#249 of 655 Express 2500 Info Needed
Jun 17, 2002 (3:01 am)
I am looking at a 2002 Express 2500 LS with 5.7 and 4.10 rear axle. I need the 4.10 axle because it increases towing to 8200lbs from 6500 lbs. I need the 2500 (8600 GVWR) for HD trans. and increased payload and braking power. I have a 1500 series now and have had numerous problems with trans., brakes, battery connections...List price is $31,700. I am looking at below invoice ($27,700) plus $2000 reduction in rebate. I will get dealer price Monday.
Does anyone have experience with the 2500 series in GMS or Chevy vans? Towed with them? Reliability? Should I go to an Excursion or Expedition? Thanks in advance.

I got the 2001 Savana extended passenger van, 5.7L, with 3.73 axle. So far mileage is too low to determine reliability. Unless you really tow a lot, I would avoid the 4.10 axle, a 3.73 will be better on gas mileage and much quiter. Mileage wise I get 20mpg Cdn (17 mpg US). The extended is nice for smoothing out the ride, and the seats are really comfortable. The engine has plenty of power.
Remember that only the 2500 extended "passenger" vans come standard with the heavy duty transmission and heavy duty axle, it is an option with cargo vans (at least in Canada).

They are having more of a problem with the drivers side rear doors than the trans. The trans is going to be lifted from the trucks and suvs so the problems with them should be all ironed out by now. I was told by my dealer that the '03 models will be in in late August with the 8 door models in November. It's all speculation at this point, but I am sure that M is anxious to get the new models out and see their sales go up from the new features they are adding.

The 4L80E heavy duty transmission is a tough tranny. It is only available in the 2500/3500 series Savana/Express, not in the 1500 class vans which have the light duty tranny, and where all the complaints originate. This 4L80E is also standard in their commercial vans with wheel basis of 150 inches and over with GVWR double what the 3500 Savanas are rated for. IF you look at the new information on the 2003 Savanas, they are keeping the 4L80E tranny (the only thing that remains original )and not pulling them as you said from their trucks and SUV's. Why would they do that when for 2001 they did a major upgrade to improve the torque converter for smoother shifting. A few articles I read somehwere in here had comments by tranny shop owners stating the tranny is very durable.

The 4L80E trans is outdated and replaced in the '02 models by the 4L85E trans. It has a stronger intermediate sprag, torque converter and a valve body change to make shift smoother. The 4L80E is the trans that I have in my '01 model Yukon XL 2500 series. All of GM's trannys are the same now. The 4L65E is the light duty trans, and is still being used on 1/2 ton models, in the vans, trucks, and suvs. If they are planning on using the trans from the AWD 4L65E Denali/XL trans to run the AWD vans then they are having problems with the Denali AWD trans, not the regular 2WD/4WD trans. Check the Denali/Denali XL board in the SUV section, and you will see the problems they are having. This only pertains to the AWD units, not the 2WD or the 4WD SUVs. I think the AWD transfer case and internals are over working the LD trans and that is what they are working on fixing. I have a strange feeling it's gonna be a band-aid type fix too.
There is a big difference between the AWD and 4WD systems. Check it out in the SUV section.
I bet you that they will have '03 models on the lots very very soon. You just won't see the AWD units until the bugs get worked out of the tranny.

The full article can be found at.....
For 2002 the 4L80E remained unchanged for the heavy duty version. Why would they change it after a major upgrade in 2001 (torque converter), then go back to it in 2003.
First Look: 2003 Chevy Express and GMC Savana
March 6, 2002
When GM engineers embarked on redesigning the 2003 Chevy Express and GMC Savana full-size vans the mission was clear: deliver more. With the addition of features like all-wheel drive, a left-hand-side 60/40 entry/load door, and unique side-access panels on Express Access and Savana Pro models, these vehicles should impress even the hardest-working commercial customer.
"We're delivering more by providing solutions to our customer's individual business challenges," says Dave Kanous, brand manager, commercial vans. "All-wheel drive allows more efficient travel to and from the job site, while left-hand door and unique side access provides improved on-the-job productivity."
The 2003 Express and Savana also feature upgraded mechanical systems and powertrains to further enhance durability, dependability, work efficiency, and safety. A 200-hp Vortec 4300 V-6 is now the base engine for light-duty G-Series vans in all 50 states, featuring new multi-point fuel injection for smoother, longer-life performance than the injection system previously used in the 49 states outside California. The ugraded "Gen III" V-8 range includes a heavy-duty Vortec 4800, a spirited Vortec 5300, or brutish Vortec 6000.
With 275 horsepower, the Vortec 4800 V-8 produces 50 more horsepower than the Vortec 5000 it replaces and is mated to a standard 4L80-E four-speed electronically controlled automatic transmission with overdrive. Rated at 275 hp 5200 rpm and 285 lb-ft of torque 4000 rpm, this 4.8-liter engine is primarily used for heavy-duty service applications such as in 2500 Series regular- and extended-wheelbase cargo vans (8600-pound GVW), or as the optional engine on 3500 Series commercial and motorhome cutaways (available with regular wheelbase only).

The 4800 in the 3/4 ton models?! Sounds really wrong to me, you can't get that eninge trans combo anywhere else in the GM lineup why would they do it for a 3/4 ton van?!!! If you are buying a HD Van you should be getting the towing and cargo towing ability that you need, the 4800 is under powered for the demands of the 3/4 ton buyers, and I would figure that the 5.3 would be the smallest engine I would want. The base engine in all 3/4 ton trucks and suvs is the Vortec 6.0L why deviate. I have never heard of the 4L80E as a base trans in a 1500 either.
Torque converter is NOT a major upgrade. It is a simple slip in part that couples the motor to the trans. It just slides into the front of the trans. They had to upgrade the thing because they were eating themselves up. In 2002 the truck and suv transmissions got upgraded, and I can't see why they would not continue to use the beefier trans in the vans. Like I said before the new designations are 4L65E, and 4L85E. These replaced the older models with stronger intermediate sprag, and re-calibrated valve body.
#257 of 655 There are no new designations for 2003 (2500/3500 vans)
Jun 23, 2002 (12:14 pm)
As the motortrend article showed....the 4L80E remains the tranny in the 2500/2500 full size van line for 2003. Your comment ..."Like I said before the new designations are 4L65E, and 4L85E. These replaced the older models with stronger intermediate sprag, and re-calibrated valve body." I guess the trucks will always stay one step ahead of the vans unfortunatley. I am only telling you what I read in motortrend and other articles. The new designations may be 4L65E/85E, but unfortunately the full size vans will stay behind the trucks for the latest in improvements (and were going to still see the older 4L80E).
Referring to the tranny as a major upgrade....I meant in comparison to any other upgrades they did on the vans since 1996 (fuel injection, door handles, ignition switch, longer lasting brakes for 2001, etc).
Oh well, guess we will know the truth when they come off the line. It will be interesting to see one. But looking at the photos, they haven't changed much in looks from the previous generation (still the funny rear lights). I think I will wait till the next generation before I sell my 2001....so far I love it!

Did they change the brakes for 2001? Are they that much better than the older ones, or did they just change the brake pad material to get them to last longer?
What did they do to the door handles? I know they have added screws to the inside door handle trim panels to keep them from popping off. Is that what you are talking about?
I have also found articles in Motor Trend and other mags like that print what they speculate, not what is actually going to happen. For the most part they are correct, but sometimes even the auto maker does not know what they are going to do until it's go time. I am not saying that you are wrong, just amazed that GM would keep building a different trans while they can save money by standardizing the parts/transmissions.
