Review of the 1999 GMC Sierra 2500

  • Info is not yet available.

  • Safety
  • Pros

    Great new features, powerful V8 engine selections, modern architecture.

  • Cons

    Design isn't cutting edge, premium brands carry a premium price, why no fourth door?

  • What's New for 1999

    Finally, the decade-old, full-size GMC pickup based on the C/K gets a complete redesign from the ground up. Major structural, power, braking and interior enhancements characterize the all-new Sierra. Styling is evolutionary rather than revolutionary, both inside and out.

Great power with 6.0 liter

Vehicle: 1999 GMC Sierra 2500 HD SL 3dr Extended Cab 4WD SB

ABS electronic module - replaced by dealer in Virgina only problem. Drove 300 miles to pick up - has one of first 6.0 liter engines. Great power. Engine does not show up as option in parts stores until 2001.




Service 4wd light

by on
Vehicle: 1999 GMC Sierra 2500 SLT 3dr Extended Cab SB

4WD light comes on intermittently lately. Poor troubleshooting procedures from a Chilton manual led me to replace the front diff actuator motor. Seems the real culprit is a sticky selector switch. Humidity may be affecting this switch, apparently the resistors are shot for each position and loses ability to keep voltage signal to transfer case module. Original battery lasted 6 years so that was awesome to get over 6 years from a battery. Also developed a leak at the front differential. First thought it was the output seal but ended up being the plastic vent cap that screws into the diff.
