I have a 2016 Silverado 5.3L 6 spd and when I plug in my InTune it says the TCM needs an update. I hooked the tuner to the computer and let it do the latest updates last week. The tuner was on my '08 5.3L 4 spd and it worked fine. I restored the stock tune to the '08 before trying the '16. I let the tuner create a backup of the factory TCM tune and I'll post it here when I have a chance to hook it to my computer. Posting this on my phone.

Am I doing something wrong or are there issues with the 2016 6spd? I know that the 8 spd can't be tuned yet but I assumed the 6 spd was good.

Thanks in advance.

post up that backup file for the TCM and we'll get it added to the next update.

Thanks

Here is the file. Thanks

Thank you Mike. Any idea when the update will be ready? I'm anxious to tune my truck and see if the drivability improves. This truck drives like crap compared to my '08 Silverado.
