Just turned 100k. Even though this truck has been meticulously maintained and never abused, it has had the transmission replaced (at 67K), sound system (at 25K), intermediate steering shaft (3 times), HVAC controls (at 75K), front rotors (2 times), instrument panel (at 70K), steering wheel control modules replaced (80K), etc. There is so much slop in the drive train that I would never consider using as a tow vehicle. Good for going to the dump and grocery shopping. Limited slip (rear) is demonstrating signs of impending failure, just a matter of time.
Aftermarket navigation system and Magnaflow exhaust. Auto headlights. The 5.3 is a fantastic engine. 4-wheel anti-lock disc brakes work very well when the front rotors are still true.
GM needs to admit the 4L60E transmission is fatally flawed and fund repairs.
