I have a 2000 Silverado 2500 6.0 that is having some hesitation/cutting out on acceleration. It’s weird it seems like if you ease into the throttle it doesn’t cut out but if you mash on the gas it acts like it wants to die. It does it in park and in drive. First noticed it when I was pulling my boat out of the lake and I could barely make it up the boat ramp, it was spitting in sputtering until it eventually seems like it cleared up and started going normal. I replaced the spark plugs, spark plug wires, fuel pump, fuel filter, ran seafoam through the gas, and change the air filter but it seems to not of helped there’s also no check engine light. What could be the issue, thanks!
My 2015 Silverado 1500 4x4 crew cab has about 110000 miles on it. It just started having an issue that I cannot seem to fix. The engine stays running when I turn the key to the off position and remove it. The accessories turn off normally and the RAP seems to be working. Meaning the radio and things turn off when I open the door....this truck is all stuck with the exception of a light bar. I’ve already pulled the light bar fuse at the battery hookup to see if that had anything to do with it and it made no change. Any ideas? Thanks
Ok so I have a 2015 gmc sierra 1500. after backing up and putting it into drive I get going for about 5 to 10 seconds ill get a jarring lock up for a split second. First time it happened I was going about 40 and I bounced off the steering wheel and left a little skid mark. It sounds like either my transfer case or transmission is locking up but it literally lasts for a split second then goes away. also I've noticed that after shifting from reverse I hear a loud transmission whine before it does it. This has happened at least 30 times for about a year and dealer says they can't recreate it.
It's the 6spd tranny
Also I know all about the normal GMC transmission clunk when shifting I have that too but I've learned to live with it. This is something else entirely. Its dangerous and I can't find anything on any forum mentioning this issue
