Alright guys, just wondering if anyone knows why my truck is doing this, or if any of y'all have experienced this, too.
I have a 2014 chevy high country 2wd l83 5.3. Truck has 133,000k on it, I've never had a problem with it using oil.
But I recently took a trip to Dallas and on the way back to my house, I notices my truck would shake every now and then. I tried to figure it out. I noticed it only did this when it went from v4 to v8.
Feels like its downshifting when it changes from v4 to v8.
But its not shifting!
Is it a bad lifter?
