Trans shifting hard

[Robbins14]

Hi, my 07 silverado 1500 With the 4l60E shifts hard after being run for a few minutes. I shut it down to get gas or to just let it sit. It will shift fine for another few minutes. It's throwing code p0700 and p2763. Not sure where to start. Thanks

At this point, i'd find a good reputable tranny shop and run it by there to see what they think. Hopefully it is just something simple but kinda sounds like your Tranny has gone south. A good tranny shop will be able to tell ya. Have you owned the truck since new? Has it been serviced like it should? That is very critical to longevity of these transmissions. I'm a firm believer in 30,000 mile service and despite what some of the yahoos on here say, I am also a firm believer in tranny flushes.

No I'm the second owner. The first owner had the TC replaced along with clutch updates with a flush At 80 thousand miles.
