hello i have a 2004.5 duramax with 153,000 miles and my trasmission is starting to act up. When taking off at medium throttle the trans shifts form 3rd back to 2nd then back to 3rd rapidly. Also when taking off in full throttle the tranny shifts all around back and forth thru gears and acts like it is in neutural. I don't know whats going on. thanks

i did a couple of days ago when i did my engine oil change. I also had the tranny oil done by a local chevrolet dealer a couple of months ago. Is there a computer that the tranny is ran off of and would that have anything to do with the problem? thanks
Yes but I doubt it has anything to do with it unless you are someone has changed the calibration.
Make sure there are no codes present. Just because the SES light isn't illuminated does not mean that it might have a code. Best to check nonetheless
