2003 silverado 2500: allison..overdrive..indicator light..shift lever

Resolved Question:

2003 silverado 2500 duramax/allison. Tow/haul, overdrive overide is not working. Noticed it when the dash indicator light did not come on when switch on shift lever is pushed. I looked in owners manual for a fuse that might be blown. No luck. Any ideas.

Ok, remove the steering column upper shroud and inspect the orange wire for a break in the wire between the shift lever and the electrical connector on top of the steering column. It's common for these to break as the shifter movement weakens the wire and eventually it breaks. If that's the case replace the shift lever (comes with new switch and short harness) and retest.
