2001 GMC Sierra 1500 4dr Extended Cab SLT 2WD SB w/OnStar (4.8L 8cyl 4A)


The best car/truck Ive ever owned. I trust it to go anywhere.Has towing package but anything 7000-8000lbs fells like a struggle for the engine. Like the 4 wheel disc brakes.Factory a/c delco batteries gave trouble(leaked acid). In 91k miles only 1 visit to dealer to repair abs warning light(abs unit died). The drive train is good(change limited slip gear lube every 30k miles) or limited slip rear can stay locked up after a hard acceleration.)Truck has been lowered 2-4 inches (It sits nice, not too low). Installed airlift load assist air bags for towing/hauling (highly recommended!) Flowmaster 70 series dual side exhaust system. 20 inch centerline wheels. The truck 'Ive always wanted. Very happy.

Best Features

Exterior styling, good paint, very reliable, consistant engine performance, towing package is handy to have. Complete full guage set in instrument cluster, no fluid leaks ever.

Worst Features

Transmission shift program a little funky under certain conditions. Have to keep lubricating intermediate shaft for noise. Factory a/c delco batteries leak and die premature.
