2002 GMC C2500 V8 Four Wheel Drive Automatic 50000 miles
Allison auto drive selector
When I push this button it blinks but will not engage.
returns to 2 wheel drive or to high 4X4. Has been like this for several months. Does not appear to affect high 4X4. Is this a large or small repair. Can I cause damage if not repaired?
