yes it does have the auto button on the dash. when the electric shift motor went out it blew the fuse and locked in 4 lo. i change the shift assemby then the 4hi light has just been blinking and i am in 4hi. the front axle is working properly. If I unplug the tccm I am in 2hi of course with no lights on the buttons. thought the tccm was bad but new didn't change anything. Got to take it in this week to have the codes checked.
