2000 GMC Sierra SLE 6.0L Vortec from North America


This truck does not make the grade


Transfer case burned up at 97,000 miles. The mechanic who rebuilt it said that the transfer case gears are always in motion, whether you're in 4-wheel drive or not, and that some lever inside beat a hole in the transfer case cover which then leaked all the fluid and it burned up. He said he sees this a lot. I'm wondering if anyone else has seen this?

General Comments:

I have put a lot of miles on this truck, but have followed the owner's manual maintenance schedule religiously and I feel that a $2,200 problem on a three year old truck is ridiculous.

I am a general contractor and I take care of all my tools and they either last or I look for a new supplier. This tool did not last.

Would you buy another car from this manufacturer? No

Recently I got the "service 4wd" message on the dashboard, I wonder if it's going to be a similar problem.

My 2000 Sierra transfer case locked on the interstate yesterday with 62,000 miles.

It took out my transmission and drive shaft.

2000 GMC Sierra SLE Ext Cab Z71 5.3L from North America


Some problems, but a GREAT Truck


I had the drive shaft slip yoke lubricated 6 times before I could convince the GM Tech Rep that there was a problem. I finally got them to replace the slip yoke. When the truck had approximately 20,000 miles on it, I brought it in for an oil change, and the dealer told me that I complained about the throttle body sticking and they replaced it under warranty. I have since had that throttle body replaced at 50,000 miles.

The biggest problem I had was... 41,000 miles, the oil cooler in my radiator developed a leak and drained my transmission of Automatic trans fluid. This in turn, caused the transmission to eat itself. Fortunately, I had purchased the extended warranty because I have been complaining about piston slap since I bought the truck. Otherwise GM was going to make me pay for half the repairs. The dealer sent my truck out to a trans shop for inspection, and three weeks later I got it back with a completely rebuilt transmission and a new radiator. The next day I brought it back because of extremely hard shifting and a trans service light, to have the valve body replaced. Then I brought it back again because they forgot to hook up the vacuum line to my front differential, giving me a service 4WD light.

After all of that, and I am still complaining about hard shifting, I made GM give me a 100,000 mile power train warranty.

I have also had the front break calipers lubricated because of the brakes grabbing.

At 52,000 had the parking break shoes replaced at dealers expense.

General Comments:

Aside from the problems I have had with the truck, I still love it.

The engine has balls and it sounds great even with the stock exhaust and intake.

I am thankful for the auto 4WD on my pushbutton transfer case because the rear does get loose on wet roads.

Besides, hell will freeze over before I buy a Toy-ota, and I'd rather push my Sierra than drive a Fix or Repair Daily or a Dodge.

Would you buy another car from this manufacturer? Yes

This person was obviously not a mechanic. You would never have to lube brake calipers because the pistons inside the caliper are self lubricating as in any type of brake caliper. I would dismiss most of his comments referring to the mechanical reliability seeing how he let his transmission run out of fluid.
