Hello there guys,
Had my fluids changed today, since I got paranoid with all this talk about what is, or might be, best to do. It was not an inexpensive deal, though. I had engine, tranny (auto) and rear end changed. Total was $540.39.
Of course, I'm now good for many worry free miles on tranny and rear end. I made sure they didn't reset my "oil change indicator" since my Normal oil changes are included in my "care package"..... this way I'll get one
more early change out of the deal and my engine should be void of any excessive metal particles from my break in period.
It would have been much less without the tranny flush, but it did give me some more peace of mind to change all the fluids. Because of the warning in this thread, I had the dealer check the rear end shortly after getting
the car and it was fine....
I watched them check it by topping it off. It took maybe an ounce or two.
I mentioned this to the woman who got us in to see our car built. I emailed to ask her if the fluid was checked in the full audit I got. Her reply:
The differential fluid is not checked at the plant. It comes to us prefilled.
Thank you for the heads up on the potential issue. I forwarded your note onto our warranty group and they are investigating it through research in the warranty database. We have also contacted our brand quality manager to determine if differential fluid is checked at the dealer (delivery inspection check). You can always ask the dealer about your concern.
any oil with the GM4718M spec on the label (probably back label) will be just fine ... let's not start an oil war
taking possession of 2012 V sedan in 2 weeks. Do i have the fluids checked prior to taking delivery, or do i drive approximately 700 miles and then take it to the dealer to check levels. By the way, someone was saying that they had the fluids changed it cost almost $550. Is this not something that would be covered under the warranty? Maybe i am thinking that topping off should be covered, but not a full flush and refill. Anyway, appreciate this info. Sold my 04 CTSV and thought i would never let it go, until i test drove the 2012 - iyiyiy.
topping off to correct levels should be covered by the warranty ... drain and refill is not in the service recommendations so it would not be covered (for no reason)
I always change all fluids (excluding brake fluid) at about 500 miles in order to flush out any manufacturing debris. Some metal particles and once in awhile, some malitious intententional contamination needs purging.:helpless:
And.... I always check post-flush for correct fluid levels following the 500-mile fluid replacement. One time, the manual transmission oil level was a half-quart low - Dealer mechanic trying to make an extra $25.00 by not installing the full design fill of expensive mineral oil. I actually (really did) encountered a mechanic that did not know how to change the rear differential oil. On my Jeep, there is no drain plug; one must open the Differential "pumpkin" to drain the oil. Of course, the gasket will have to be replaced. For some reason there is only an upper fill plug.
and how is a dealer tech going to make money by not filling your fluid to the correct level? techs can't turn parts (especially fluids) into cash very easily
first, it's a BIG BIG no-no ... first offense is grounds for termination at our shop
did they charge you for the correct amount of fluid but leave a quart low?
so you suspect the tech kept the extra bottle and then sold it back to the dealer to be used on another car?
i've heard of techs doing stuff like that to get fluids for their personal cars (saving themselves money) - still just as big of a no-no
but i've never heard of them selling the fluids to make some cash
unethical people are everywhere ... that's why trust is such a big factor in choosing who to do business with (especially in a service oriented industries like automotive, finance and hospitality)
The diff is covered under the TSB if you get a clunk, "chatter" or howling.
#10-04-20-001B: Rear Axle Clunk and/or Chatter Type Noise on Turns (Drain/Refill Rear Differential Fluid) - (Apr 21, 2010)
Subject: Rear Axle Clunk and/or Chatter Type Noise on Turns (Drain/Refill Rear Differential Fluid)
Models: 2003-2010 Cadillac CTS, Sport Wagon (Including V-Series and Export)
2004-2009 Cadillac SRX (Including Export)
2005-2010 Cadillac STS (Including V-Series and Export)
Equipped with Limited Slip Differential (RPO G80)
Some customers may comment on a clunk and/or chatter type noise from the rear of the vehicle while making turns.
This condition may be worse on vehicles built prior to the 2008 model year. Carbon-faced clutch plates were introduced into production in the 2008 model year and have decreased the likelihood of the clutch plate chatter.
This condition may be caused by slip/stick of the posi-traction clutch plates due to insufficient limited-slip axle additive. As plates slip and stick, a jumping or jerking feel occurs accompanied by a clunk noise.
Important: DO NOT remove the differential cover. It is not necessary to flush the old fluid from the differential.
Drain and refill the rear differential with fluid, GM P/N 88862624 (in Canada, 88862625). Refer to the Axle Lubricant Change procedure in SI.
This fluid includes a friction modifier already added with a different formulation that lasts longer and does not break down over time.

How do you know if you have a diff cooler? I'm looking to get my diff fluid changed soon. Thanks -Steve
I just had my diff fluid changed today with the 88862624 fluid and they put down they used 2 bottles does that mean I have a diff cooler?
A little confused by this topic.
Was under the impression that the full service warranty on 2011 and up Caddies covered all of these items.
If your fluids are wrong, isn't that on GM/Cadillac?
Was certainly my impression when I went to the 2011 model year.
