45,000 Mile Major Service - Really Needed?


Recommended Posts

Posted

Depends on what the manual says. My last several cars transmission service were recommended at 60K at the recommendation by the dealer. That was the severe duty recommendation. The last new truck I kept passed 100K miles was an 04 Z71. It was 150K for trans and anti freeze change recommendation. I gave it to my son. At about 200K we traded it in with the same spark plugs, never had a problem with it.

I'm ready for my 45,000 mile service. But I'm wondering if its all really needed. It will be an expensive service if everything GM suggests is performed...probably around $750.

 

The 45k service calls for:

 

-Oil change and filter.

-Cabin air filter replacement.

-Engine air filter replacement. (Looks clean to me...)

-Transmission fluid change.

-Transfer case fluid change.

-Brake fluid change.

-Evap system inspect.

How did I miss this thread? 

 

-Oil and filter change if you do them yourself keep doing it, why pay them.

-Cabins filter, it has been covered, very easy and you can get new filters for a low cost on Amazon. Around here I do mine annually, they get full fast.

-Engine air filter, they are not expensive either and I change mine out every 20k. Around here the dust clogs them up even though they look clean.  Just tap them out on a dark surface and watch what falls out.

-Transmission fluid.  To me general rule for this is every 50k.  Well worth the cost and Grumpy covers it in his post pretty well. Either do it yourself or take it in to have done.

-Transfer case, you can do this yourself as well.  Easy to accomplish.

-Brake fluid.  How important is it to you that your vehicle stops when you want it to?  I usually do brake fluid when I do my brake pad replacements. But then my 02 silverado is still on the original front pads at 183k miles.  So I have done my fluid twice before now and used ATE Super Blue, which I now see is no longer legal in the US for some reason.

-Evap system?  I can't say much on here other than a good visual will not really tell much.  You don't hear much of this system going bad.

If a guy drives home so drunk he can't walk for ten years without incident; does that make it a good idea? 

Gee wiz ( grumpy) it was an example of which I could give countless. I realize you were a blender. I was an end user and a oem of quite a few of equipment manufacturers to install my product. My family business is held in high regard in our field. Oil testing is a frequent occurrence in our field. Our Hwy is paved in dirt and mud. Our horsepower is from 150-1000, to operate our product. My example was the recommendation of GM and Hyundai among others. I wouldn’t be foolish enough to use my own testing results. I’m sure your testing is more intense than theirs.

I know a guy who owns a trans shop, has a 87 silverado with over 350k miles (that was back in the early 2000s) he said trans fluid at the first 30k to remove any break in friction material and 40 to 50k after. He never had to open up that trans at all. If you dont do your trans at 45k or sooner it will fail. You do so tlc it will not. I do my own driveline fluids myself in amsoil.

That schedule sounds reasonable. I plan on having my trans done every 50k, that's good enough.

OP here to give an update!

 

Wow this thread is still alive.

 

I ended up not doing the 45k, despite warnings otherwise. Then, out of laziness, I went ahead and never did any other service intervals after that either. So now I'm at ~140k and everything still works great.

Dumping the truck soon though because its cosmetically wasted, so there probably won't be any updates after this. Sorry!

Thanks for all who commented.

And we meet Mr. Joe Average living in his throw away society. Someone else's problem now, eh? Thank you for your contribution.

I actually just did the trans fluid/filter, brake fluid, transfer case and front/rear diff fluids albeit at 60k miles and not 45k. My truck shifts so much smoother now. It was starting to get those hard shifts the last few months or so. I drive on the beach a lot so the fresher the fluids the better imo. Never know where sand gets into.

Dad's brother, my Uncle recently retired from White/Volvo. He delivered parts all over the USA in a Chevy 6.0 3500 van. When he took the job he insisted that he be allowed to do his own maintenance.  Trans at 50 and 100 K and then 100 K after that. Full Synthetic fluid. Motor after break in at 10K intervals also full synthetic. While the service department serviced trucks were running a around 200K before they choked and puked Uncles were still in service uninterrupted by motor or transmission issues for over a half million miles two consecutive vans and then 350K on the third when he retired. For what that's worth.

One factor that is not the same across the board is the way the vehicle is driven.

So many variables.

From cold starts, to jack rabbit starts.

City miles or highway miles.

Flat ground or mountains.

Driven like it was stolen or flat tracking.

Etc., etc.

Lol. Funny read, But you work in the said industry where you earn a living from it. I supposed that's from one perspective.

Heck the health industry was wrong about the four food groups, after years / decades telling kids that the four food groups is how they should eat and categorize this foods. Aren't there so called health professional or whatever they call themselves? Lol how did they go wrong there??

Of course if money wasn't an issue couldn't you change it every month? Would that cause problems too it just when it reaches too high of a milage.

Just saying.. I personally don't have an issue going to a shop and getting the fluids that I can't do done on time.


 
WOW!, Thanks!!!!! You have me convinced that I should ignore 45 years of transmission rebuilding experience, multiple articles published in transmission digest, working with multiple transmission part manufacturers to develop solutions, and running the largest transmission re-manufacturing line in the state. Thank you for your infinite wisdom... :nonod:

these are all easily done in a home garage in a couple of hours.

 

This. I haven’t looked but I’m sure there are 15 videos on YouTube telling you exactly what you need to do. Cabin and engine filter will be $15 a piece. You’re probably $55-65 for full synthetic oil change with a top tier filter. Not sure on the cost of the other fluids. Let’s just say you’re $175 total in parts and supplies (even though I think it’ll be less) and 2 hours of labor. 

 

 

Eta just saw this was a way old thread and OPs update. Lol

    • That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
