You will have to excuse me but I'm new to this forum and a new owner of diesel and a lot has happened in the 4 months I bought this truck. So please bear with me and someone help.
Quick run down about the truck, 03 Chevy 3500 dually with the Allison in it, bought the truck out of state at a run-a-round dealership in Columbia City, IN while working in Ohio. Drove the truck about 80 miles back to the hotel. Next day at work truck went in to limp mode ended up getting it towed to a Chevy dealership in Lima Oh. Three weeks and 3,000 dollars, out of my pocket, I get my truck back with a rebuilt tranny. Truck ran great, had 172,651 at time of rebuild now has 178,765. Truck started acting up after a long drive 1200mi, Rome New York to Ava MO. Took me 22hrs of drive time with a 10hr nap drove with cruse all the way running 60 to 70mph on all interstate Hwys. Got closer to home on two lanes with hills and curves truck started to down shift rev to 3 grand would take awhile to shift out of gear. Next day went to town check engine light comes on, and wont engage in for wheel dr. hi or low. Got to town and started it back up and ran just fine with no check engine light on. That was on May 26th. Ran great till last weekend was coming from KCMO to ST. Louis with cruse and left a gas station on ramp went to speed up and it didn't have any power. It was increasing so when I got to 60 I left it there and didn't use cruse, would drive and truck would cut out and drop rpm from 1900 to 1600 then pick right back up. Did this roughly 20 times then drove fine for 70 more miles. Got to hotel was at stop light and truck lost all power shifted fine to second and regained power, pulled into parking lot space went to back up heard a loud and hard clunk would not go in reverse just revved up, put in drive same noise and would not engage. I shut the truck off came inside and almost cried lol, I can say that now because its true. This truck is my baby and I love it. Went to work the next day locally in St. Louis area, truck drove fine. Trucks been running fine till last night drove across the roadway to get some items from gas station left it running came out made a pretty sharp turn towards the left and truck felt as if the duels were locked up or locking up. Best way I can describe it is how when a tractor trailer makes a sharp turn and the trailer tires grab and squeal. Same thing put in park shut it off let sit for 10 min or so then fired right back up put in gear really nasty grind and clunk sound, shut the truck off disconnected the neg. battery cables let sit for thirty min. Went to grab a bite to eat and truck ran fine for about thirty min. I stopped at a stop light and lost power,( when I say that I lost power I mean I got my foot off break and gas peddle about 1/3 the way to 1/2 way down and am barely moving) get to second gear truck accelerates fine, drives fine. Got back parked it came inside and cried. Bought the truck for $18,900 put $10,000 down with a trade in of $1500 on my old Chevy, put 3000 more in the tranny. I love this truck, its what I have always wanted. I'm in to deep and don't know what to do. As is warranty screwed me bad, but I'm willing to keep fixing it if its going to be worth it. Also truck is LT model, has the steering wheel controls for the radio work. To rotate the millage reader I have to push the button on the wheel with the gas filler on it. millage reader is always cycling and either lands on Spanish or I think its French. Once since I've owned the truck was the millage reader in English for a split second.
Again am truly thankful to have joined this forum. Sorry this was a book but I wanted to have anyone or everyone who might be able to help me understand what I have had happened and maybe give suggestions to fix some or all the problems. Maybe even point me in the direction of finding out the problems. As of right now I don't know if its electrical or maybe vacuum or the tranny is shot again.

1. Tranny acting up
2. Back tires seem to be locking up when turning both directions
3. Over and under revs on hilly roads
4. Tranny making pops cluncks grinds while shifting sometimes does not engage 5. Millage reader cycles and wont reprogram to English

Truck is stock as far as I can tell, dealer who rebuilt tranny said same thing. When I bought it had PPE stickers on it but I took them off. Don't know if that could be part of it. Just guess that's why I'm here so I will quit speculating and get some answers. Please any and all help will be greatly appreciated.

Next time your truck tells you what is wrong, listen to it. You need to get those codes and write them down. Without codes its just a shot in the dark. But if you remember something about speed sensor codes then you need to take a look at all your speed sensors. If it said something 4x4 then I would start with the speed sensor on the t case, pull it out and inspect it. Also in the mean time trace wires back and look for any damaged or frayed wires that are tied to the speed Senors.

See if you can take it for a drive and get that check engine light to come on. Then have the codes read. There may even be codes stored that a cheap auto parts scanner won't see. You need a tech 2 or at least find someone with a v2 to scan it.

Sorry to hear about all the woes this rig has been dealing you, I too love these trucks and is something I have always wanted, I would be very frustrated at this point too.

The fact the truck had ppe stickers on it bugs me. It may have been used with a ppe programmer and abused :( it sounds like the rear end could be damaged (g-80 limited slip) it also sounds like the parking pawl or gear selector was not correctly re-installed or adjusted properly, this is all just humble speculation, if you have known codes like the speed sensor thing that would definitely be a priority place to start

Mike L is the transmission guru here, his word or idea on anything tranny/chassis related is pretty much a statement of fact, take his advise serious, call him up at his shop on Monday the numbers he can be reached at are in the signature of his posts, Inglewood Transmission, but anyone is really gonna want codes to give solid advise of where to start.

You can get an efi live programmer, a hand held auto cal/flash scanner from a reputable tuner, i am not advocating to up your horsepower and run a tune right now but the devise will read set codes, current codes and stored codes in the ECM TCM and I think the BCM, and that may be a good start for you, it may also be able to set your control center straight once you load the software, but only run the optimized stock tune til you get everything figured out and fixed. Also, when a code presents itself you can check and clear it on the spot, that's also nice to know what's going on and how serious something is.

When my g-80 went out, there were no codes, so something's have to be based off instinct. You may also want to call around to some performance shops, most of the good ones have seen everything, good and bad, and will be willing to share advise, the dealership is going to be pretty worthless at this point.

Best of luck to ya,
