Truck is a 2014 Silverado, 5.3, 6l80 , 4x4. 12500 miles
So my problem is, randomly, usually after i drive it for a while then make a quick stop ( shut the truck off for a few minutes) The transmission neutrals between the 2nd and 3rd gear shift at about 30 percent throttle. The engine usually revs about 1000 to 1500 rpm, then catches 3rd.

I took it to the dealership and they "can't duplicate the complaint" and says all is normal.

Any Ideas?

 

Gear selector switch on side of transmission has a slight adjustment.. Have you messed with this any?

 

Not at all, you think it clould be the culprit?

 

Most likely not if you or anybody else has not messed with it. They just dont go out of adjustment by themselves but I would put my hands on it to make sure its not loose for some reason. If it has moved any would will see the wear in marks next to the bolts.
