In response to #563, my surburban has a bad "reverberation" when running at highway speeds with the back windows down. In fact, it's so bad it will run you out of the truck. So, needless to say, we keep the back windows up when on the highway. The kids don't appreciate that, but my ears can't take the pounding. I'm one of the 2 guys in here who prefer the manual transmission and after reading about the guy who wore out 3 automatics towing with ford's and gm's, I plan on staying with that attitude. I'm sure the allison is a better transmission, but at 2,000 bucks, it better be. I just don't won't to be the one to pay all that money to find out. Bud

#10 of 1057 MPG's... by 4x4 Nov 27, 2000 (12:03 am)
I would really like to see someone's 8.1L MPG's...everyone keeps saying the mileage will not be too much different than the 6.0..I just don't see it..365CU VS 496CU..I have gotten 14 on highway and 12 city..4Wheeler Mag tested the DMAX and 8.1L and there mileage reports for mixed driving was 15.8-DMAX and 9.1MPG for 8.1..unloaded ext cab 4x4's.. I could see maybe the 8.1 getting better MPG's if the 6.0 needed to work harder to push the truck but i don't see that at all..Honestly, I feel the 6.0 has a lot of power and hauls butt...again if i towed a lot i would get the 8.1/allison combo but the most i tow is a 22 ft bay boat... anyway , I would like to see some REAL LIFE numbers from someone with 8.1 and 4.10...
#11 of 1057 auto vs manual by tnglator Nov 27, 2000 (1:46 am)
I ordered a 2500 HD with a HD NVG manual tranny. Did I make a mistake? I wont be towing an incredible amount at least not for now. Has anybody ever driven the manual, how does it feel? I would appreciate some input while there is still time to change my order if I want to. Mileage i figure would be around the same since fourth in the auto and 5th in the manual are the same and I do alot of freeway driving....please help me out with this decision...
#12 of 1057 4x4 - Heck!! We'd love to -- by n75v111 Nov 27, 2000 (3:46 am)
be posting GPM's for the 8.1 but there just aren't many of us who have taken delivery yet due to the Constraint eairlier. Better note that the MOST of the early 8.1's ordered by Dealers for inventory have the 4.10 gear ratio -- all gm would allow for the non-sold dealer units - think they wanted to show off the power better as if it needed it. EVERYONE - WHEN YOU POST THE 8.1 MILEAGE NO'S BE SURE TO LIST THE GEAR RATIO ---!!!! mth1 -- WHAT GEAR RATIO DID THE CHEVY POWER TOUR 8.1 HAVE????? mth1 -- Glad to see your TPW post. Means maybe my Sept. 05 tpw should show up in about 30 days. (13 weeks and counting) A NEW THREAD FOR THE 8.1 SOUNDS LIKE A GOOD IDEA TO ME WOOLYBACK2 ------- 75v
#13 of 1057 7.4 MPG by botie Nov 27, 2000 (3:53 am)
4x4, I would also like to see the mpg numbers for the 8.1. I am doing my research on buying another Crew Cab, but will probably go with the 6.0 because of mileage. I owned a 99 CC 4wd SB with the 7.4 liter and 3.73 gears and only got 9 MPG in the city and never even got 12 MPG on the highway. I would have hated to see what it would have gotten towing anything heavy. I sure would like to see some numbers.
#14 of 1057 Response to Woolyback2 by loyalgmcguy Nov 27, 2000 (4:09 am)
I had an opportunity to test drive an XC, LB, 2500 HD with an 8.1 and 4.10 gears this weekend. The power and acceleration were very impressive. If MPG are within reasonable limits, I'll buy this combination. Woolyback, I ordered white as well. Hate to complain about a truck I can't even get, but what's the deal with the black flares. My dealer advises they can't be deleted nor removed, only repainted to match. Curious why GMC would do this.
#15 of 1057 I agree by mgdvhman Nov 27, 2000 (4:08 am)
...you need to WAIT!.....how can we give results as a whole when they are barely out? Someones mileage with 4 tanks of gas isn't hardly a good idea of longer term.... By 2002 Model years coming out we will have a better Idea what's up....... - Tim
