (2019 GMC Sierra 1500 SLT 5.3-L V8)"When I took the truck to the dealer for a fluid change which only they can do as it is a sealed system, they said the trans cooling hoses were leaking. This cost over $1500 to replace as the entire front of the truck had to come off. The dealer said they only last a couple of years so expect to replace again soon."

"Sierra Shutter is a known problem with the 8 speed transmission. General Motors has a fix for the problem. But refuse to do a recall. Owners have to pay for the fix. Its basically a better transmission fluid and filter replacement. @ $300.00"
