Sorry. Just can't stand when people get hostile for no reason at all. Especially when they end up being completely clueless about what they're talking about but think they know it all.

Nah you're good man I'm on your side haha

This is why I always end up quitting forums when I try to help.

 

For the record, GM dealers (mechanics) take direction and training directly from GM. They don't invent the knowledge or training themselves.

 

I am also not "out of my league". I have access to significantly more reputable information than you. I am also not the one, again, asking the random un-trained internet for advice. Once you start asking forums for advice, YOU are out of your league.

 

As for giving the civil discourse advice, you called me names first. I simply questioned your information in a way that made you feel hurt - probably because it made you realize how unqualified you really are. Calling me names and then going on a diatribe about manners is sad. I'm out on this thread, and yet again another forum I probably could have helped more on.

i changed my oil at 1k but the dealer didnt want to. i told him do it anyway, and used one of my free oil changes. i feel better about it even if it doesnt matter. aside from that i'll probably never touch any other fluids because i'm too lazy and have never owned a vehicle that went over 100k miles, no matter how long i owned it.

 

you can follow the manual, or do your own thing if you want. who cares? change it every 5000 miles so you never ever ever have a part break. for sure.

Just wondering how you have been doing with your trans and diff fluid changes. I just oredered a Wix trans filter and want to get this done over the holidays. I am taking 2 weeks and want to do the diff and trans during that time. Did you use the Mobil 75w90 off the shelf at Wally World for the diff. I have a couple of old quarts that have never been opened I was thinking of using for this. What did you do about trans fluid?

Every vehicle I have bought, I have changed out all drive train fluids before the 1st 5000 miles. Then go to the manual intervals, usually the severe version, as most of my vehicles fall into that category in one degree or another. I have not had a major engine, xfer, trans, or diff problem with a vehicle in well over 45 years. At least with a new vehicle. Used vehicles, I have gotten the resulting problems from owners that didn't follow sound maintenance principles.

 

I haven't used the typical 75w90 off the shelf at WW, but no reason not to. I get my oil and lube products for my personal vehicles thru my commercial oil supplier, none of which are regular off the shelf stuff. But you will do well using something like Mobil 1 75w90. Very good gear lube. You can get the commercial grade Mobil Delvac 75w90 at some heavy truck parts and dealership outlets. You can obtain it in the same squeeze bottle quarts. I would prefer that one. It is very stout. It is the factory fill for heavy commercial truck differentials. I use the same 75w90 that goes into my commercial semi trucks in my Cadillac CTS and my Silverado.

I did my transmission and drivetrain around 15k miles, never did them at 1k miles lol. I'm creeping up on 65k here soon, very soon, so it's time for a service. Need to do transmission, tcase, and both diffs.

 

For the fluids, yes I did use the Mobil 1 full syn off the shelf, but from autozone, my walmart only carries their store brand of gear oil. It has the limited slip additive but I haven't noticed any ill effect on the differential thus far. As for the transmission and tcase I used Pennzoil full synthetic transmission fluid that I got at my local parts store. I believe on this next service I'm going to be using Amsoil for the trans and tcase. Need to order my trans filter and gasket here soon. I will also probably be doing these services over the holidays sometime

      Conditions for Meeting a Cold Start   The ignition voltage is between 10 and 15 V. The barometric pressure (BARO) is more than 75 kPa. The engine coolant temperature (ECT) at start-up is less than 42°C (108°F). The intake air temperature (IAT) is between 2–32°C (36–90°F). The engine is OFF for greater than 6 hours or the following conditions must be met: The start-up IAT minus start-up ECT are within 12°C (22°F). The start-up ECT minus start-up IAT are within 50°C (90°F). Fuel level is between 25 and 75 %.   Circuit/System Verification Verify that all I/M System Status indicators report YES, and that no I/M Test DTCs are present.If any I/M Test DTCs are set Refer to Diagnostic Trouble Code (DTC) List - Vehicle. If no I/M Test DTCs are set All OK. Inspection/Maintenance (I/M) System Set Procedure   Warning: Refer to Road Test Warning. Note: Do NOT touch the accelerator pedal until told to do so. A change in TP Sensor angle or an increase in engine speed may invalidate this portion of the test.   Note: An I/M Test DTC will not be stored or erased from the ECU except at the end of trip processing, which occurs 5 s after ignition OFF.   Ensure that the vehicle meets the conditions for a cold start listed above. If the EVAP I/M System Status indicator displays NO, perform the EVAP Service bay test if applicable. Turn OFF all of the accessories; HVAC system, other electrical loads, including aftermarket/add-on equipment, etc., and open the hood.   Set the vehicle parking brake and ensure the vehicle is in park for automatic transmission or neutral for manual transmission.   Start and idle the engine for 2 min.   Close the hood, release the parking brake and Accelerate at part throttle to 72–80 km/h (45–50 mph) with this speed maintained until the engine reaches operating temperature, 8–10 min.   Continue operation under these conditions for an additional 6 min.   Accelerate at part throttle to 90 km/h (55 mph) with this speed maintained for 2 min.   Release the accelerator pedal for at least 10 s. This will allow the vehicle to enter the decel fuel cut off.   Safely stop the vehicle, with the engine in drive for automatic or neutral with the clutch pedal depressed and parking brake applied for manual. Allow the vehicle to idle for 2 min.   Shift the vehicle to park for automatic and neutral for manual. Turn OFF the ignition and exit the vehicle. Do NOT disturb the vehicle for 45 min.   Observe the Inspection/Maintenance (I/M) System Status with a scan tool. All of the I/M System Status indicators should display YES.   If the EVAP I/M System Status indicator displays NO, turn OFF the ignition, ensure that the vehicle meets the conditions for a cold start, and repeat steps 6-11 three more times, or until the EVAP I/M System Status indicator transitions to YES. If the indicator continues to display NO, refer to the Inspection/Maintenance (I/M) System DTC Table to identify the DTCs that did not run.   If any of the I/M System Status indicators display NO, refer to the Inspection/Maintenance (I/M) System DTC Table for the indicator which did not display YES. The I/M System DTC Table identifies the DTCs associated with each I/M System Status Indicator.   Observe the I/M Test DTC information with a scan tool. Verify there are no I/M Test DTCs present. If an I/M Test DTC is set, diagnose the DTC using the Diagnostic Trouble Code (DTC) List - Vehicle and refer to Inspection/Maintenance System Check.   Observe the engine DTC information with a scan tool. Verify no DTCs are present. If a DTC is set, diagnose using the Diagnostic Trouble Code (DTC) List - Vehicle. After repairs, perform the Inspection/Maintenance Complete System Set Procedure to verify no further DTCs are set.       Looks like one procedure to me.  Repeated as necessary.

      6.2L L87 Powertrain Engine Noise (Lifter Failure) Question

      By calgator73 · Posted

      My 2020 AT4 6.2 has had the valve spring issue addressed at ~200 miles, front cover/pump replaced at 18k, water pump at 34k and idler pully at 65k.  I would agree with ditching by 100k unless you elect to go with upgraded hardware...say built 10l80 and an lt4 or l8p swap.

      You might find the drive cycle you need somewhere on charm.li (website), otherwise I suggest a subscription to alldata.com to get them for your truck.
