So I am looking to try to get into a Sierra SLT, very low miles, around or under $20k. For that money, I am thinking I will have to go with a 2007. 2007 was the first year of the "new" body style right? Anything I should be aware of being the first year of a redesign?

 

Also, I will be doing tons of highway miles. What were the axle ratio options for 2007? Did they change any for 2008?

 

Thanks!!!

I know work trucks have a 3.23, thats pretty low.

 

The rest you can usually get a 3.42, 3.73, and 4.10

 

Seems like most people on here enjoy the 4.10 or 3.73 the most though :dunno:

 

Even with the 5300 V8 having a 3.42 axle is fine from my experience.

 

Good luck on your search, and when you buy, make sure to post some pics of the new ride!

I have a 2007 Sierra SLT and have not had a single problem with it! Kind of depressing to think it would sell for under $20K though!

 

I have the 3.73 gears and get just under 20 MPG straight highway (75 MPH) and a fairly consistant 16 MPG straight city. It does improve in the summer so I'm looking forward to warmer weather! Good luck in your search!

I would enjoy the 4.10 or 3.73 but this will be a Highway rig so I need the Highest (numerically lowest) rear end I can get. I have heard mention the 3.42. Was a 3.23 an option in 2007/2008?

 

Did they have the active fuel mgmt in 2007?

 

I will have to find the RPO codes for the rear axles and the active fuel mgmt engine for my search on the used lots.

 

Thanks!

Active Fuel Management was available in the GMT-900 body styles. It was available in the 5.3 & 6.0, I have it in my 6.0 but when I got my Black Bear Tune I turned AFM off. I have 3.73 in my V-Max and I get about 18-19 mpg on the freeway at 65mph.

My 2007 has been trouble free. In today's market, you should be able to find a nice 07 for 18 grand with reasonable mileage. Anything under 50K miles is about right for a 2 year old truck. Many in here don't like AFM. but that's about the only real complaint other than some early production oil leaks that were normally taken care of by the warranty.

 

I highly recommend a GMT900 truck.

The GMT-900 trucks with a 5.3 all have AFM with either flex fuel or not.

 

I get decent gas milage with my 5.3 and 3.73 on both city and highway. Summer MPG (if I baby it) 17.5 / 19.5

Most of the trucks you will find are going to have 3.73s if it is an extended cab or crew. Especially if it has 20in wheels, which a lot of the SLT's do. What are you looking for, single cab, extended, crew? Around this area it's going to be hard to find a Crew Cab SLT or LTZ for under $20,000 with low mileage. But trucks are still going out the door about as quick as cars.

 

I have an 07 GMT900 Crew Cab and I have no complaints. I absolutely love it. I have the 6.0 with 3.73's. I have got as much as 21mpg on the high way on about a 200 mile trip, but I was being good at a steady 65. If I go over 72mph which is a hair over 2000 rpm my truck does not like it. Oh, it runs great there, but mileage will fall to 17-18.

 

 

 

They are great trucks. You will love it.

My 04 ext cab SLT has 3.42 gears and I love it on the highway. about 1750 rpms at 65 and it'll cruise at 20mpg all day long. Whatever you decide I would make sure you get the active fuel management. I know some people who didn't get it on their new trucks and they wished they did. (their friends do 4mpg or better on the highway)

 

I would shop around. $20k for a truck is a lot to spend considering that with the red tag they had going on you could get a truck for $10k off sticker new. That just reduced the prices of the used ones.

 

As an example, local dealer has an 07 Silverado ext cab 5.3 LT1 package with 43k for $16k. They have a 4wd almost 53k same year for $19k. Didn't look to see if they wer nbs or classic.

Thanks for the input! I can find the "classic" 2007 for like $13-$16k with 25k miles. I want the NBS though, and of couse I am seeing those are around $25k for SLT and under 20k miles. Seems high to me as like Mike said they were doing all the employee pricing on them.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.

      That makes sense, and I agree with most of that.   I think the product would need both: 1. a default powertrain template, so it is useful out of the box; 2. user-selected priority parameters, so the owner or shop can choose what they want to see first.   Different users are going to care about different things. One owner may care about oil pressure and voltage. Another may care about misfire trend, AFM/DFM behavior, or U-codes. A shop may want communication events and repeatability first. Your baseline point is probably the most important one. Raw data is not very useful unless the report can show what normal looked like for that vehicle under similar conditions.   The way I would think about it is: - start with a basic known-good baseline - learn normal behavior for that specific vehicle over time - allow the event to be overlaid against baseline - show whether the event was a one-time spike or a repeatable pattern - provide a simple severity level, but with clear limits on what that severity means   For example, early severity could be something like: - Info: event captured, no obvious abnormal pattern - Watch: value moved outside baseline, but not repeated - Warning: repeatable abnormal pattern under similar conditions - Critical: communication loss, voltage drop, bus-off, reset, or severe repeated event   I would not want the first version to say “replace this part.” That would be overclaiming unless there is repair-confirmed data behind it. It would be more honest to say “this pattern deserves inspection.”   On the OBD port question, I think OBD absolutely has a role. OBD is probably the right place for: - DTCs - freeze frame - VIN - calibration information - normal scan-tool parameters - Mode 6 / enhanced diagnostic data if available The reason I am still looking at an ECM-side recorder is that the failure may happen before anyone connects a scan tool. If the owner plugs in a scanner after the event, the pre-event evidence may already be gone unless the ECU happened to save it. So I do not see this as “OBD versus ECM-side.” I see it more like: - ECM-side recorder: always armed, rolling buffer, event evidence - OBD/DLC companion: DTCs, freeze frame, VIN, calibration, normal scan data - phone/cloud: status, notes, upload, report generation, notifications   I agree that phone connection and push notifications would be useful. I just would not want the phone or cloud connection to be required for capture. The recorder should save the event locally even if the phone is not connected. The phone should help with event marking, download, notes, upload, alerts, and report viewing.   For a default GM V8 event report, would this list make sense? - RPM - calculated load / MAP - throttle position - vehicle speed - gear / torque converter state if available - coolant temperature - oil pressure - oil temperature if available - battery voltage - commanded AFM/DFM state if available - actual AFM/DFM state if available - misfire counters / roughness by cylinder if available - fuel trims - relevant U-codes / communication events - bus-off / lost periodic message / module reset / voltage drop events Which of those would you remove, and what would you add?

      OCI, not when but why?

      By Grumpy Bear · Posted

      I went to the county a few years back to dispute my property taxes. To do that I hired an appraiser and a lawyer. The County Assessor wished to argue that the homes in my neighborhood the appraiser used were all 'distressed properties" and not representative of the "Market Average".    My response was," Of the 50 homes in our subdivision 43 of them were "distressed properties" under bank foreclosure and as such "Distressed IS the market". Lawyer about choked on his coffee and handed the Assessor the 'receipts'.    I won that case on the evidence provided by the Lawyer and the Appraiser.    We have the same thing going on here. My statements were based on the GOVERNMENTS NATIONAL DATA and yours on local markets in areas of your interest. They are both correct....   Thing is, this divergence was based on NATIONAL and not on LOCAL. I think you even understand that. But like you said, we are both stubborn and hardheaded.    I do not see any advantage to disengagement.  But that said we can step back to compose ourselves.

      Looking at ordering a '26 WT because I want a std cab, std bed

      By revmanii · Posted

      Trust me I appreciate the comments and concerns. It's what I was looking for to help me evaluate the situation and what I want to do. I have decided to move forward with the BORA hubcentric slip on 3/8" (.375") with the extended lugs nuts. Fedex says they should be here Monday :). Meanwhile, the dealer got the remote start and Patriot spray in bed liner done over the last couple of days. Also, I installed an inline stop/start eliminator today. Starts back up in what whatever mode you shut it off in, so you don't have to hit the button every time you fire up.
