    What other fluids satisfy all gm's standards? None. I know its pretty much a rip off but i am a play it safe kinda guy.

    RICSCH

    I have almost 17,500 on my truck. No problem with rear axle. Just preventative maintenance

    told you to use would have met all of GM's standards? doh! I used lubriplate 75-90w when I changed mine. Is it better than what GM has specified....you betcha. Same goes for most aftermarket petroleum products. BTW, lubriplate is specified by GM as a lubricant to use on the door hinges, etc.

    As far as warranty, I think the dealer and GM would be hard pressed to prove that the oil you used in your rearend caused its failure. Same as the fram filters....they may be crap but no one can prove that it caused an engine to fail.

    Has anyone had the driveline resonate or rattle when towing or hauling heavy loads in overdrive with the torque converter locked when engine is lugging before a shift? Problem happens in 3rd also under the same conditions. This truck is a V-6 auto 4x4 reg cab.

    I think it is the driveshaft, but not sure. When using tow/haul mode when towing over 60 mph the truck will shift in OD unless I keep it in 3rd. When towing about 5000 lbs the truck sounds like a piece of junk when the engine is running at low RPMs with locked torque converter and the truck is under heavy load. Is there a TSB on this?

    If there is a TSB I hope they do not reprogram the transmission to unlock the torque converter earlier because this will generate more heat in the transmission. Anytime the torque converter is open it is slipping and generating heat, but I could see GM doing that.

    Is this a good idea? Does GM void the warranty if you use one? I connot find a cooler that has the correct fitting to the radiator. For some reason, none of the half ton trucks come from the factory with one.

    sounds like what my truck is doing at about 35mph. I was told there is no fix. This after taking it in twice.

    I did kinda fix it but not totally. I set my HPIII for shiftfirmness so it doesnt lug between 30-40mph as much but it still does.

    Ryan, You do not void the warranty by using other mfr's. products, remember that federal law quoted here quite a few times? I don't recall the name, but I'm sure one of our fellow readers here could quote it for you. The Vehilce manufactorers are trying to create a monopoly by telling you this and they are dead wrong. It's like telling me if I buy a product made by Menards and don't by their replacement parts for a repair I void the warranty...baloney! Thats why you have Aftermarket Parts Mfr's. Assoc. so everyone gets a piece of the pie!

    Obyone is correct, go to PepBoys, AutoZone, NAPA, CarQuest etc. or whatever parts store you have in your neck of the woods and get the 75w-90 gear lube you need, save a few bucks and take your girlfriend out to the drive-in movies, the rest is up to you.

    I know it wont void my waarranty unless they can prove it. And if something does happen they can say it doesnt meet a spec (i forget which one it is) and wont cover it.

    There is a specification which mobil 1 etc does not meet.

    How bout i spend the extra money and take the gf out and have piece of mind we are going to make it there and back?

    is generated more with the tranny hunting back and forth for a norm under the driving conditions/load carried. If your hauling heavy loads why would you even think about running in overdrive, put it in 3rd Tow/Haul mode and leave it be.
    As for an oil cooler you must not have the factory tow package because it comes standard w/oil cooler otherwise you may have to get the OEM from dealer since you have run into problem locating aftermarket.

    You sure don't have much faith in your Chevrolet product do you, since when is a dealer going to send your tranny fluid out for analysis upon a failure??? if your rearend blows in that truck I'd say you need some driving lessons from Skip Barber.
    But like Oby says dealers couldn't survive without people who think like you, but whatever floats your boat and makes you happy, good luck on this one now.

    Dealers dont come up with the specs for our trucks. They dont print them in our owners manual either
  • obyoneobyone Posts: 8,065
    Moss-Magnuson Act prohibits the dealer from doing exactly what you're saying.

    What specifically doesn't Mobil1 meet in terms of specifications? What about Royal Purple? Lubriplate? Who do you think makes that special GM gear oil? Well....it ain't GM.


    That's all for now....no sense in beating a dead horse...or jackass in this case....hehe

  • ryanbabryanbab Posts: 7,240
    getting so worked up over this?

    When I call my dealer about getting the diff. fluid changed on my 2001 Z-71 with a locking diff. he quoted me a price of around $155. He said that included $90 for the synthetic fluid, $10 for an additive, and $55 for the labor. Do you have any idea what is this additive is they are talking about?

  • ryanbabryanbab Posts: 7,240
    Tell that dealer if he puts that additive in the rear end of your truck you will beat him with a baseball bat. Only the pre 99 trucks use that stuff. Everything else sound right.


    Seriously why dont you do it yourself and save some money?

    Looks pretty easy only thing i am worried about is putting the fluid back. Looks tricky

    SPECIAL GM fluid....but the guy at the dealer says....no synthetic? Life sure is tough on these major projects....hehe
  • ryanbabryanbab Posts: 7,240
    Went to "my" dealership. Got 3 quarts and a gasket.

    All ready to go now. THis guy tried to argue with me. He like you NEVER have to change the rear end fluid. Ok whatever dude. I was like well your gonna lose a big sale. He shut up quick

    Where do you guys get all the info/pics on the maintenance for your Rado's?

    I agree with oby and ray. Synthetic is NOT going to void your warranty. If Chevy told you that that is BS!

    My 2 cents anyway...

    Jim
  • ryanbabryanbab Posts: 7,240
    Synthetic is what you are supposed to use in the rear end.

    Gm says the fluid you use has to meet certain specs. If it doesnt meet the spec its no good in my book

    Ryan
  • obyoneobyone Posts: 8,065
    Exactly, what specs doesn't Mobil 1 meet?
