Update on the the hesitation and shuddering (Official Chevy name chuggling).
It returned with a vengeance about three weeks after the EMC update. As i drive into the city daily, the stop and go traffic is so frustrating it makes one mad.
One would think technology would make things better - not worse.
Long story short, i took it to another dealer and had the same tests performed. Imagine this - they could not produce the problem.. but gave me a nice Chevy Tech bulletin stating the truck was designed to do this.
I opened a complaint with the Chevy Exec Offices that is ongoing.
Added to the issue is the Hill Decent Control thing that operates like a Jake brake on hills. This thing is designed to operate at speeds less than 30 MPH, or when in cruise control at higher speeds (maintains downhill speed while in cruise control).
However, mine engages at highway speeds when you tap the brakes on a hill. So 70+ MPH and all of a sudden your truck RPM's go to 4500 (or higher). No brake lights and your truck is nose diving. No quick recovery either - shift to neutral or manual and shift up.
As feared, engaged during a snow storm when I was doing about 35 - loss of control of rear tires within a heartbeat (no - not out driving conditions). Went sideways and back before I could engage manual sift and regain control.
Of course, even with this, the dealership could not reproduce the condition.
Back into the shop next day off.
Exec Offices are interceding, and keeping track. Problem is, as the last shop presented me - Chevy is claiming they designed this to be like this.
So what most of us over 40 or so would classify as a real bad miss, or failure to shift condition - is the new factory PROUD norm.
If any are considering this vehicle - go on extended test drive. Ensure there are hills in the test drive at low speed and highway speeds - and tap the brakes. Also make sure you are in some sort of traffic where various speeds are encountered.
But truth be known, the hesitation and rough shift only produced after a couple hundred miles or so.
The saga continues.
Is your position a short term gain - or a long term loss? Separate the issues.
