I have a 2015 Silverado 5.3 with 114k miles. Over the last few months, there has been a hesitation, jerking when accelerating from a lower speed around 25mph. It’s fine til about 25 or so mph then starts to hesitate, jerk a little as it switches gears. If you press the gas down hard, it shifts no problem. No other issues at high speeds. The issue does not appear to happen when the tow mode is on.
Can anyone provide any insight? Transmission issue? I’m reading a lot about the Chevy shudder and vibrations. My truck does not have a vibration feeling like a rumble strips that people are describing.
also, had a DOD delete done about a year ago. The issue started about a year after the DOD delete
Any insight or help would be appreciated.
