While having the cruise operational and desending a hill, the desend control kicks in and allow the trans to downshift to 4th gear ( in my Traverse). In the past, the trans would upshift again to 6th gear, once the terrain leveled out. Now, the trans will NOT upshift again within any reasonable time, today it took several miles of rolling along in 4th gear before the trans upshifted once again ..to 6th gear.
Has anyone encountered this and what was done at dealership level to correct the issue?
I have read about the trans being "reprogrammed", but don't know what the end result was .... after the reprogramming.
Any help is appreciated.
