    2001 Silverado 2500HD 4WD, SB, 4dr, 4.1 axle, 6.0L engine, auto, snow plow prep. Picked it up just a week ago. LOVE IT!! We'll see how things go as I rack up the miles. Not happy with the Chevy splashguards -- not long enough to keep the mud (and my gravel driveway) from hitting the rocker panels. Would have preferred the painted running boards, but told by the dealer that they wouldn't work with the wheel flares (which come standard). Opted for wheel-to-wheel step rails, due in a week. Also planning on getting a rhinoliner. Anyone had any experience with them?

    Have had my rhino liner since april of 2000.

    Its great

    No negative things to report about it

    Last I heard it was a 1500. Or are you wishing you bought a real truck? haha
  • rayt2rayt2 Posts: 1,208
    Go to my photo album and take a look at the mud flaps I installed (they would be under the Borla photos), they are readily available at any good auto parts store (Autozone, Pep Boys, etc) and the install involed no drilling into the truck metal I used all existing holes to install, they are 100% better then those preformed ones that do diddly when they are needed most, cover more surface area and don't trap dirt behind them as the preformed do.

    I think you met to respond to jovanotti in regards to the splash guards. If you look at my pics I didn't have any when the pics were taken but I have since put on the "preformed" guards and they seem to work pretty well.

    jovaotti,I also did a spray in liner but I did line-x. I think the bigger name liners all hold up good but I could be wrong.

  • rayt2rayt2 Posts: 1,208
    Be sure to check behind those preformed mud guards now & then because they do tend to trap dirt/sand/grit between them and the body making the paint prematurely wear off and rust to invade the space.
    Been there done that....

  • I'm thinking about the Duramax-Allison LS/LB for towing a 30 ft Sunnybrook 5th. the max the 5th can weigh loaded is 12,700. I hope to stay at least 1000lbs below that. I'm getting scared about the fuel mileage reports with the 8.1 gas, and I'm going to be "fulltiming it". that's why I'm thinking Duramax. I have no diesel experience at all so any input is welcome. I have a couple of friends who say diesel!! Anyone out there towing with this with at least a few months on it?

  • ryanbabryanbab Posts: 7,240
    ask the salesman to see the invoice of the truck you want to buy (shows how much the dealer pays for the truck)
  • gator34gator34 Posts: 3
    Just bought my 2500HD ext. cab, 6L, 4x4, LS. Paid about 700 under invoice & about 4200 under sticker. They're trying to sell fast to make room for the 2002's. Good luck.
  • mrbergmrberg Posts: 2

  • Left the truck in the driveway for a week and when I started it, the transmission wouldn't go into gear. Brought it into the dealer and they told me this is a defect in the transmission. It seems that the fluid drains into the pan and creates an air pocket. Called GM complaint central and they agreed. Problem is they don't have a fix. Anyone out their with a similar problem. would appreciate your comments.

  • indian4,
    I encountered the same problem with mine. I have a 2500hd with allie and 15K miles so far and love everything about except that problem of leaving it set for awhile. There are two filters in this tranny, the one you can see and change (control main oil filter, a spin on) and one that is similar to all other auto trannys (suction filter which requires pan removal to change). I agree there is no EASY fix to this problem which is really no big deal, heck we only pay 30K+ for these vehicles. I think there needs to be a check valve (or flapper valve) somewhere between the coverter housing and front support module to prevent the oil draining from the directional flow control valve to the pan. I haven't had it for about five months now but when I did have it I simply moved the shift selector from reverse to low twice and it got me moving again, I think this directs the flow the fastest from the pan back into the flow control module.
  • Hi all...we took delivery (only waited 4 weeks and a day) about a month ago and have put 1500 trouble free miles on our 4 X 2, 6.0, auto (chevy), crew cab LB. I am happy so far besides the dealer lies and mistakes...clearance lights were missing on delivery and they refuse to put 'em on and they lost our discount coupon (my step-brother works for GM and we got such a deal it would make you sick) and found out the salesman tried to use it again for a friend of his..GM came down on them hard and fast...BOOM. They really got spanked! Put 25 110 lb bales of hay in the other day..didn't even know they were back there till I got home and had to unload 'em all..damn horses!....Oh yeah..4 tank fulls getting about 13.5 MPG
  • go to post your lemons here board if you dare, I had a 2k ls with 6.0 and loved it , bought this 2001 lt to spoil myself and it was a nightmare.picked up a 2002 2500hd LS 6.0 and i am back in dream land and getting more that 8mpg again , thank god
  • I bought a 2002 Indigo 2500HD 4x4 6.,4.10, Xcab,SB and I love it. This is the smoothest driving truck yet. I bought it 8/23, and have 4300 miles with 0 problems. I will use it to pull my snowmobiles, and they seem like nothing for this truck. The 4.10 gears work well, and I still get 13-14 mpg on avg.
  • Hi - trying to find out if the dealerships are trying to put it to me (being a girl - you know how it is) . . . have a 01 HD w/ 8.1, Allison tranny, 3.73, crew cab. (forest green by the way - very nice!) . . . check engine light came on - took it to dealer who said it is within GM spec to burn 1 qt oil per 2000 miles. Sounds like a crock of &*(@ to me, and want to know if anyone else has had this problem (if it is a problem) and what's going on . . . (7900 miles by the way)

    In accordance with GM tsb no.01-06-01-011

    "The accepted rate of oil consumption for engines used in the vehicles referenced is 0.946 liter (1 qt) in 3200 km (2000 mi). This rate only applies to personal use vehicles, under warranty, maintained in accordance with the appropriate maintenance schedule, with less than 58,000 km (36,000 mi), or 80,450 km (50,000 mi) for Cadillac, driven at legal speeds in an unloaded (for trucks) condition."

    What's funny is that it is the acceptable rate up to 36,000 miles at which your warranty expires. Does that mean it becomes unacceptable once that happens?.....hmmmm..
  • Very interesting - especially the last note - what happens to oil consumption after 36K? Nothing published on acceptable levels? What is tsb no. 01-06-01-011 (where did you find it?) Forgive my ignorance!

    Full TSB:

    File In Section: 06 - Engine/Propulsion System

    Bulletin No.: 01-06-01-011

    Date: March, 2001


    Information on Engine Oil Consumption Guidelines

    Models:All 1996-2001 Passenger Cars and Gasoline Powered Light Duty Trucks Under 8500 LB GVW

    This bulletin is being revised to add Model Years 2000 and 2001. Please discard Corporate Bulletin Number 76-60-04A (Section 6 - Engine).

    All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the power stroke, part of this oil layer is consumed in the combustion process. As a result, varying rates of oil consumption are accepted as normal in all engines.

    Oil Consumption

    The accepted rate of oil consumption for engines used in the vehicles referenced is 0.946 liter (1 qt) in 3200 km (2000 mi). This rate only applies to personal use vehicles, under warranty, maintained in accordance with the appropriate maintenance schedule, with less than 58,000 km (36,000 mi), or 80,450 km (50,000 mi) for Cadillac, driven at legal speeds in an unloaded (for trucks) condition.

    Many factors can affect an owner's concern with oil consumption. Driving habits and vehicle maintenance vary from owner to owner. Thoroughly evaluate each case before deciding whether the vehicle in question has abnormal engine oil consumption.

    Gasket and External Leaks

    Inspect the oil pan and engine covers for leakage due to over-tightened, damaged, or out of place gaskets. Inspect oil lines and fittings for signs of leakage.

    Improper Reading of the Oil Level Indicator (Dipstick)

    Verify that the dipstick tube is fully seated in the block. When checking the oil level, make sure the dipstick is wiped clean before taking an oil level reading and fully depress the dipstick until the shoulder bottoms out on the dipstick tube. The dipstick should be the proper part number for the engine/vehicle that is being checked.

    Not Waiting Long Enough After Running Engine to Check Oil Level

    The vehicle should be allowed to sit for at least 5 minutes (20 minutes for the 3.4 L LQ1), after the engine has been shut off, before taking an oil level reading to assure the oil has had enough time to drain back into the crankcase. In order to ensure accurate results, the temperature of the oil should be close to the same temperature as the last time the oil level was checked.

    Improper Oil Fill After an Oil Change

    Following an oil change, verify that the proper amount and type of oil was put in the engine and that the oil level on the dipstick is not above the full mark or below the add marks. Refer to the Owner's Manual or Service Manual for information on recommended oil quantity, viscosity, and quality.

    High Speed or High RPM Driving

    Continuous driving at high speeds/high RPMs may increase oil consumption. Because this may not always be an everyday occurrence, it is hard to determine exactly how much the oil economy will be affected.

    Towing or Heavy Usage

    Towing a trailer will increase oil consumption and may cause oil consumption to fall below the normal accepted rate referenced in this bulletin for an unloaded vehicle in a personal use application. Large frontal area trailers will further increase the work required from the engine, especially at highway speeds, and thus increases the rate of oil consumption.

    Crankcase Ventilation System

    Verify that the positive crankcase ventilation (PCV) system is operating properly. Incorrect PCV valves, blockages, restrictions, or damage to the PCV system can result in increased oil use.

    Oil Dilution (Fuel and Water)

    On vehicles that are usually driven short distances, less than 8 km (5 mi), especially in colder weather, unburned fuel and condensation generated from cold engine operation may not get hot enough to evaporate out of the oil. When this occurs, the dipstick may indicate that the oil level is over-full. Subsequent driving on a trip of sufficient length to enable normal engine operating temperature for 30 minutes or more, in order to vaporize excess moisture and fuel, may give the customer the impression of excessive oil consumption.

    Engine Temperature

    If an engine is run at overheated temperatures (see Owner's Manual or Service Manual) for more than brief periods, oil will oxidize at a faster than normal rate. In addition, gaskets may distort, piston rings may stick, and excessive wear may result. Verify that all cooling system components are in proper working order.

    Engine Wear

    Piston scuffing, excessive piston-to-wall clearance, tapered or out of round cylinders, worn, damaged or improperly installed valve guides, seals and piston rings will all cause an increase in oil consumption.

    Measurement of Oil Consumption

    Engines require a period of time to BREAK IN so that moving parts are properly seated. Therefore, oil economy should not be tested until the vehicle has accumulated at least 6400 km (4000 mi). An exception would be allowed only if an engine is reported to be using more than 0.946 liter (1 qt) in 1600 km (1000 mi).

    1. Verify that the engine has no external leaks. Repair as necessary.

    2. Verify that the engine is at normal operating temperature (see Owner's Manual or Service Manual).

    3. Park the vehicle on a level surface.

    4. Wait at least 5 minutes (20 minutes for the 3.4 L LQ1), after the engine is shut off, before checking the oil level to make sure that most of the oil has had time to drain back into the crankcase.

    5. Verify that the oil level is at, but not above, the full mark on the dipstick, and that the proper viscosity and quality oil are being used as recommended in the Owner's Manual.

    6. Record the vehicle mileage, date, and exact oil level on the form included in this bulletin.

    7. Ask the customer to verify the oil level, each time the vehicle is fueled, following steps 1-6 and return the vehicle to the dealership if the oil level is found at or below the add mark, 0.946 liter (1 qt) low. If the oil level remains above the add mark, the customer should continue to operate the vehicle and verify the engine oil level until 3200 km (2000 mi) has accumulated before returning to the dealership for a final evaluation.

    8. If the final evaluation shows that the engine uses more than 0.946 liter (1 qt) in 3200 km (2000 mi), follow the published symptom diagnostics as described in the appropriate Service Manual. If the oil consumption test shows that the engine uses less than 0.946 liter (1 qt) in 3200 km (2000 mi), explain to the customer that their engine meets the guidelines for oil consumption.

    However, this TSB may not apply to your truck since it's over the 8500 LB GVW. I am assuming though, that your dealer is using this TSB as a guideline since I couldn't find one for the specific model that you have. Good luck!!
  • Wow - thanks for the info. This will definitely give me something to go on. I appreciate your help! Hope you and yours have a safe and happy holiday season!
  • kg11kg11 Posts: 530
    I have a Sierra 2500HD 8.1/allison with 14000 mi.The first 8000 mi it used a qt per 1000 to 1200 mi.(lots of towing)But in the last 6000 mi it's only used ONE QUART.Now that it's broke in it don't use oil and no longer makes that annoying knock on start-ups.
  • Do you ever get sluggish shifts from the Allison? Seems like my catches every now and then. I also haven't done any towing - so I guess I'll see how that goes over the next few thou miles. Have a friend of a friend who has a Suburban with the 8.1 - they got a new motor out of Chevy when theirs kept eating the oil. ???
  • Can anybody advise me on their circumstances that resulted in GM buy back their 25ooHS?
    If you can please email with details or post.
    I am in the pre arbitration process with BBB, and need some more evidence to support my claim.
  • Can you give me some info on this repurchase so I will have some ammo going up against GM through the BBB
