2009 3500 HD Dually with 6.0 Gas engine. At 100K miles the truck got a crate motor from GM and a Crate transmission. It was an extended warranty deal. At least that's what the previous owner said. The engine runs like a top, plenty of power and no noticeable oil consumption. At 215K miles I lost the transmission. Shifting hard, not shifting at all, revving up and BANG into gear from standing start. My transmission shop dropped the pan and there was plenty of metal to go around. Shop recommended buy a reman from one of the reman places..... he said they can do it better than I can due to volume, they do more, it will be faster and the also have a longer warranty than I can provide (3 years 100K miles). I contacted 3 of them, Powertrain products, Jasper and one other.... Jasper wasnt the cheapest but they had a gearbox on the shelf. Had it installed, programmed and it worked like a Singer sewing machine..... until it didnt. At 5000 miles and 60 days into our relationship......slipping in 5th and 6th gear. So there it sits,,,,,in the shop, no transmission in it, waiting on a replacement transmission from Jasper. If you search Jasper horror stories there are plenty, But in my case .... at least so far.... they are honoring the warranty without issue, Granted they dont have one on the shelf so it will be 2 weeks with out my workin truck...that kinda sucks, But here is my concern: My truck seldom goes down the road without a trailer behind it, either a tractor, skid steer or mini excavator. I know that this truck tows, tows heavy and tows often. My question for this group is as follows; Am I pissing in the wind letting Jasper replace this transmission? Am I likely to be in this same boat in another 5000 miles? Does anybody here have a line on a better transmission builder? I am thinking about asking Jasper to upgrade the clutches in this one on my dime..... Its not so much the money, its the down time that hurts me.

I am using a gooseneck dump trailer, I have never seen a 5th wheel dump trailer. I cannot imagine why a 5th wheel could tow more than a gooseneck. Please explain.

I have been towing a dump trailer loaded with limestone and sometimes mason sand behind my 3500HD truck. I have no problems whatsoever towing, but I am often dragging 16.000 lbs or better. I just looked up the manufacturer specs on what this make and model truck can tow..... 9200 lbs. WOW..... I look up a 2021 3500HD and of course I see a configuration up to 36,000 lbs. So the obvious question here is - - What the heck is so different about a 2021 one ton dually that allows it to tow 4X the weight of my 2009 Dually? Anybody out there care to speculate? I see trucks like mine hauling a lot more weight than I do without trouble. What gives?

2009 Silverado 3500HD DRW Gas: Code P2771, Service 4wd Light illuminated. Shifter knob buttons illuminate at engine start but immediately extinguish. Here's what happened; I used 4Hi to get out of a sticky spot - I did my usual coasting in neutral return to 2wd shift. When I got on hard pavement and took off....it was evident I was still in 4Hi. I pull off to the side of the road and started screwing with the knob trying to get it to shift OUT of 4Hi when it shifted into 4L and hasn't budged since. I read the code: 4WD Low Switch Circuit. (Okay Duh...its stuck in 4LO so yes its gotta be that!). No amount of monkeying with the transmission (shifting fwd to reverse & neutral) while working the transfer case shifter knob has any impact. I cleaned the grounds at the frame, they are all bright and make a solid ground. No Joy. The 30 AMP fuse in position 67 (TREC) has not blown. Is there another fuse that operates the transfer case? I cannot find it if there is. I replaced the shift motor with a brand new AC delco unit. No Joy. It is important to know that the transfer case position indicator light does NOT light up (indicating that the TC is in 4LO) - I know that the light in the switch is good because it comes on when I start the truck, BUT: Normally there is a tell tale amber light showing that you're in 2HI or 4HI or whatever. Another symptom of this is that my speedometer is reading ZERO when moving in 4LO. I also disconnected the battery for 30 minutes etc... trying to re-boot the computer hoping that might do it. No luck. While changing the shift motor I did check to see if I could manually move the shaft that the shift motor turns and it does not appear to be jammed in any way. IF I KNEW WHICH WAY to turn it, I would at least manually shift it out of 4LO so that I could at least drive it! PLEASE somebody who has experienced this before help out and tell me what's next!

I bought a 2009 LTZ 4wd and the PO has 19.5' aluminum wheels on it. I am looking for stock wheels. These are way too big. 245 70 R19.5 plus they are hell to balance.

Only a minor annoyance...but why wont my windows work with the key ON and the engine OFF? Left them down and tried to put em up without starting the truck....NO haps. Start the truck, wait about 2 seconds and viola... Anybody ever have this occur?

That's what I like about this site! There is no RPO that describes my fuel tank. All specs alldata etc says it oughter be 26 Gallons. (Yes I am Crew Cab Short bed). I guess Cosmo Kramer here I come. I am going to drive around with my low fuel light on until it quits. Yeah I know I am gonna be sorry too... gonna suck up all the water and goo in the can and maybe even overheat the fuel pump. Hopefully I will just run out of gas though.

RPO Codes beginning with the letter N NA4 NP1 NP5 NT9 Anybody know what size can I have? New to me truck (04 2500 HD 6.0) gives a low fuel light and only holds 20 Gallons. Otherwise the DIC says you got very few miles to empty. My thoughts are that a 22 gallon can is awful small for a 6.0 HD truck. But this seems consistent with the fuel gauge and the DIC. Am I gonna have to carry a 5 gallon can and pull a Cosmo Kramer just to see how low I can go?
