Transmission will not shift out of 1st gear. Took to shop had been told speed solenoid, replaced both, flushed tranny & changed oil. Only to find out that need a new transmission. This truck has been nothing but trouble from the minute we took the plastic of the seats. Brakes, bearings fuel lines, springs water pump etc you name it have receipts for all of it. Under warranty & after. This truck is a lemon. GMC will do nothing, dealer just puts head down & walks away because he knows major issues in the first 90 days of owning & continues to this day. This pickup has never left the blacktop. No offroading, not hunting or anything else, no vacations in fear of being stranded. Junk junk junk & now I get to try to figure out what to do when christmas is 10 days away. I don't think my children want a new chevy vehicle ever.
