I've now talked to several techs at the dealer I use. They were under the impression that the gear lube (GM part #89021677) contained the LSD additive because it is synthetic. I told them that just because it is synthetic does not mean it has the additive. Royal Purple synthetic gear lube does contain the additive. However, Mobil 1 gear lube does not. This whole issue seems to be a GM training issue. The vast majority of the techs don't have a clear understanding of the need for LSD differentials to have an additive. They also don't understand that synthetic gear lube does not necessarily contain the LSD additive.
IMO this is a DEALERSHIP training issue! Not GM's ... GM can send out procedures that explicitly outline the EXACTLY way a repair is to be done - but, unless the tech doing the job follows that procedure JUST AS it is written then the issue lies with the tech, the service manager and the dealership.
I see this in my own company .... a person who has never driven a forklift is given a brief 10 minute "course" (after all its just a vehicle right!) - given a written test, a driving test, and voila - they're a forklift driver. Guess that's why we have damaged product everywhere
I suspect that many techs are simply being "told" the procedures as the last tech "remembers" them .... thus, the steps of the additive being left out!

Why should all the finger pointing be at the Techs?
GM has different differential lube for the Getrag units in the Solstice and the Corvette/SLX. The Corvette/SLX synthetic lube includes the friction modifer.
How about the Parts Departments role? In some dealerships the Tech tells them the job and they are responsible for filling their order with the required parts.

You are correct that it is a dealership training issue. It certainly is the responsibility of each individual dealership to enforce the repair procedures and policies as set forth by GM. I feel this is becoming fairly widespread as individual owners become more aware of the requirements for doing the recall procedures on LSD equipped cars. GM would be the only entity that would have full knowledge of how wide spread this issue is. As such, GM is in the best position to make all the individual dealerships aware of the requirement to use the additive in LSD's. The current situation seems broken, just saying individual dealerships need to follow procedure. The consumer, and ultimately GM, have the most to lose leaving it up to the dealerships.

Sorry SD .... If one of the Tech at the company I work for is working on a tool it is HIS responsibility to know the repair procedures/parts/etc. NOT anyone else.
IMO it is not the responsibility of a parts person that does NOT do any repairs on the vehicles to know what the TSB calls for. The Tech that works on my car is handed a copy of the TSB if one is applicable at the time my car is brought in - its up to HIM to follow the procedure, which in this case would to be sure to include the additive per the bulletin.

Just spoke to the Tech and was told that they did add the additive.
Well at least thats a load off of my mind. Now I just need to make sure the body shop does a good job with the repair.
Well I took my car into the dealership today to have the damage repaired from the recall work. I got a copy of my receipt for the recall work and guess what...no additive, only Gear Lub and Seal Kit.
I spoke to the service manager about this, he checked and said that the additive is not required and was not added. I told him is was needed, so he is going to add the additive at not additional charge. I hope I did the right thing.
Now he told me that because my diff was not leaking I did not need the additive?????
Oh and BTW...the service department was really really nice to me. Not what I got from the recall visit.

Did they drain your fluid or just inspect and top off? If they just topped off then my understanding is no additive is needed. Someone correct me if that is wrong

You are correct! If the differential is NOT drained the the additive is NOT required.
The recall procedure does not call for the draining of the differential.

Yes, but it also doesn't say not to drain the differential.
The first three versions of the recall bulletin suggested that the draining of the differential may insure the best repair by allowing no trapped fluid.
The TSB announcing the new Seal Kit in December 2007, makes the same statement.
The actual recall procedure in the recall bulletin, says to follow procedures found in esi (electronic service information or as I call it ever-changing service information).
Fluid and additive are allowable parts for the completion of the recall.
No clear right or wrong way to handle it. It appears that more and more dealerships are going the no drain way now than at first.

I have a 2006 that we just bought. How can I find out if this car has a LSD or not. Just had the recall done and had them change the gear lube, the work order only show the gear lube p/n.

The Option Code Label, which should be on the glove box door, would show RPO Code "G80" on cars equipped with Limited Slip Differentail.
It would also show as a $195 option on the original window sticker if you have the sticker.
Your dealership could also run the VIN through GM VIS and get a print out of the option the cars was built with.
