Edmunds' Expert Review

Pros
- Class-leading engines and hauling capacity, roomy interior, superior brakes.
Cons
- Unproven engines and drivetrains, cheap interior materials.
What’s new
Both light- and heavy-duty 2500s sport new torsion bar front suspensions. Light-duty models now offer optional traction control and standard child safety-seat tethers. Heavy-duty Sierras are completely redesigned for 2001 offering two new engines and transmissions, bigger interiors and numerous other improvements aimed at buyers looking for a "professional grade" truck from GM.
Edmunds says
With both a light- and heavy-duty version, GMC's 2500 series Sierra offers just about every option you could ask for in a full-size three-quarter-ton pickup.

Vehicle overview
If you're looking for flexibility, capability, and a "professional grade" image, look no further than GMC's 2500 Sierra. Available in either light-duty or completely redesigned heavy-duty versions, these versatile trucks come in a variety of configurations and trim levels to suit just about anybody's pickup truck needs.
Like the 1500 Series, these trucks share platforms and componentry with Chevrolet's Silverado, but Sierra gets some styling and feature enhancements to position GMC as the "professional grade" truck. Looks and special content aside, the biggest draw for GMC's big pickups are their exceptional powertrains, outstanding payload capacity, and unparalleled towing and hauling ability.
At the heart of the heavy-duty Sierra's redesign this year is the availability of two new engines and transmissions. The Duramax 6600 is an all-new turbodiesel V8 developed jointly with Isuzu that cranks out 300 horsepower and a whopping 520 foot-pounds of torque. (That's 65 horses and 20 foot-pounds more than Ford's PowerStroke, and 55/15 over the Dodge Cummins diesels.) When it comes to gasoline power, GM leads the pack there, too. The all-new Vortec 8100 V8 puts out 340 horsepower and 455 foot-pounds of torque - both numbers eclipsing those of the V10s being offered by competitors. Even the base Vortec 6000 V8, available in both light- and heavy-duty versions, has been juiced to 300 horses.
Heavy-duty models offer an electronically controlled Allison automatic transmission that boasts a patented "grade-braking" feature that automatically finds the optimum gear to supply downhill engine braking without manually downshifting, allowing you to concentrate on the road. It also touts "shift stabilization" to prevent ill-timed upshifts and downshifts, and even has bolt-on "Power Take Off" capability that allows owners to run PTO-driven equipment on-site, delivering 250 foot-pounds of continuous torque.
With comfy seats and plenty of the latest features, the redesigned heavy-duty Sierras sport roomier cabins with increased head, leg, and hip room over their predecessors. Light-duty 2500s carry over interiors from last year with child safety-seat tether hooks constituting the only new feature for 2001.
While we're not sure if the evolutionary styling of the GM's heavy-duty pickups carry the brute appeal of a Ford Super Duty or the big-nosed 3500-series Dodge, we do know that they will beat them when it comes to good ol' pullin' and haulin.' Even if you decide to stick with the somewhat more tame light-duty version, the 2500 Sierra still provides all the power and capability you'll ever need along with a comfortable interior and a smooth ride.

M. Fisher,04/05/2002
2001 GMC Sierra 2500HD 4dr Extended Cab SLT 2WD SB w/OnStar (6.0L 8cyl 4A)
My GMC is equiped with the 8.1 liter
engine and Allison 5 speed
transmission. I tow a 26 foot travel
trailer and cross the US frequently.
The trailer weighs 7500 pounds, loaded.
I have had no problems with performance
and it has ample power in the mountains
(Rockies). The only down side was the
difference in the cost of oil changes
at GM dealers. High of $32 low $17.

2001 GMC Sierra 2500HD 4dr Crew Cab SLT 4WD SB w/OnStar (6.0L 8cyl 4A)
This last year has been quite
another story. I've had a complete
Brake job including replacing all four
rotors which were fine 2500 miles
before. The sudden complete failure of
all four brakes cost 1600 dollars for
that. The four wheel drive switch has
gone twice causing the truck to shift
in and out of gears and fall out of
4WD. This also caused premature wear …
of the U-joints, which needed
replacing. The fan motor now is going
and needs to be replaced. The engine
burns a quart of oil every 2200 miles
and knocks like mad for the first five
minutes of run time until it's warm.
The engine also knocks if I use any gas
other than premium.

This is one awesome truck. We are
appreciative of the creature comforts,
all around visibilty, safety/security
features and OnStar. I pull a 30 foot
5th wheel, (about 11000 pounds) and
have been very impressed with the
trucks ability and ease of
maneuverability. I regret I didn't
wait for a DuraMax, but I'm getting
along fine without it.

2001 GMC Sierra 2500HD 4dr Extended Cab SLE 2WD SB (6.0L 8cyl 5M)
For a top of the line truck that listed
for over $32000 new you would think the
company would put in better seats ;such
as more padding in the bottom seat and
go back to having the whole seat move
by power not just the bottom. (this is
for the cloth seat). the seats in my
1997 were more conforbly , other than
the seatr it is an excellent truck.

Should I lease or buy a 2001 GMC Sierra 2500HD?
Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
