Bought this truck last year, noticed differences in shifting compared to previous silverados I have owned, some subtle, some not so subtle.
Accelerate to 35mph, let off the gas coming up to a stop sign, the truck's remains in gear and sounds like an engine brake as approaching the stop sign. I previously recall my trucks RPMs dropping to 800-1000 when I'd let off the gas and coast, like going into neutral.
Sometimes when setting cruise to 60mph, my truck will remain at 2K+ RPM for extended period of time before finally shifting to the 1.5K range.
When towing these issues are amplified. Interstate driving at 69mph. My truck runs 2.2K rpms. If I decrease my setpoint a few mph the truck will shift into a higher gear and RPMs drop to 1.7K. Going up a hill, it jumps to 3.3K-4.5K depending on how long the hill is. Sometimes it hangs at that high rpm after i've gone over the hill and back down it for a period of time. I often try to tap the break, reduce my cruise set points, trying to get it to shift into the next gear.
I've taken the truck to 2 difference shops, and they've tried diagnosing and found nothing.
Do I just pull with it and if it blows it blows or what? lol
Has anyone else experienced this and found a solution to make it better, or is this just the nature of this POS 8 speed?
Thanks for your help.
