Hi Guys,
The "Service 4wd" light has came on in my 2000 Silverado 1500. I have not used the 4wd in a few months and everything seems Ok, except the light being on. The truck is a 2000 Silverado 1500 Z71 with 5.3 engine, Tow/haul auto transmission with 77,000 miles on it. Does this light coming on indicate there is a problem or is just a reminder to do some type of maintenace to the tranny. Thanks in advance for any help.
Steve
