Thanks for all the info. This eases my mind a bit to find this is a common issue and it is not transmission failure.

Not a good selling issue, but if that is all it is, I can live with it. Just seems kind of crazy that GM can't get this ironed out. I was reading they had the newer ones straightened out but if your 2023 is doing it as well, I guess not. Thanks for info.

Just wondering if yours did this since it was new? Or did it start after more miles where put on the truck? I will check fluid color and smell, probably just go a head and change fluid it does have 45k on it. I have no record showing it being changed. If this is a regular occurrence, its's very strange that it only does it on the first shift sequence. If I would have felt that when I test drove it I would have parked it back in there lot. Just hoping I didn't buy myself a nightmare. Thanks for your response's

Hello I am new member to the sight and I was looking for some advice to this issue. Recently purchased a 2020 Silverado 4x4 45,000 miles 5.3 motor with 8 speed transmission. Never noticed when I test drove it but when I first take off after it sitting all night, transmission like slips or hard shifts between first and second gear. Only on the first take off. The next take off it is fine, but it does it every time I take off after it sits all night. Anyone experience this issue? I read some things about fluid change. Not sure about this but seems more like possibly electrical or software issue. I let it warm up first and it makes no difference. Heck I had a 2000 Silverado for 20 years 200k miles and I don't think transmission fluid was ever change. Never an issue. A little nervous because warranty has expired and not sure if this is covered under powertrain warranty. Thanks for any help on this issue.
