Drivetrain - 2001 - 2010
I have an 02 duramax with allison trans and recently drove about 75 freeway miles in 4high at 75-90mph.about a week later I was on the mtn and pushed the button to go to 4hi and the light flashes several times then goes back to 2wd. The same when I try 4lo. Anyone have any answers? I hope it...
