Early September 2018 build, 2019 2wd 8 speed 5.3L, transmission temp never exceeded 170, now while driving same route and conditions the trans temp is 185 and the 1-2 + 2-3 light throttle shifts are slide/ bump affairs and the corresponding downshifts are very harsh. Started all of a sudden. Very repeatable. When the trans temp is below 175, it upshifts and downshifts fine. Warranty still in effect, fluid never updated to the newer Mobil 1 version. Anyone have any experience similar to this? Thanks for any insight.
I drove a 2004 Chevy 2500 4X4 for 15 years, so I have no experience with the newer models. I recently bought a 2018 Silverado 1500 High Country, and I hate the driveability of it, so I'm wondering if this is just how Chevy trucks are now? I don't want to personalize this truck that I don't even like driving due to the jerkiness. Here's what it is doing, feel free to comment on any of the "issues". I've read up some on the 8 speed transmission issues, but need to know if it is even worth fighting with the service Dept. I've only got 11K miles. Slow take-offs are jerky Fast take-offs delayed - I know I can fix this one with a $200 module Coasting up to a light slows itself to the point I have to get back on the accelerator. I don't know if this is the trans downshift or going from 8 to 4 cyclinders. The brakes brake harder than I am on the pedal. I don't know if this is the "intelligent" brake assist, but I'm barely on the brakes approaching a light and it brakes hard enough to throw me forward. or is this downshift or change in # of cylinders. It just annoys me that you can't have a smooth ride with this truck no matter how hard I try. Any help or comments would be helpful. I've got to decide to keep this truck if things are fixable, or get rid of it for something else.
Just wanted to intruduce myself and see about getting some insight on issues I'm having with a 2015 GM Sierra with a 6.2 Liter 8 speed transmission. I've been having issues with my truck since day one and looking for some suggestions on working with GM and there customer service. Without getting into details here on the introduction page I was hoping someone could tell me which forum would be correct for posting complaint and issues in pertaining to GM and there customer service. To make a long story short my truck is 126 days old and its been in the shop 43 of those days and transmission has been out twice and replaced once. Is this normal? GM seems to think so.....
