Transmission problem
2002 Chevy Silverado V8 Four Wheel Drive Automatic 87500 miles

My tow/haul light doesn't come any longer nor does the truck shift down when I press the button. Can you tell me what the problem might be? Thanks in advance.

First thing is to check all your fuses. This is the easiest and cheapest problem to fix.

If it is not the fuse then you might need to remove the plastic steering column cover. At the end of the shift lever you will find two small wires that are for the tow/haul button. These wires get brittle and break over time from shift lever movement. You will have to repair the broken wire if this is the case.

Post your results and I will follow up.
