I have a 06 chevy trailblazer LS 2wd V6, so when you are driving it when it goes to shift from 2nd to 3rd it acts like it wants to go into 3rd but sounds/acts like its in neutral instead, going to attach what codes it is throwing, I have already replaced the 1-2 shift solenoid, 2-3 shift solenoid, and 3-2 control solenoid, and Trans fluid has been changed since, full and nothing in old fluid, and new filter. have replaced the throttle position sensor & pedal now, and it will go into 3rd after you rev it up then let off the pedal its the only gear it does this in...and it isn't throwing any codes now

RepairPal Certified shops can diagnose and repair your 2006 Chevrolet Trailblazer. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Hello, not much more you can "try" - it sounds like a likely internal mechanical issue with the transmission, and further it sounds like all the other repair attempts were futile and a waste of money attempting. Spending some money on a skilled technician to help diagnose the concern is as matter choice.
